Tranny leak

[SRReality]

My tranny recently started leaking. It's an M21 4 speed, with a Hurst shifter. The rear seal appears good - - - that area is dry. The access plugs are tight, the speedo cable is tight and the side plate, etc. bolts are tight. The oil is mostly on the linkage rods and the lower end of the shifter assemble, but nothing appears to be loose there. There is what appears to be a sending unit of some kind (back-up light switch?) on the left side of the tranny. It wasn't any "oiler" than the stuff behind it, but the tranny is dry ahead of it and above it. The "sending unit" isn't hooked up, as this tranny is in a 62, with no back up lights. That thing would appear to be the culprit. Can it be replaced with the right sized bolt and washer?

Any thoughts on how to get the baked on oil stains off my exhaust pipes? It ain't purdy this way!

for the stains, not sure if it will work because I've never tried it, but what about a 3M Scrotchbrite pad with some brake cleaner?

I had a similar problem. Turned out my M-21 had no seals at all on the shifter shafts that go through the side cover. Sound like that's where your leak is originating. Maybe yours are worn out or missing like mine were.

Thanks for the idea............I'll try Acetone as well.

That surely could be! The last time I drove it, it left a little puddle about the diameter of a beer can, while sitting for just a minute or two, while I changed passengers. Until then, it leaked, but not very much at all.

I think I'll try the dye approach. With a black light, it shows up well, as I recall.

Are you one of the 'locals' down there (Rolla)?.

I graduated Jan. '71 from UMR. After a stint in the Army, I came back and finished up for my degree. Didn't hardly recognise the place, all the women. :W When I started fall of '63 there were 4000 men and 47 women. :ugh

I probably don't qualify as a "local" as I've only lived here 3 years. I think there's about 6500 students now at UMR. Your "story" parallels mine - - I graduated from college in Colorado in 1971 after 4.5 years in the Air Farce - - -crammed 4 years of college into 9 years, as it were!
