New leak in an old spot

[tsbt]

Last summer I replaced the main seal and clutch. Was leaking on the driveway. After putting her back together and taking a trip to NYC last year I arrived home with a new leak same spot. Thinking it's the front and rear seals in the tranny which I should have replaced the first time I was down there. Lesson learned. Was also having trouble shifting and really had to stomp on it in lower gears at lights. Even after using Dog Moly trasmission additive which apparently smooths shifting out on the Ks. Wondering now if it's just getting worn. So this spring I'll be heading back down the same path this time to open and inspect the tranny. Wish me luck.

Is it leaking oil or transmission fluid? The answer will tell you which seal is leaking.

Did you replace the O-ring when you did the rear main seal?

Good Luck...

Sorry for the two timer problem.

Good question, hard to tell because I use DogMoly Gear Additive so tranny oil is the same color as engine oil basically, might need a bright day to examine it closer. The leak is minimal only leaks after a ride. Replaced the O-ring.

Gear oil and motor oil smells quite differently.

Gear oil smells like sulfur.

It's definitely gear oil. Ordered two transmission seals and she's coming off again. Who's taken a transmission apart here, anything I should know about other than, don't drop it?

When I did the spline and RMS, I didn't want to mess with anymore seals than I already did.  I paid my local dealer to do the seals, I think it was 4 and a cover plate and bill came to $340 parts and labor.   I just dropped the gearbox there and picked it up after a few days.

I'm too cheap and I like the challenge plus the gearbox is a little clunkier than it was last year gives me an excuse to suss out other things :yes

Search "grub screw".

These transmissions are exactly the same as far as I know, perfect link thanks!

And by "grub screw" do you mean study the properties of it because there are many of these in a transmission? I'm elaborating to understand your point.

JamesInCA, I've spent a good deal of time on that thread you sent today. Some extremely good documentation of every detail thanks again for it. To do this properly, replace the seals AND any shot bearings which could be the cause of rough shifting, it would seem I'd need some factory specific tools. Soooo I could replace the seals for now, replace the seals and bearings or live with my slow leak or get a transmission with lower clicks. My feeling is that dropping it off at my mechanic is a hefty bill so that's not in the cards. Back to the shed...

The "grub screw" is what Americans would more often call a "set screw," and is the screw inside the transmission that holds the shift lever shaft in place with the rest of the shift mechanism. Apparently they have a tendency to come loose, and require an inordinate amount of work to reach in order to re-tighten. The symptom is slop in the shift lever.
