alright i dont know if its normal or not but the tranny is getting super hot and as time progresses it fights going into gear...its like 5 times hotter than my heater??? (hard to describe) should the tranny be getting hot like this?

HOw hard is it to get into gears? Are you forcing it in?



Are you running the car hard? They got hot pretty easy just by abuse, or aggressive driving . Also the exhaust is right next to the tranny so the harder you fun, heat transfer to the tranny too.

My tends to get very hot in the summer or if I've been driving it for a while. But I need a new tranny soon so that might be your problem.

Yeah mine gets hot when driving hard for more than 30 minutes. I was thinking it was the exhaust causing this. Today I noticed the shifter was REALLY HOT! No problems with shifting just really hot. Normal? any help would be great.

so i took it to my mechanic... he says its b/c of the exhaust so close however it will damage the tranny if you use crappy fluids *non synthetic so i put synthetic in it and it cleaned up a bit ...no hard shifts i would never force it ...its just a little rough....not anymore tho...so use good synthectic...and exhaust wrap may help ...thanks guys https://www.nopistons.com/forums/pub...IR#>/bigok.gif

If you plan on racing your car make sure that you give it plenty of time to cool off before you race it because the heat will reduce your power through the trany. It killed my 1/4 mile times the one time I went to the track. That thing was rediculus hot and I run royal purple

my **** gets hot



i dont have the tranny heatshields anymore



im not really worried about it.

shpaintball 05-21-2007 08:32 PM

yea yea ...i just didnt want anything bad to be happening and now its all good i guess thats sorta a design flaw

Anybody ever use muffler wrap like the stuff sold for motorcycle pipes? That stuff insulates noise and temp. I have been thinking about using it and fabbing some heat sheilds.

I used header wrap when I made my headers. That seems to really keep the heat down under the engine bay more than the stock shield did. So if you were to wrap your down pipe it would work except that stuff is expensive for a long roll.
