I had Amsoil in everything (engine, diffs, tcase and tranny) up until just recently. Sadly, my tranny puked out a torque converter 3000 miles ago. Now, I don't know if Amsoil had anything to do with it but when I got her back I decided to wait at least 1K and then change ALL of it over to Mobil 1.SC-DMAX said:JimWilson, how do you like the Mobil 1 ATF? I have Mobil products in all other parts of my truck as well. Some have posted that the Mobil 1 in the tranny caused a temp INcrease and some slippage. I was wanting to swap over to the Syn ATF Mobil and am looking for your thoughts on the product.
