Leaking gear oil/transmission lube Source?

[nick_g_evans]

So my transmission is leaking some red gear oil and I'm not sure of the source. It looks like it's just coming from the drain plug, but I don't know why it would do that as it's bolted in. What could be the source of this leak? Rear main seal?

Try to clean the tranny with Gunk or its like, then drive a few miles and take another look. You should be able to see where it's leaking from. But it sounds like a seal.

It's the seal. Once it's bolted in if it still leaks you should get really bad smells in your interior. The oil leaks onto the exhaust pipe and burns up. The seal is relatively cheap, the labour is very expensive. It's a lot of work to replace those seals.

Are you guys talking about the selector shaft seal or the rear main seal or something else?

this is the same thing my 95 325 is doing. tranny oil leaks onto the exhaust, its actually at the dealer now waiting for me to pick it up, they inspected it and said it needed all new tranny seals and that they would need to drop the tranny (i dont believe this) and that it would be $1600 in labor. ive looked at it even replaced the pan seal myself a few months ago and it only looks like its leaking in that 1 spot where it drips down on to the exhaust.

im taking it to another shop to get a second opinion tommorrow. hopefully the entire trans doesnt need to be dropped and resealed : (

Unfortunately it is really expensive to fix. I think $1600 is a little excessive though. However, unless you know someone who can fix your car cheap, I think you're stuck with the bill.

You guys are a bunch of pansies. jk I'll just drop it myself. Are the seals expensive? I guess I'll do my clutch now too.

Seals are cheap. I'll try to get you the exact part number tonight from the BMW ETK disc.

Well, I am just going to have it done. I found out it was the output seal and the shifter seal. The total was $380. That includes 3.5 hours of labor. They don't have to drop the whole transmission, just half drop it.
