what does it mean when the mechanic says that the oil is leaking into your transmission?
I agree completely with lugnutz59, there is no oil connection between the engine and transmission, it sounds to me like the mechanic is trying to take advantage of you.
If oil is leaking into the transmission then it means that the bell housing very well be cracked and the trans needs to be pulled and the bell housing needs to be worked on. If the trans is leaking oil then it could be a simple fix (oil pan gasket needs replaced etc.) What kind of car is and did you get a second opinion? This maybe a simple fix. Hope this helps. Roadog
I would really need more information to accurately help with this question, but I don't know of any way that (what I assume is) engine oil can get into a transmission. Yes, they are bolted together, but are two separate components. They do not share a common cooler, at least on any vehicle I've ever worked on, which would be the only way oil could be transferred. Oil may be leaking out the topside of your engine (like a valve cover gasket) and running down the outside of the transmission case, that is the only thing I can think of. However, if it's antifreeze that's getting into your transmission (automatic transmission only), then you have a defective radiator. The transmission cooler runs through the radiator to help cool the transmission fluid, and if the cooler cracks, it can allow antifreeze to get into the transmission fluid. If this is the case., the radiator needs replacement, and the transmission flushed.
What a bunch of educated idiots.
