I have a 2013 Jeep Wrangler Unlimited Sport with the 3.6l engine, automatic transmission and it has 90,000 miles.

I have an issue that only happens the first time I start for the day and put it into REVERSE. After I drive for a while I no longer have the issue and the transmission seems to shift just fine. Performance is normal.

The scenario: I start the engine for the first time that day and let the idle settle. I put the transmission in REVERSE and it will bog and nearly (sometimes does) stall the engine. The only way I have been getting around this is to first put it in DRIVE for a few seconds then into REVERSE and it doesn't do it as much but it sure "pulls" hard into gear.

The odd thing is that once I start driving it seems just fine with normal performance for the rest of the day.

I took it to the dealership for this issue and they "flashed the TCU?" and did a transmissions fluid service. None of that helped, I still have the same problem. I'm hesitant to take it back to the dealership for obvious reasons.

I really hate this because the engine just purrs at idle, pulls strong and is just running great for 90k miles.

Any advice would be greatly appreciated.

Jody.
