What Should The Transmission Temperature Be?

The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees bad things happen, starting with formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burn out, carbon is formed, and, ultimately, failure.Sep 25, 2018

What temp is too high for transmission?

Fluid Life Expectancy vs Temperature

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.

What should my transmission temperature be while driving?

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.

What temp is too low for transmission?

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.

When should I worry about my transmission temperature?

One light that you never want to see illuminated is the transmission temperature gauge warning light. Excessive heat is the enemy of your vehicle’s transmission and is responsible for many transmission problems. If you see this light come on, you should take immediate action.

How do I lower my transmission temperature?

Tips and Tricks to Cool a Transmission

Use an Additive. One of the simplest things you can do to keep your transmission cool and extend its life is to use a transmission fluid additive on a regular basis. …
Go Neutral. …
External Coolers.

What is the normal operating temperature of automatic transmission fluid?

between 175 and 225 degrees

According to TCI, the ideal operating temperature for automatic transmission fluid is between 175 and 225 degrees. At approximately 240 degrees, important additives in automatic transmission fluid (ATF) begin to cook. The result is the formation of varnish inside the transmission.

How do I check my transmission temperature?

Install the scan tool, start the vehicle and look for the transmission temperature. The fluid temperature should be between the 185- and 194-degree marks with an idle of 600 to 800 rpms. Remove the bolts and clips from the front fender well on the driver’s side, and locate the transmission fill plug; remove it.

How do I know if my transmission is overheating?

3 Symptoms of Transmission Overheating

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

What makes a transmission hot?

Reasons for overheating include low fluid levels, leaks, burned, old or dirty fluid, or problems with the solenoid. You can ensure the long life and efficient performance of your transmission – and your car – by doing some things to make sure it does not run too hot.

How cold is too cold for a transmission?

zero degrees

The viscosity of your vehicle’s transmission fluid changes and gets thicker when the conditions get cold. The ideal temperature for your transmission fluid is 175 degrees, plus or minus 25 degrees, however, when your transmission gets below zero degrees, it gets too thick.

What are the signs of low transmission fluid?

Signs of Low Transmission Fluid

Warning light.
Transmission overheating.
Difficulty in shifting gears.
Transmission fluid leakage.
Generation of unusual sounds.
Transmission slipping problems.

Is 160 a good transmission temperature?

Normal transmission fluid temperature is about 160-175 degrees. It might rise as high as 200-220 degrees under demanding conditions but hopefully it won’t go any higher. Transmission fluid degrades rapidly at higher temperatures. Cooked fluid and high operating temperature are transmission killers!

Can you over cool a transmission?

Yes, over cooling transmission fluid may cause some issues such as gelling up and restricting flow through the cooler lines and cooler itself, but this isn’t too common. This may occur when temperatures are consistently below freezing.

How often should the transmission fluid be changed?

every 30,000 to 60,000 miles

If you drive manual, most manufacturers will recommend changing your transmission fluid every 30,000 to 60,000 miles. If you have automatic, you can typically boost that range up to 60,000 to 100,000 miles. There’s no harm in changing your fluid early.

How do you know if you have water in your transmission?

One way that you can check to see whether your transmission has been damaged is to check the transmission fluid. If water has reached the transmission fluid, then it’s in the transmission system. Transmission fluid will usually be a bright red color, but if water has infiltrated it, the fluid will turn gray.

How do you read ATF temp?

Can I check the transmission fluid hot or cold?

Transmission fluid expands in heat and in order to receive accurate results, it must be under normal operating conditions. If the fluid is checked when the engine is cold, you may get false results indicating the fluid is low. Allow the engine to continue running while you check the level.

Why is my gear shift hot?

Transmissions shifts hard when hot because their parts tend to get damaged, worn, and malfunction under high heat levels. Your transmission needs fluid to keep cool and if the fluid leaks then it may create more heat and pressure.

Does coolant affect transmission?

It may seem like a rather remote possibility, but engine coolant, or anti-freeze can get into automatic transmission fluid. The temperature of transmission fluid is regulated inside the engine cooling system. … Any rupture of the internal radiator tank can allow coolant to mix with, and contaminate transmission fluid.

How do you stop a transmission from 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.

Does idling warm up transmission?

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.

How long does a transmission take to warm up?

Question: I see lots of advice on how long to warm up a car’s engine in cold weather. But doesn’t the automatic transmission require a warm-up as well? In below-zero weather I’ve had cars barely run or shift until the fluid warms up and flows better.

Does cold weather affect manual transmission?

Transmission fluids are also affected by cold temperatures. … As transmission fluid thickens in the cold, the synchronizers in manual transmissions cannot spin as quickly as they need to, which can severely impact the driver’s ability to shift until the fluid is warmed enough to provide proper flow – and protection.

Can transmission fluid get low without a leak?

No, you can’t leak transmission fluid into your engine. They are mechanically connected but there’s no way for fluid to get from one to the other.

Does changing transmission fluid help shifting?

If you catch a shifting issue very early, a transmission fluid flush can sometimes fix shifting issues. The fresh fluid helps clutch discs and steel discs bond and hold without slipping. The seal conditioners in the new fluid help soften the clutch piston lip seals so they seal better.

What happens if you drive with low transmission fluid?

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.

What is too hot for an Allison transmission?

Temperatures from 230-240 have been reached with no damage to the transmission. If you are seeing temps above 225 degrees on a regular basis you should check your fluid level. Fluid levels to high may cause excessive temperature. … These transmissions will run from 200-230 in the summer months when towing in hilly areas.

What temperature does ATF break down?

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.

Do I really need a transmission cooler?

For every 20F degree drop in transmission fluid temperature, you can expect to extend the fluid and equipment life, thereby extending the life of the vehicle. That’s why it is very important to have a quality transmission cooler, and more importantly, to have it professionally installed.

Can you have too many transmission coolers?

When it comes to your hot rod you really can’t have too much of a transmission cooler, but you can certainly not have enough. You will find there are various different types of cooler designs available and each has their own level of effectiveness.

Should transmission cooler be before or after radiator?

Should the cooler be installed before or after the radiator? Answer: We recommend installing the auxiliary cooler after the radiator to return the coolest fluid directly to the transmission.

Why you should never change transmission fluid?

If you don’t change your transmission fluid frequently, the dirty fluid will not serve as an effective lubricant and it won’t disperse heat well. This will cause wear and tear on the clutches and other parts of your transmission.

Is it better to flush or drain transmission fluid?

Proponents of transmission flushes will often argue that a flush is a better service because it replaces more of your transmission fluid. It’s true that removing your transmission pan or draining your transmission via its drain plug (as your car manufacturer intends) only removes about 70% of the fluid inside.

Which is better transmission flush or change?

A transmission fluid change will help to restore your system to good working order and is the cheaper option. It is also a relatively simple task that can be undertaken by vehicle owners. A transmission fluid flush is more costly, but will replace all of the fluid and any contaminants that have built up in the system.
