Corvette with 8-speed auto has 6K miles on it, so I was thinking it might be a good idea to do a "flush" (not pressurized, just get the old out and put new in). I know there have been lots of problems with the 8L90 in these Vettes, but supposedly GM has it under control now with the new formulation of low viscosity ATF. Mine is a 2019, so it should have the new formulation already in it. Couple questions for this group. (1) Assuming I have the new formulation, should I just let it be and not change yet; if so, when would be a good time to change. (2) Are there any other LV options out there suitable for this application? (3) Is the Dexron HP (factory fill and replacement from GM) the same as the Mobil 1?
