picked a 89 3/4t burb awhile back and it was puking tranny fluid out through the drainhole on the inspection cover so i figured it was the seal on the pump, no big deal $6 at lordco.
Put the new seal in today, still leaks like a bitch. the one I took out was new supposedly rebuild recent to sale and the guy said it was leaking ever since
What else could it be? pump gasket maybe?:dontknow:
current setup 400/241
I picked up another 400(32 spline) with a 208, will my driveshafts work on the 208 or will I have to use the 241?

Pump bushing. If there's too much clearance between the torque converter and the bushing it'll leak.(.002") Check the torque converter pump drive for cracks too. When is it leaking? running or shut off ??????

def pump bushing is done and your tc is prob siezed to the bushing so when you pull the torque itll come out with the bushing thats what happend to my 700r4 just pissed fluid out the front
