I have a 2011 LR4 HSE V8 (85K miles) (w/Tow Package).

It threw a transmission fault yesterday after switching to sport mode on the highway. I was traveling about 65 mph when I switched it sport mode and the car thudded fwd twice and trans fault light came on. I pulled it over to a rest stop within 1 mile and had a look. Immediately, I noticed a smell and proceeded to see good leak underneath the car. I thought it was tranny fluid and decided to have the car flat bedded to a local repair shop I've used before. Today the shop called and said the fault code is saying there is an issue between gears three/four. They can't fix it and want to send it to a trans shop. Most likely needs to be rebuilt according to shop.

Ideas? Does it make sense to try a transmission flush with new filter/oil before going to a trans shop?

They also quoted me $1100 to fix the leak as he says it from a coolant line/box that runs to the engine. I thought that was odd as the car has not leaked coolant and has not had a problem until the transmission thud yesterday. It was leaking pretty good when I pulled over and was sure it was tranny fluid (sorry, novice). He looked at it a second time after my questions and came back again that it was coolant. Is it possible that the trans issue caused the coolant line issue, or am I getting a run around? Again, the car has not leaked anything until the tranny issue. Only recent work (Aug) was a new seal on the gas tank recently. They had to drop the tank and replace the seal. This was done after a overwhelming smell of gas was found.

Any help is appreciated. Thank you very much.

If it was transmission fluid, it will probably still be there on the ground where it was leaking. If it was coolant, it will probably be gone.

Did it smell sweet?

Yes, faintly sweet. I disregarded it as coolant as the truck had the transmission issue (thud fwd twice and fault). Color was orange/brownish/black. I know the coolant is orange and also the tranny fluid (I think). I'm just baffled how the coolant issue could arise from the trans issue. Any ideas?

I had a transmission fluid leak and mine turned out to be a $20 part, Part# TZV500010. Luckily, I still had extended warranty. It would have cost $1500 in labor. My service advisor said, "It's a very common problem." Not something I wanted to hear, but it solved my issue.

Good luck...
