Tranny leak stop
I have a 98 A4 and a 99 MN6 and my 98 A4 had a slight leak out of the rear of the tranny, i put a bottle of Lucas tranny leak stop in and I'ts been great since not a drop. My 99 MN6 has a leak at the rear of tranny right where it meets the differential? i think it is? but i wanted to try the same thing using a bottle a Lucas in it before i pulled the rear out b/c if that works then that will save me a lot of aggravation. Anyone know If i can use Lucas in a manual? if it's safe to use???

About you manual car:
I had same problem leak between diff.and trans
My leak was at the transmission extension housing where the diff and trans meet. At that seam line there`s no gasket it is silicone...so putting a stop leak additive in your trans won`t do any good.
I had it fixed with $1080 at a dealer and had the diff resealed at the same time on that price.
Dry as a bone now

MN6 to Differential Sealant failure/fix, DIYer
Somewhere on this Forum a member posted how to CHEAPLY fix sealant failure (it's not a gasket) between the MN6 and differential. He built a tube adapter to attach his shop vac to the transmission, seperated the transmission from the differential and used the shop vac to establish a vacumn in the transmission and 'pull' in new sealant into the joint. Torqued down the bolts after applying the sealant and no more leak. Cost was for sealant and plumbing parts for the adapter tube, not hundreds or thousands from the dealer. I can't find his post. Hopefully some one will pipe in.

Holy nuts- it cost over $1000 to do the fix? Well, mine was also leaking I fixed it on my own by removing the rear suspension and lowering the transmission/rear/torque tube.

I fixed this (short term) on my 01 Z06 untill I get my detached garage finished and can properly fix during a clutch upgrade.
Drain your tranny, clean the case at the seam where it's leaking with a rag and carb cleaner. Get it dry and clean. Apply a fairly large bead of silicone RTV to the outside of the seam, make sure to cover it well. Allow time to cure (24 hrs) and refill. This totally fixed the leak on my 01. Ideal? Nope. It's a short term temp fix, but it works, and it cost a couple of bucks.
