Bill thanks for the pic. I had the laptop up in the air to simulate what it's gonna look like when I'm on my back in the garage....LOL! So....it sounds like that filter seal is a real problem and should be avoided unless changing it is absolutely necessary?
I plan on installing the shift kit with the trans on the car, so if it's no accessible from the bottom, it ain't getting changed. Here's the kit I got from Triple Edge:
4T65E-Shift-Kit-Combo-Kit
It's basically the TransGo shift kit with the accumulator gasket, etc. Do I replace or re-use the pan gasket? Is there an upgraded gasket number if I need one?
BTW, thanks for the PB link, but pics are meaningless without your expert narrative. Seriously, as good as the pic above is, it wouldn't mean anything without know what part was what.
