Hi everyone, I have a 75 chevy k20 2x4 which recently started to leak transmission fluid. Does have a few good miles on it so i figured the transmission pan gasket was bad. After i changed that it still leaked and i ended up using a mirror to look on the passenger side of the transmission and it looks like the leak is coming from the servo cover. I believe it is a 350 turbo? But not sure. Since it is leaking out the bottom of the servo do i just replace the o-ring gasket? or is there more i need to fix? Also, how hard is it to remove the round servo cover? THANKS ALOT!
