After a delay of almost a year, I'm back on the "Money Pit" ('79 TR7 resto-mod with '76 engine and transmission).

I had rebuilt the transmission as part of the engine rebuild and I decided that I would now put in the transmission oil before installing the engine/transmission pair.

Boy was I lucky I decided to do that. The transmission leaked like a sieve. I mean, it was running out as fast as I was putting it in.

After I pulled the transmission, I looked for were the leak was located and found that it was at the 5th gear forward plate gasket. I also found that the bolts all around the transmission were very easy to loosen, not much more than finger tight.

I also found that the new rubber bushings I had installed on the shifter extension were beginning to crack after 1 year of non-use.

Well I need to order the new gaskets, poly bushings (this time), and a synchro pad to replace the one I dropped and can't find.

Oh what fun fixing your own car can be.

Larry, You made every one of us that do the same kind of stuff feel very good today. I admire you for even attempting the tranny! Two steps forward ,one step back, we will get there eventually, Jim

Larry,

I'm a little confused here. So you rebuilt the tranny yourself? And the tranny leaked because the case bolts weren't properly tightened down? So did tightening the case bolts fix the leak? Also with the case bolts now properly tightened, do you feel confident that everything inside the case is correctly secured? One thing I learned years ago when performing an operation like this is after you've double checked everything, check it again.

Yes, I rebuilt it myself. With the gaskets leaking, I am choosing to replace them rather than just tighten the bolts.

I must have been tired to not have tightened them,if that was the case.

I intend to goop the hell out of them, then use a torque wrench to assure they are tight and evenly so.

Thanks for the input.

Larry,

If the leak was just due to loose bolts I would think that just tightening them would solve the problem. You could always tighten the bolts, refill and see if it leaks. If you feel better about replacing the gaskets though, of course that's your call.

The gasket was oil soaked. Replacements are only a dollar and a half so I'll just replace them.

When replacing, particularly if you are "gooping" them up, remember that they do affect you end float on the gears (the one between the place and the trans body, the rear cover does not). So you should recheck that.

I gave up on British gasket technology a long time ago. Not enough crush provided in those paper thin gaskets, so I use non-hardening Permatex - a very thin layer. Life has gotten much better since I started that practice.

Yeah, some new owner down the road will be saying "WTF?" as he tears into my handiwork. Oh well. eye rolling smiley
