Does anyone elses transmission get warm or hot sometimes? I have about 91k miles on my 91Turbo... I have found that if I have been driving it a while the shifter and the area around my shifter gets particularly warm. If you unbutton the shift boot and let air come out very warm air comes out pretty fast... any ideas?

Check the fluid and change the filter, if it's an auto. If 5sp, just change the gear lube. If it isn't that, maybe it's just your exhaust heat coming through the hole there, it DOES run right next to the tranny, pretty much...

On a related topic:
Does anyone know the proper fluid temp for an 88 Auto tranny? I have a temp guage laying around that I plan to install, but I cant find what the optimal temp is...

Oil temp shoud stay around 165-180 for longevity. If you are feeling warm air come in, there is a boot under/in the tunnel. Yours might be ripped. I don't feel any air come through mine (AT).

after I put the short shifter in I know the rubber boot that it came with was loose but I have been noticing that my shifter gets pretty warm... Ill try and change the tranny fluid. that is one thing I have not yet done. Ill be replacing it with synthetic tranny fluid. Anyone know how many changes it takes to flush ALL the tranny fluid?

The tranny gets hot because of the difference between rwhp and hp. If that is say 10 hp at cruise (something like 10 000 Watts) thats the same amount of heat output as about 7 kettles. That makes your tranny hot fast!

Huh? Something about kettles and popcorn and jiffy lube or something like that.

Your tranny should heat up, it's a moving system just like your motor. If you've got an AT, check your tranny cooler and the lines to make sure it's not leaking anywhere, and you don't have a hole in your cooler from that time you hit a bird. Either way, change your tranny fluid, even if the heat isn't above normal levels, it's still good preventative maintenance.

probably has a lot to do with the exhaust. that old catalytic converter loves to soak up heat and radiate it outward. since the trans casing is aluminum, which is highly thermally conductive, it'll get nice and toasty as a result.

the only solution is to get rid of your catalytic converter. au revoir. :)

I did, I have 3" turbo back... the downpipe completely elimnated one and the other was cored... it still heats up like a mofo. I also have a manual, not auto...

I am gonna change the tranny fluid soon, tires as well... anyone have any recomendations for the tranny fluid change? Tips and tricks?
