Transmission Leak

[KVH]

I really don't want to pull the TR4A tranny out just yet. That means seats out, dash apart, carpet out, etc.

Question: I see gear oil on underside and the rear part of the transmission, but I can't detect much back near the rear seal. I assume that's where it's coming from, though.

Maybe I just overfill it all the time. I checked it after about 5000 miles and found the level at the bottom of my pinky finger just about 1 to .5 inches below the filler hole, so I added more.

If I reach any fluid, say even an 1.5 inches below the filler hole, is there enough or does it need to be hovering right the filler hole level? (Because it sure isn't)

I assume a slow leak is normal in these cars?

Do they ever fix themselves? Hope. Hope.

Thanks, all.

I doubt that you over filled it. If you clean the tranny up and take it for short drives; after several miles, crawl under and inspect.
The only way it will fix itself from leaking is if you let it run dry.
I fill the unit until it begins to drip out the filler hole.

To quote some other Triumph owners on this forum, Triumphs don't leak oil. They are just marking their territory.

Don, I have a question for you since you've had your car from new. Were you the first to tear down your gearbox (if in fact it ever has)and if so did the gaskets appear to have gasket cement or not. I've had other people tell me that they thought the gearboxes were assembled without it. Although I bought my car from the original purchaser in '68 I swapped boxes without ever having torn the four speed down.
