shift it

I have been trying to get my tranny to stop dripping fluid. So far I have replaced the detent cable gasket, the grommet for the dipstick, the front seal, the real seal, the speedometer o-ring, and made sure that the modulator valve and the governor were seated properly and functioning properly. The only thing left really is the shift linkage. Has anyone here changed that seal, and if so how hard is it to do? I haven't really found any decent instructions, so any help on that would be appreciated too. Thanks in advance.

ATF leak

Hi, you didn't mention which trans you have but I will assume 350. The best way to replace the manual shaft seal is to remove the shaft. Take off the pan and remove the fat clip from the shaft and the large nut on the inside end of the shaft. Slide the shaft out (if it doesn't come out easy you may have to use a small file to smooth out the end where it attached to the shifter detent, the thing that looks like a rooster head, if you just force the shaft out you may ruin the case). Use a flat screwdriver to pop out the old seal being careful to not damage the case. Drive the new seal in with a hammer and the right size socket and reassemble. Make sure you get the large nut tight because they like to loosen up.

You should make sure the shaft fits good in the case, if it is very loose the new seal may only be a temporary fix. Also inspect the shaft when you have it out, if it looks damaged, replace it also.

Hope this helps,
Rick

========= you mention a gasket on the detent cable... there are 2 designs on the end of the cable. There should be an O-ring or a rubber sealing sleeve on the cable end. The O-ring type will have a groove for the O-ring to sit in.

If your's uses a sleeve type seal , the sleeve must be installed into the tranny case first , then the cable end lubed & slipped into the sleeve. IF you install the sleeve on the cable end , then puch it all into the tranny case the sealing sleeve will be damamged

thanks

thanks alot guys. The tranny is a turbo 350 and I replaced the seal today....works like a charm. As for the detent cable, it had more of a rubber washer towards the back end of the part that goes into the transmission that was torn. It is sealed up GOOD now!
