Does Transmission Fluid Need To Be Cooled?

Should I bypass radiator transmission cooler?

IMHO it is better to bypass the built-in cooler.

This is because the transmission adds heat to the cooling system, and you want the engine to run at a constant temp, but depending on road conditions, the transmission may opr may not be running hot.

Therefore you want a separate cooling system fo r the transmission..

How do you know if you have a transmission cooler?

Transmission Temperature Increase If you did not notice the transmission fluid on the ground, or the lack of shift quality, odds are you will you will know when the transmission is getting too hot. This can be one of the most noticeable clogged transmission cooler symptoms.

Does my radiator have a transmission cooler?

Nearly every modern vehicle these days has an automatic transmission. … If you are towing, however, an extra cooler, used in addition to the radiator trans cooler, will help keep the transmission from overheating. The cooling tubes for the transmission cooler are usually located inside one of the tanks.

Why do transmission lines go to radiator?

Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. … Your car’s transmission lines are essential to preventing the transmission from overheating by carrying hot fluid away from the transmission until it is cooled and subsequently pumped back into the transmission.

Can I use rubber hose for transmission cooling lines?

Keeping this in view, can I use rubber hose for transmission cooling lines? You could run it all in rubber and be fine so long as it doesn’t chaffe or get pinched. If you are that concerned you could run braided hose with AN fittings but it can get pricey quick. Rubber trans line will hold just fine.

Is a transmission cooler necessary?

Do I Need a Transmission Cooler? Transmission coolers help to protect your transmission when you turn up the heat. Transmission Coolers help transmissions deal with the added stress and heat caused by towing boats, trailers and other heavy objects.

How is a transmission cooled?

In almost all vehicles with an automatic transmission there is a transmission cooler placed inside the radiator. … The auxiliary cooler is cooled by air flow while the cooler inside the radiator is surrounded by antifreeze which is a controlled environment.

Can transmission fluid be cool?

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. … If water is in it when cold, it will freeze at 32 degrees Fahrenheit.

What temperature is too hot for transmission fluid?

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.

How do I keep my transmission cool while towing?

Adding a simple auxiliary cooler inline with the factory unit can nearly double the life of transmission fluid, keeping your gearbox happy and healthy for a long time. Also helpful are aftermarket aluminum pans. Their added fluid capacity and finned heat-sink design provide additional cooling as well.

What is a good transmission temperature?

200 degreesThe 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.

Does transmission fluid run through the radiator?

All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid.

How much does it cost to install transmission cooler?

The cost to install a transmission cooler varies depending on the type and size of transmission cooler being installed. On average, a transmission cooler for a standard vehicle performing simple day-to-day driving may cost anywhere between $20 and $80.

Can a transmission cooler be too big?

Too big could be a concern if mounted in the front of the rad creating a loss of air flow to keep the engine cooled . Years ago , GM released a TSB about overcooling the transmission in cold climates . Transmission fluid would actually turn to somewhat of a gel .

What transmission temp is too high?

#1 Cause of Failure 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.

Can you bypass transmission cooler?

It is possible to bypass the factory cooler in the radiator by blocking off the input/output locations for the transmission cooler on the radiator. You would then need to mount the largest possible cooler that you can get to fit or install a remote cooler with its own fan.

Do all vehicles have transmission coolers?

While all automatic transmission equipped vehicles have a transmission cooler in their radiator, this might sometimes not be enough to properly cool your transmission fluid.

How do I choose a transmission cooler?

Before selecting a transmission cooler, you need to know the GVWR for your particular car. The GVWR number can range from 10,000 to more than 30,000 pounds, and a higher number indicates that your car uses more fluid and needs a higher efficiency cooler.
