engine and drivetrain transmission leak

[sweitzer]

So I recently completed a five speed transmission conversion on my 2002 and then proceeded to drive it almost all the way across the country. The only problem that arose was a leaking of transmission fluid which appears to be coming from the shift leaver or drive shaft output because both of those parts have this fluid on them and the fluid appears to only be toward the rear of the transmission. I did not put in two seals, for the shift lever and drive shaft output, that came with the kit because I had installed them on a different transmission before i discovered that it would not fit, and subsequently could not remove them. Is there anything else that could be leaking and does anyone know where i could find those seals?

My 4-speed leaks at the rear casing joint. Redline MTL makes it worse. What type of lubricant are you using?

Those seals should be readily available, I replaced some about two years back.

Remember, there is a lock thing that has to be removed to replace the output seal, It is hard to see sometime. That lock thing even keeps the big nut from coming loose. Use a new one on install.

Sometimes transmission fluid comes from the shift tower block bolts.

I replaced a bunch of gaskets in my 4 spd, and the fluid seems to coming out of the bolts for the shift tower, as previously stated.

I recently had my getreg 245/5 leak through the splies on the output shaft. I used high temperature Loctite "white loctite" and it stoped leaking.

Leaking through the shift selector rod seal is VERY common. You say you haven't changed the seal. This one isn't too bad to change with the trani in the car. You'll probably need to pull the driveshaft to get good access. Then pull the shift lever and the extension to the back of the shift selector rod. You can pull out the seal with a hooked seal puller you can buy at Sears or at any auto parts store. They sell the seal at any number of places including www.bavauto.com. The quick and dirty thing to do is not to pull the old seal at all and just use a new seal to push the old one further in, but I've gotten pretty good at pulling them so I just do it.

For the output shaft seal, you don't need the puller shown in the other post; you can unbolt the flange that the seal sits in, and then just bang it out from the other side. Be sure to order a gasket if you're doing it this way.

Of the two, I think that the selector rod seal is the more likely culprit.

Thanks for all the advice, I'm gonna put in a new selector rod seal and check the mounting block bolts this weekend and see if the fixes it.
