30,000 on mine. No problems. Compliments my 4. 10 gears.
Their technical service has always been great when I had a question or two.
Mine was originally installed behind a 5 spd. and I pulled it out and installed behind my 2002 Automatic.
Gv sent instructions and parts that were needed for the conversion.
I've installed/deinstalled mine myself. Can do it in my sleep now.
I was surprised that the drive shaft is the same for the 5 spd. and the Auto.
I use the Mopar synthethic transmission fluid.
My 4. 10 Automatic in double OD would hit 140 mph at red-line if I had the horsepower, a tail wind, and a flat 5 mile stretch of road.
