Is this a worthy while your in there?

Can I and/or should I replace all of the transmission seals while the engine and transmission is out of the car?

The Shift seal is leaking a little bit if I remember right. Other than that I don't think the tranny leaks so should I leave the Mainshaft Seal and Output Shaft Side Seal alone?

Can I even do these without tearing into the tranny?

Thanks

The shift seal is a no brainer, nearly no cost item. You should do it. Same applies to the output shaft seals. However, I may be in the minority but I would leave well enough alone on the mainshaft seal if it is dry right now.

If it is a 915, the the input shaft seal is pretty easy to do. You have to pull the throw out bearing guide tube and the input shaft seal resides inside.

You have to make a puller, but it is a matter of bending 3/16" rod and then using a pry bar leveraging the guide tube out. Not hard at all.

If you look at the guide tube, there are two holes in it to fit the puller.

Grady Clay posted the procedure and I followed. Took an hour, max. Upon assembling, make sure you wrap the splines of the shaft with something so you don't accidentally cut the inside of the new seal upon installation.

Is 87 a 915 and 88 a G50? Sorry If I am not remembering the years properly.
