Leak with new seals

[87 evan]

I have an 85 k10 with a th350 ive replaced the front pump seal, pump gasket, o ring on the pump, and it still seems to leak, done the pan gasket, and the kickdown cable, still leaking dont know where to go from here

I've got a bit of a leak myself, on a TH400. Thought it was the pan, but nope. I'm pretty sure it's my shift linkage seal, but haven't tried putting that in yet. Watching to hear what the transmission masters say!

Could it be the pump bushing?

Because mine looks like its coming out behing the TC

Are you sure it’s not your RMS?

 

[87 evan]

I think its coming out between the tc and the pump

Would a bad pump make it leak

a bad bushing in the pump would. I had my TH400 out and cleaned the heck out of it and resealed. I just pulled my pump and took it in to a local shop. They disassembled and inspected the pump, pressed out the bushing and seal, cleaned it in the parts washer, then put a new bushing and seal in before putting the pump back together.... all in for $20 and about 20 minutes of time. I've been running it for a few weeks now and no leaks so far.

it was the dipstick tube leaking on to the tc

Now I understand, I was thinking torque converter when you typed tc, not transfer case. The little rubber grommet for dipstick tube is easy enough to replace.
