I've run Type F in all my mopar transmissions and never had a problem. Even hooked up a trans temp gauge
and never ran hot. It's all in the trans coolers I use evidently. I always bypass the radiator.
Well, I would guess that if you ran 1000 trannies hard for 100,000+ miles, and half had synthetic, and half
had dino juice, you would see fewer problems with those with synthetics. Simply due to synthetics
lubricating better and lowering operating temperatures. The number one killer of trannys is heat. But each to his own, as we have been going
back and forth on this issue for years. Run what'ya brung!
