Derale pan on 4L80e
 

does anyone have one of their "cooling" pans installed on an 80'. I have one and the damn thing wont fit (hits the filter)...

i was gonna get one-which filter are you using, the late model one with 4 tits on it, or earlier one that is flat on the bottom
if you have the late one, maybe the early one will fit-do they mention anything in the insts.
how close is it?-if your using a shift kit w/v/b stiffiner, it makes it tighter, pushes the filter towards the pan

Using the late model filter... with the 4 tits
I think you got it because that is where the pan hits, along with the slightly thicker vlave body plate would do it. Nothing is mentioned but I will check the auto parts stores and atleast look at the earlier filters.

have been unable to find a flat pan... even at 3 auto stores

My Derale pan fits fine, but I have a 95 or 96 trans, so it's the earlier design.

Does your filter have the bumps on it? That has to be the difference....

Got it worked out.
For future reference, those with 4l80's; regardless of the year of your transmission, you must use the earlier model (flat) filter when using the derale pan.
