Transmission Primary Pump Seal
 

Could use some help on dropping a ‘new-to-me’ transmission into my 89 300 sel. I have heard many times that while the Trans is out it would be wise to replace front, rear and primary pump seals. OK with front and rear, how and where do you find the primary pump seal.

Is there much to replacing the pump seal. Any ideas on where I could find info on the disassembly / assembly.

Thanks
