Oil leak between the engine and transmission? The rear main seal is one of the places we check.
This seal sits at the back of the engine around the crankshaft, and when it starts leaking, engine oil can work its way down between the engine and transmission. The tricky part is getting to it — on most vehicles, the transmission has to come out before the seal is even accessible.
That’s why a proper diagnosis matters. You want to be sure the leak is actually coming from the rear main before doing this much work.
If you’re noticing oil spots under your vehicle or constantly having to top off the oil, bring it in and we’ll track down where it’s coming from.
