in my truck ive still have the stock transmition i was wondering how hot is two hot. With it chipped all the way up it gets to about 180 - 200 degrees. is that to hot for stock? i dont have trouble keeping it cool on a regular basis, but i wana know when to call it quits when im out rollin coal so i can upgrade my tranny on my own terms... not its... thanks lawson

 

I would say thats pretty hat at 230 you have to pull over. I could only get mine to 180 on my 140 hp tune and hot rodding it for a bit. Other than that in my daily tune last summer is ran 150. I put in another trucool trans cooler inline with my stock one and I have yet to see anything over 125.

 

how much was the cooler... and do u think it would b a wise investment?

 

140 shipped with all the fittings for a super duty. Yes lower trans temps equals longer life. I believe I read somewhere every 20 deg lower doubles fluid life. This is what I bought http://www.dieselsite.com/index.asp?...ROD&ProdID=205

 

Too cold is as bad as too hot...

Anywhere from 130-200 is fine. Unloaded temps should be 50-90* above air temps.

 

i agree with csipsd u dont want it to get to cool and u dont want it to get over 200 or stuff will start going wrong

 

your tranny temp should be 20 degrees cooler than the motor

 

so getting another cooler would not be a good idea?

 

if you do get another one, make it smaller one, not something that will push it below 130 on regular basis, i have a suncoast cooler and i have yet to see over 200 hot rodding it down the interstate

 

that sucsoast is fairly large isnt it
