Default Tranny cooler idea???

I have a 98 EX with MT. I had to replace my radiator and the only one i could find was one for a AT. I guess that that is the only kind they sell. It has the two ports for the AT cooling lines. Could that be used to cool a MT? If so where on the MT would i run the lines from and to? If it wont work just let me know.

BTW I want to cool my tranny down because I live in the mountains and I feel it is getting a little too hot.

Thanks for any input you have.

no luck man...........the only way to cool transmission fluid is by pumping it through a cooler or buying a finned tranny pan whitch our manuals cannot use.

Would a pump like this work to circulate the fluid through the tranny and the radiator?

It sounds like its more headache than its worth. How have you come to determine that your trans is running too hot?

When I changed the fluid a few weeks ago it smelled burned. I am going to change it again in a month or so and see what it looks like. I am not planning on doing this idea anytime soon. I was just wondering if I needed to, could I do it.

never heard of doing that, though.
do they still recommend 10 w 30 or 10 w 40 oil in there? that is what is shown in the manual for 1988 ?

if yoru really serious about cooling yoru fluid then give that pump a try, remove the transmission, drill 2 holes(one at the bottom of the oil level for suction, on right at the top oil level) tap the holes and install barbed fittings and be sure to get the fluid level topped off with the cooler full. my main concern would be aireation.

damn i cannot spell "YOUR" right ever...............

Yeah, they still say to put 10W30 in them. I used Royal Purple this time.

If I end up doing this i will post a DIY about it. Thanks for the advice guys. Is there something I overlooking that would make the fluid smell bad?

Your manual trans definately does not need an oil cooling system, especially if you're running 10w30 in it. That's nice and thick as far as that application requires and it's really better for your gearbox if you've got plenty of nice, hot, oil in it.
An auto trans has a cooling system becase, for one, it uses synthetic auto trans specific fluid (usually) which not only is a lubricant, but it's part of a hydraluic circuit. The pressure from the integrated hydraulic oil pump is sufficient to pump the fluid through to the cooler and back so no external pumping device is needed in an auto trans. Also, an auto trans makes more heat than a manual.
See, in a manual trans, the constant-mesh gearset doesn't generate nearly as much heat as a torque converter and all of the clutch packs in an auto trans. I know that the Honda auto trans is a little different than most, having a manual-esque setup with what are essentially hydraulic synchronizers, but clutch packs are clutch packs: made of a paper-based friction material on some very thin plates. Gotta keep those boys cool, indeed.
Also, later model auto transmissions have a number of electric components that might have a certain amount of heat-sensitivity that require a little protection.
