Here is an easy one. My tranny gasket was about gone so I replaced it. I dropped the pan, changed the filter and gasket and then replaced the pan. I put four qaurts Dextron/Mercron III tranny fluid into it. Started motor, let it get hot, shifted through all gears and checked the fluid level...
The tranny is marked as: on case - GM patent # 3088336 then 7-1, then P R07. On slider/shift cover plate - 3884685, on the spline/input shaft housing - GM14 and 38 (or 9)15020. The tranny case to the end of the input shaft measure 6-9/16". The pilot section in the bushing is 1.750" - 1.800" long, The 10 spline end is 2.350".
This was originally a bench seat car, which I plan to retain, and the hump is accurate for a non-console application. The shifter is a vintage piece (likely between ‘71 and ‘79) and is original to the timeframe that the conversion was done. Trans, tranny mount, crossmember, etc. appear to fit correctly without any obvious signs of modification.
The tranny shifts great from 1st to 2nd, shifts a little soft from 2nd to 3rd, but not too bad. When I try to go over 45 it starts to slip and gets progressively worse with speed.
