TH400 oil pump seal
Quick question:
Just cleaned my low mileage and working TH400. Like to reseal all what’s easy possible now. Oil pan gasket, converter seal, rear seal , shift linkage seal,, speedometer seal, Modulator & finally dipstick Tube seal. How about the oil pump seal? Is that easy to swap ? The large O ring seal and the round paper seal .. Someone already done this? (65 Bonneville)

You really shouldn't have to change the paper gasket but a new seal is a good idea. If you change it be VERY careful you don't damage it or knock the little spring in it out of place.

I never opened or removed a pump before .. so if I will remove all the screws around and pull the pump forwards it’s possible that any springs behind will move ? Ok ..i think here’s the end for doing working by myself ... I will seal all what I can ..or have to think about let it inspect and doing all by a transmission shop.
thx for that advice!

If it's not leaking l wouldn't mess with it. I never seen one go bad. Just change the shaft seal. If bent on changing the big O ring take it to a tranny shop. You pull the pump out your opening a can of worms. You might well as go ahead and have them replace all the internal seals too.
