Check out page 2. This was enough to make me feel comfortable doing the mod.

Re: Tranny cooler mod??
awesome pdx, that does help.
i need to really get on this since i am starting to have some bleed through issue with my engine and so I am sure this could be right behind it.
i would hate to get stuck out on the road in the middle of no where and look at a few thousand to fix the issue.
BTW, once the cooler is external, is there any way to remove the internal one?
(I mean without completely taking apart the trans)

Re: Tranny cooler mod??
I think the tranny cooler on there from GM is external as well, it just passes through the radiator.... But to tell you the truth I really dont know.
All I know is what I've read and that is that the radiator fails because the tranny is tied into the radiator you get water and tranny oil mixing.
I'll know for sure when I tear into it.

Re: Tranny cooler mod??
Installed mine yesterday. Went pretty smooth.
The new cooler is a tight fit. If you're off to the passenger side too much the hood won't close. I actually had to remove the bottom bolt on the power steering cooler so I could swing it over to the driver side. This allowed me to move the tranny cooler over just enough to 1) use the old tranny cooler mounting bolt hole on top driver side and 2) allow the hood to close. It's still tight. Could say it fit like a glove!
That could have ended up being the biggest setback, if I would have cut hoses and mounted the cooler without making sure the hood closed. Installer beware! : )
Glad to have finally got this out of the way. Next up is Corvette servo!

Firms up the shift from 1-2 and prolongs the life of the tranny.

Re: Tranny cooler mod??
Where did you get your Corvette Servo from and how much did it run? Also, was it hard to install? I am looking to do the same mod, wondering if it is too complicated for me or my mechanic to do...
Let me know where you got it from though if you could...
