Rev up your engines, now there's two super expensive things on your car, there's the engine and there's the automatic transmission, you don't want either of them to go out.

You want them to last as long as possible.

So here's some transmission, tips, the most obvious and bring thing is, keep clean fluid in it.

You got to change it every so often, now decades ago, when I was a young mechanic, we had to change automatic transmission, fluid every 20-30,000 miles, but synthetic automatic transmission fluid lasts a lot longer, but don't be fooled by this nonsense.

That people say it's lifetime fluid.

You never need to change it.

You still need to change those too.

So just do that, every so often, it depends on each make and model, you got to do a little research like nissans I'd still do those every 30,000 miles, cuz their problematic transmissions, but something like a toyota.

You could get away with changing the fluid every 60-80,000 miles and you probably won't have any problems.

But now I'm going to talk about thing.

You might not have thought about.

The next thing, to make your transmission last as long as possible is your tires believe it or not.

Yes you want to have the correct tire pressure, because if your tire pressure is low.

Your tires are going to drag and have more friction, that makes the transmission work harder, the harder.

It works the faster it's going to wear out, and if you have one of these fancy new all wheel, drive vehicles, realize that all your tires have to be almost exactly the same size from wear, when your tires wear out or you get a blowout, on an all wheel- drive vehicle.

If you want the transmission to last, you have to replace all 4.

Tires at the same time.

With the same exact tires.

Most of the modern all wheel, drive systems, the computer.

Is continually monitoring tire speed/spin.

It lets the transmission.

Adapt to what's.

Happening, if one tire is a different size from the other.

Either front or back, it's going to be completely changing.

How much drive it? Gives to each wheel? To compensate for that, and while it's doing that compensation, the internals of many of these all wheel, drive transmissions will start to wear out much faster cuz.

They keep compensating, instead of just going normally and not having to compensate for the different size tire, which makes for a different speed, and it confuses the computer, and with the addition of all these modern anti collision avoidance system in cars, abs, brakes, lane assistance, even semi automatic braking on some of them.

It's important that your tire are all exactly the same, even on a two wheel, drive vehicle, because it's monitoring all 4 wheels and crazy things can happen if it thinks that one wheel in the back is rotating at a different speed than one wheel at the front.

Just because the tires are different.

Sizes, now another way to make them last.

As long as possible is this.

When you do change the fluid make sure you use the same fluid that came with the transmission.

In theory, lots of different ones can be mixed together, but with additive packages, and especially with these modern cvt transmissions, you want to stick with the exact fluid that the vehicle came.

With, all the modern cars come with high tech, synthetic fluid, it's a very good fluid.

It can take heat better, it lasts longer.

It doesn't break down as fast, it's a purer type of fluid, so you want to stick to that, and not take a chance by putting a different type in.

Nobody really knows.

What's in each of the different ones, you know that if it came with one particular one, you buy that same stuff, it's going to have the same additives, it's going to have the same exact viscosity and that's very important for a modern, transmission, and I know.

Really that's one of the reasons that a lot of transmissions don't have dipsticks or drain plugs anymore, because the manufacturers were worried that people are going to put the wrong kind of fluid in it and ruin the transmission, which I've seen quite a few times.

You really can't now a days, you better off paying a mechanic.

Who knows what he's doing to change your fluid on any modern car,? Some of them have multi step processes that can take an hour and a half, including road, test, hooking up a scan, tool, measuring temperature and pressure.

It gets really complicated, and you don't want to put a monkey wrench in the whole thing by using the wrong type of fluid, so stick to OEM fluid on any modern transmission.

Now another big tip to make your transmission last as long as possible is keep your cooling system in good shape, make sure the cooling fans are working, make sure there isn't any kind of blockage like paper bags or if you live out in the country, a zillion bugs that have covered up your radiator, and that's because most cars have transmission coolers that help cool the automatic transmission fluid, their generally built into the radiator of your car.

So if your radiator is running too hot, that's going to make your transmission run too hot too.

Now big truckers have known this for years.

They have temperature gauges for their transmissions.

But cars don't come that way, unless you special order one or put on a temperature gauge yourself, your not going to know what temperature your automatic transmission fluid is running at.

So really your not even going to get a warning.

If your radiator starts to overheat sure you know, you really need to work on it.

Let's say that the part that cools your transmission is kind of blocked.

It might be that your transmission is running a little bit hotter.

You don't have a gauge for that.

So this is an indirect thing.

Make sure your cooling system is in top shape, because that with make your transmission last longer, because the main enemy of automatic transmissions is heat, you want to keep friction down as much as possible.

Just the very running of itself creates friction.

You don't want to have extra friction added, because the cooling system isn't helping to cool that friction.


That would just make things worse.

If you have dirty transmission, fluid and a cooling system that wasn't working right, there's a double edge.

Sword, that's going to cut through your transmission and make it wear out faster.

You want to make sure you got a good battery and alternator in your car, because modern automatic transmission, their all computer controlled.

If you don't, have the correct battery voltage going, if the alternator is wearing out and either puts voltage, surges, or doesn't put enough voltage out, you can have transmission problems, you not might notice it much, but as time goes on it, the electronics are weak that can strain different parts of the transmission and cause them to break down.

It's a simple thing: to have your mechanic load test.

Your battery, load test your alternator every once in a while.

It's part of the job I do for my customers, all the time, sure in the old days, when a battery was going out and you try to start the car, it will go grunt and won't start, and you know the battery is getting low, but these modern cars, their completely different with all these electronics, I've, had a lot of cars that will just crank like mad, but they still won't start and it's a weak battery, because it doesn't have enough power to spin the engine and run all the electronics at the same time.

And since your transmission is now controlled by all this electronic stuff.

That makes it even more important to have a good battery and alternator, cuz if their not putting enough electricity out, most of the sensors on those things are either a 5 volt reference signal that have very little power, or 12 volt ones that still don't use all that much power.

And if the power has gone down, it won't shift right.

They might not even go down the road, the might just start slipping.

If the solenoids don't let them shift.

You can have all kinds of problems, which leads me to another thing that I have to talk about with electricity in your transmission, realize that your whole transmission is grounded, it's negative electricity, and if the ground cable from the battery to the frame, to the transmission, isn't working right, they can go haywire, all these transmissions solenoids.

They have to get a signal from the computer and the module yeah, but they also have to have negative electricity, because cars work on direct current.

In order for anything to work, it's got to have power and it's got to have ground, I've seen these things where from either corrosion or somebody worked on the car and they knocked a ground, strap loose or even worse, took it off and didn't put it back on, that will make the transmission go haywire if it doesn't have correct ground.

Now, if you have cars like GM that are know for having ground faults in them, it might not be a bad idea if you work on your car to get a good wiring diagram of where all the ground wires on the car are, and especially the transmission ground, wires and check them every once in a while when your car gets older, and the last tip is this.

If you got a dipstick like this old car check it every once in a while to make sure it's not loosing any fluid.

Now, of course modern transmissions, a lot of them, don't have dipsticks anymore.

So it's a good idea to crawl under there every once in a while and look at the transmission.

If it's fine, it will be bone dry, but it's all covered in oil and greasy.

You know something is wrong and have it looked at, and have the fluid topped up if necessary, because if you run a transmission when it's getting really low on fluid that will destroy them, I've had lots of customers.

Sometimes maybe they hit something and the bottom of the pan gets a leak on the transmission, and then they drive it around that way for quite some time, and when they bring it to me, I find the leak and put a new pan on it, but then they just don't work right, cuz the were running low and sucked a lot of air in and that ruined the inside of the transmission.

So now you know how to save thousands in transmission repair with some pretty simple stuff, cuz.

Let's face it, we're all in this together.

We don't want to spend our hard earned money, fixing an automatic transmission that we can keep from breaking in the first place.

So if you never want to miss another one of my new car repair videos, remember to ring that bell!.

Are transmission repairs worth it? ›

If the price of a new transmission is no more than 40% to 60% of your car's value, then it's probably worth the cost of repair. If your transmission is in good condition, there are benefits to repairing it rather than scrapping it entirely.

Can a automatic transmission be repaired? ›

Newer automatic transmission often requires a repair process that is quite complicated given that it needs specialized technology. Specifically, a computer.

Can car transmission be repaired? ›

Transmission repair is ideal for minor fixes. This type of repair can include fixing specific components, in-car repairs, various adjustments, and resealing jobs. Transmission repairs do not require the transmission to be rebuilt completely. This type of repair is not an option for transmissions with extensive damages.

Is transmission failure easy to fix? ›

The transmission consists of a variety of different parts itself. That is why transmission repair can be such a complicated process. There any number of different parts of the transmission that can be having problems, and the way to fix one of them is different from the way to fix another.

Can you rebuild a bad transmission? ›

If you're experiencing transmission problems, there are many different options to get your transmission running again. Generally, for both manual and automatic transmissions you have three options: transmission repair, transmission rebuild, or transmission replace.

Can you drive with a bad transmission? ›

The short answer to this question is no, you should not drive with a bad transmission. Sometimes, life happens, and you have to keep driving your vehicle even though you know that it needs to be serviced.

Do I use the whole bottle of Lucas Transmission Fix? ›

One 24 oz. bottle of Lucas Transmission Fix can be added to existing fluid without draining. A second bottle may be necessary in large or badly worn transmissions.

Is it OK to use Lucas Transmission Fix? ›

When it comes to avoiding costly transmission repairs, there's no better option for preventative maintenance than Lucas Transmissions Fix. With the exception of CVT transmissions, Transmission Fix is safe to use in all automatic transmissions and compatible with all transmission fluids.

How often can you put Lucas Transmission Fix in your car? ›

A: We recommend adding a bottle of Lucas Transmission Fix each time you change your transmission fluid (approximately every 30-40,000 miles), or adding a bottle to your current fluid to fix a small leak.

When should you not replace your transmission? ›

One of the most important factors is the age and mileage of the transmission. Automatic transmissions often fail between 80,000 and 150,000 miles. Manual transmissions can fail even sooner than that, especially when routine maintenance is neglected.

How long does a transmission repair last? ›

A great starting benchmark for rebuilt transmission success is the 30,000 to 40,000 mile mark. At the very least, a rebuilt unit should last this long.

How long does a good transmission last? ›

With proper maintenance, transmissions can last up to 300,000 miles or more. This includes changing the fluid in your transmission system and regular checkups. However, when you don't keep up with routine maintenance, your transmission might have problems at the 100,000-mile mark or even sooner.

Can you save a failing transmission? ›

If your transmission slipping fix was not completed in time, then it may cause devastating damage to the point where your vehicle will not be driveable. There is no “Quick Fix” at this point and it will require either transmission replacement or full disassembly to perform an internal transmission rebuild.

What is the method to reduce the transmission loss? ›

How to Reduce Losses in Transmission Lines
  1. Reduce ohmic losses by using a good electrical conductor with minimum resistance and maximum conductivity.
  2. Use a dielectric substrate of a low loss tangent and high dielectric constant to reduce dielectric losses and losses due to leakage currents.

How can transmission efficiency be improved? ›

You can improve the efficiency of transmission and distribution system by reducing energy losses from the resistance of the power lines. This can be done by using higher transmission voltages and increasing the wire sizes of tramsmission lines,which could also mean more investment.

Can you make a transmission stronger? ›

Here's a fact: manual or automatic transmission upgrades can do a lot of good for your car, starting from an increase in acceleration to ensuring that your transmission components do not break down when you least expect.
