I want to install a air transmission cooler. I am very lost on this topic but i figure it will provide good tanny insurance. I know how to do an automatic but i am real confused on what i need for the six speed. B&M sells nice coolers??? Please helpB&M Trans oil cooler

 

The difficult part of this would be to connect an oil pump. You would either have to tap the tranny housing, or use the drain and fill holes. Automatics already have pumps built in to pump the ATF through the radiator.

 

Could i use an inline type oil pump? Would this mod even be worth it?

 

It's a whole lot more work than what it provides. There are no fluid inlet or outlet fittings on the trans, it sealed with the exception of having a vent.

Automatics transfer power through the fluid in the torque convertor. There is not mechanical connection between the trans and the engine on an automatic. There is LOTS of heat generated by the convertor, and clutches. That's why they need a cooler.

Very few manual trans need one. They don't develop the same amount of heat that an auto does. Unless you decide to go endurance road racing, I wouldn't even bother.

From one of your previous posts, I'm guessing that you are trying to fix a grinding problem by adding a cooler. It's not going to work.


BTW, the S's trans uses an internal oil pump to supply pressurized oil to the gears/shafts inside the trans.

 

Unless you road race in enduros, you have a tough business case to propose where the cost and risks are overcome by the benefits. Doubt it is worth it to you.

 

No its not worth it to me. Thanks everyone for your info, today i put some redline MT-90 in and changed the diff fluid i used have redline half lucas synthetic stabilizer and in the diff i used 100% lucas. I have not heard that combo yet but so far my S is running great the grind is almost gone and the diff is smooth as butter. The lucas 100% synth is like 14.95 a bottle at Advanced. Thanks again

 

Not sure which Lucas product you used, but this might be something helpful, but not comforting:

The Ol' Professor says do a lot of research, or ask about, any additive you consider in your beloved car - think of it in the same way as would you take a cancer cure from someone with an Internet site? You may choose to ignore our help, but at least you have been given full disclosure. Peace out!

 

Well i guess i know what i am doing tomarrow
Changing out all that crap again what a load of crap!!
Thanks Road Rage for looking out

 

Although the transmission does get balky when overheated, most of us have found we can minimize it with frequent changes of aftermarket fluid, and live with the problem when it does come up. There are small coolers that incorporate an electric pump to pull lube from the drain hole, pass it through a little cooler, and back into the fill hole. The problems of custom mounting in limited space are enough for most to conclude it is not worth the trouble.

 

After changing from MT-90 to GM Synchromesh Friction Modified, I haven't even thought about my transmission. I don't think I've had a grind in 10K miles, and this is the longest I've ever gone without changing the fluid.
