it is not a necesity, but it is worth the money

 

The "F" stands for fluid. A tranny cooler cools the fluid that is pumped through it from the transmission. The fluid then flows back through the tranny and carries heat from the tranny to the cooler and repeats the process. Essentially a radiator for the tranny.

 

I am in the transmission rebuild biz.A tranny cooler is a good idea for ALL cars.Heat kills auto trannys.If you can put one on do it.Its just good insurance.

 

Yes, it definitely helps to prolong trans life. I would think a Hayden cooler would be way less than that one though.

 

To the person who said it was for car BEING towed....UMMM think again! If you are towing the car, then the engine is not on, so the tranny pump is not moving. The torque converter is what turns the pump and the motor is what turns the converter. The tires don't turn the motor OR the pump. If you tow the car, it either needs to be on a dolly(drive wheels off the ground) or a manual tranny and in neutral because there are parts moving whether it is in neutral or not. One thing that DOESN'T move, though, is the pump.
And I agree...a tranny cooler will save the live of the internal parts of a tranny, especially if you live in hilly areas and/or desert areas. Tranny fluid breaks down like oil does and heat is BAD for the tranny fluid. Also, you will be able to add a couple extra quarts of trans fluid because of the increased volume (hoses, cooler, etc.).

 

IF you get a tranny cooler, be sure to add a themostatically controlled valve so you are not cooling fluid when it's already cold. My '77 Mercedes diesel had a tranny cooler and this was on a car built like a tank. If it's worth the effort on an a classic Mercedes, it's worth the effort on an xB. An auto tranny can have up to 3,000 components. That a lot of stuff that can go bad.

 

That's not really necessary because there is no such thing as running a trans too cold. It will warm up regardless. It just won't get as hot as it did prior to adding the cooler.

 

I've always used tranny coolers there an excellent investment, if you put it infront of your radiator you will not have any cooling problems with the coolant or anything to that sort, I feel this is a great idea for these little cars with little motors and lots of strain on the tranny. The only thing is to make sure you install it really well and inspect it often to ensure your lines dont crack and you loose all your fluid ;-)
