Have them check the transmission dipstick tube seal for leaking.
 
Hello Guys:
On the last holiday trip, 6oo km, towing a small trailer of 400 kg, on a slope on the road, appeared the signal to "check gauges", because the water temperature went up. Soon, the slope on the road are over and the low temperature are over too. On the next slope he came back out and I stopped to let the temperature drop. There were no more problems throughout the trip. The car worked perfectly. No problem in gears.
Three days after, after a 30 km journey, when parking, oil appeared from the gearbox on the ground, which came from the front of the converter housing. The level at that time was at the minimum mark although the car was not horizontal, but on an uphill slope. Wiht the engine hot,
Before starting the holiday trip, I checked that the level in cold and flat was above the maximum.
I have learned now how to check the level, after all this. Hot and flat.
In the Jeep workshop, they changed some seals and the oil pump, but the problem was not in those parts because the problem persists. The car is still in the Jeep workhouse.
I remember to have seen a lot of months ago, a lonely oil drop once under the transmission.
The breakdown must have been due to the increase in water temperature?
Due to trailer towing ?. It's the first time since I have it, It tow a trailer.
Any ideas or suggestions?.
 
I doubt that this leak was the result of towing, it's more than likely just a coincidence.

However, the area you're saying that it's dripping from, that's a very common area for either the rear of the valve cover gasket to leak down to, or the rear main seal.

Is the fluid you're seeing on the ground automatic transmission fluid (which would be a reddish color), or is it engine oil?
 
The leak appears in the left side of the low joint of the cover of the converter, part number 21. Yes, it is red oil fluid. I dont know if they have checked the leak in the 2 and 4 part numbers (level tube and o-ring), but in the image seem this tube is in the other side of the converter housing. The leak came from the case, part number 5, the "bell".
I also think that it is a coincidence, in fact the leak appeared already three days ago that I did not tow the trailer. The fact that the temperature rose on a hill dragging the trailer is something that I did not surprise me because in this forum I had already read that this could happen, and that when the towing is a normal job, it was commented to add a cooler special to compensate for the overheating. It was also on a hot day and it was 13 hours or so.
