Thats not a rear main seal... thats a tail shaft seal or extention housing seal. The rear main seal is the seal between the motor and the trans.

If you had a rear main seal leak you would have leakage from the middle of your bellhousing and the engine. Plus with a rear main seal on a M6 you would probably have some clutch slipping due to the motor oil soaking the clutch.

You could probably have that seal replaced by the dealer or a local shop for less then a couple hundred bucks installed. Or do it yourself if your slightly mechanically inclined, its not that hard to replace.

It's not hard to replace, but it is easy to mess up...

The tail shaft seal is easy fix. Pull driveshaft and with a srew driver pry it out and replace. Simple fix. Haven't really seen one just go out all of the sudden though. usually start slow and get worse.

Pull it apart & inspect the bushing once the seal is out.
If all looks well put it back together. Get a can of brake clean or the like & clean the area up. test drive & recheck it for leaks.

prolly just the rear tranny seal but the smoke from the rear could be bad or nothing to worry about though. it could simply be the tranny fluid burning up on the hot exhaust pipe. but hope that its just tranny fluid cause it cant be good if smoke is coming from tranny.

well then there is nothing to worry about. it is probly just that tail shaft seal on the back of the tranny. shouldnt be alot of money to do yourself and seems like an easy fix. just take the four bolts off of the ujoint and pull the driveshaft off and out of the tranny then take the old seal out and put the new one in. no biggy.

my rear main seal just went out on my T/A and i burned up a 400 dollar clutch in like 3k miles because the oil that saturated the disc. it really sucked.

I hate to be the one to say something else, but I had this happen to me(auto) racing on the highway the trans puked fluid everywhere. Determined that the trans overheated, fluid expansion caused alot of it to be spit out the vent tube.
Just another thing to check out.

I squeezed that seal that the driveshaft goes in and fluid came out of tere so im guessing that its the tailshaft seal ...from the outside it doesnt look there is any wear on the seal though is that odd?

That's not a seal, it's a dust boot. The seal is forward of that, and you won't be able to see it until the DS is out.
