Greasy transmission, should I be worried?

I'd get a second opinion to be sure unless you know those guys well enough not to stick it to you when the issue was really a valve cover gasket as mentioned. During my research prior to purchasing I don't think I even read about a rear main seal go bad but I'm sure they are out there. Nothing like the coolant system problems. I had valve cover gasket leak oil and it would smoke at the end of the off-ramp.

I've only seen two rear main seals that were bad.
Both vehicles had this weird groaning noise.
There was actually a vacuum leak through the rear main seal into the torque convertor cavity. I could feel engine vacuum at the transmission bell housing weep hole.

BTW. Thanks to Rover Range hanging around these forums. Having an actual JLR technician around is gold. GOLD!

I’ve had mine done when my trans blew. Wouldn’t even touch one unless you already have to remove the trans.

In another note, the D5 with the SCV6 that my parents have had to get one done at 30k miles under warranty, that one was probably just bad luck tho.

Couldn't agree more. GOLD!

I took some stuff off the front and I notice some greasiness in front - looks like valve cover may be it (left, driver's side). Doing a valve cover job should be a lot quicker/cheaper. Maybe even something I could tackle. More to come....

I have to do both of mine this summer and reseal my upper timing covers. The hard part is pulling the injectors and buying the tool to do so. Then since your pulling them you might as well get them cleaned.

How many miles did you get out of the tranny?

137k. The truck has been in California its whole life facing hills and mountains in hot heat, plus with 6000 pounds to push around and an AWD system putting more load on it, I wasn’t surprised.
