The ideal operating temperature of transmission fluid is 175 degrees. Overheating occurs after the temperature surpasses 200 degrees, and the failure rate doubles for every additional 20 degree increase after that.

The ideal temperature for your transmission is 200 degrees. For every 20 degrees past 200, the lifespan of your transmission is reduced by a factor of 2. In other words, if you hit 220 degrees, you can expect to get about half the normal life out of your transmission. Hot transmissions give off an odor.

about 195°F.

Without enough transmission fluid or effective fluid, your transmission will start acting out. The ideal fluid temperature is under 175 degrees, but as fluid ages it starts to break down and lose its capacity to cool down the transmission. This is when transmission overheating occurs. At 220 degrees, varnish forms.

175 to 220 degrees

This article takes a closer look at three common signs of transmission overheating.

1. Acrid Burning Odor. Transmissions change gears using principles of hydraulic power.
2. Slow Response Times. A transmission stands a much greater chance of overheating if fluid levels drop too low.
3. Transmission Slipping.

What to do when your transmission is overheating:

1. Stop driving immediately and let your transmission cool down.
2. Make a note of what you were doing, where you are, what’s happening (noises, etc.)
3. After cooling down, start back up & gingerly continue on your way.

A transmission that frequently overheats can cause fluid to leak from the transmission, so if you are constantly replacing the fluid, it’s a good indication of a leak. A slipping transmission is also an indication of low, dirty, or burnt transmission fluid. You also need to be aware of the check engine light.

Old, worn out, or burned fluid will cause the transmission to run hot. Transmission slipping is another hint that the fluid is low and old. A defective solenoid can cause the transmission to run hot. Driving habits, conditions, and weather are other possible causes of transmission overheating.

Change the transmission fluid regularly We recommend that you change the transmission fluid every 30,000 to 60,000 miles, and more often if you drive long-haul routes, operate your vehicle in hot climates, or tow heavy loads. This reduces transmission wear, which in turn reduces the risks of overheating.

The ideal temperature for it is 175 degrees, plus or minus 25 degrees, and when the transmission gets below zero degrees, it gets too thick. The fluid can also fail to lubricate parts when it is too cold, wearing parts down unnecessarily.

Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.

If your transmission slips only when it’s cold, then there could be three possible reasons. The first one could be that your engine is low on transmission fluid and could use some more. The second reason could be that the fluid has become old and denatured, and needs to be changed.

There really isn’t a reason to warm it up, unless you are in extreme sub-zero temps. Letting the engine idle for a couple minutes should do the trick (that is even a hot debate). If you are experiencing trouble shifting when the trans is cold, it could be an indication of upcoming issues, so get it checked out.

So, when it’s extremely cold outside, start the engine, and let it idle for a minute or so before putting it in gear or under load. This allows engine oil and transmission fluid to circulate and lubricate. Then shift into gear and let the engine and transmission warm another 30 to 60 seconds.

Let it run for about 5 minutes so that it can warm up. Some car manufacturers will recommend you turn the engine off before checking the transmission fluid, but most don’t recommend this.

Your car’s engine should be running when you add fluid to the transmission, but you should have the transmission in park and the handbrake activated for safety. Check the owner’s manual for instructions on selecting the correct transmission fluid for your vehicle.

Transmission Fluid Leakage: Adding too much fluid will cause high pressure inside of your transmission. This is very bad and could cause your transmission to start leaking fluid everywhere. This can cause wear and tear on your transmission and damage the system in the long run.

Pull out the transmission fluid dipstick. Wipe the dipstick on a clean rag or paper towel, reinsert it and pull it out again to check the transmission fluid level. The fluid level should be between two marks labeled either “Full” and “Add” or “Hot” and “Cold.” Usually, you should not have to add transmission fluid.

How can you tell if your transmission fluid is low? It’s important to keep an eye on these easily identifiable symptoms of low transmission fluid levels: Dashboard Warning Lights: If your transmission fluid temperature is hotter than usual, you will see a warning light on your dashboard.

Symptoms of Low Transmission Fluid

• Drips or puddles underneath the car.
• Difficulty shifting through gears and/or slipping.
• Shuddering or shaking.
• Lurching or sudden jerks.
• Transmission won’t engage.
• Humming or clunking noises.
• A burning smell.

Low-quality transmission fluid – or driving without transmission fluid altogether – can cause a number of problems such as transmission failure, gear slipping, a hard time shifting, and a few more issues.

7 Early Signs of Potential Transmission Failure

• Transmission Warning Light.
• Bumping Noises While in Neutral.
• Leaking Transmission Fluid.
• Whining Noises.
• Uneven Gear Shifting.
• Transmission Hesitation.
• Slipping Gears.

Make Your Transmission Last Longer

1. Check fluid levels. Transmission fluid keeps everything running smoothly, so it makes sense that if the fluid level is down that it will mean you are going to run into problems.
2. Fix any problem immediately.
3. Watch how you drive.
4. Get your car serviced.
5. Watch how you use an automatic.

As any car owner will agree, saving a transmission and avoiding major transmission service or car repair costs are very worthwhile goals. Indeed, some transmission shops and dealerships are quite expensive and lack experience with today’s complex transmissions, so it’s not just a about saving money.

Transmission problems can cause the check engine light to come on as well, however it’s not always as apparent as other components within the vehicle. If there is a transmission issue, this equipment will be able to target where the problem originated, and then supply an error code to help identify the problem.

1. Turn the key to position 2. You should see all the dash lights come on.
2. Press the gas pedal all the way.
3. Wait.
4. Turn key to OFF, position 0.
5. Release the gas pedal.
6. Wait 2 minutes.
7. Start the car and drive.

Here’s a look at bad driving habits that can destroy your transmission.

1. Delay Transmission Maintenance.
2. Slam You Brakes.
3. Never Use Parking Brake.
4. Pound the Gas Pedal.
5. Don’t Stop Before Shifting from Drive to Reverse.
6. Never Check Transmission Fluid.

Major transmission repair requires disassembling, inspection, cleaning, and rebuilding. It’s labor intensive and cost prohibitive. Luckily, transmission failure doesn’t usually happen without warning. There are several warning signs that your transmission’s going out.
