I was thinking the mopar stuff was a semi-syn but I'm not 100% on that. Synthetics have definitely shown their advantage in the drive train. Hence factory fills are becoming commonplace.

That's all I run. Never had a problem. Have a 15,000 fifth wheel I haul in the summer. Like the fact that I never run over 200 degrees, even when it's 100 degrees outside!

Genuine Mopar is the only way I do retro fits of 500 & 518 trannys into old school Mopars & that's the only way to fly. After 75K or so remove completely or remove & replace the check valves in the hoses at your radiator & flush the cooler. These check valves are a leading cause of OD failure. They hold trash like crazy & somtimes when you change fluid the fresh fluid dislodges what I call a blood clot of trash. When you remove these it will hesitate going into gear when parked on a incline they are anti drain back valves Bob
