The right stuff!

I have used Valvoline products for over 50 years and find them to be of the highest quality. Regular vehicle maintenance and no abuse and Valvoline won't let you down. Being Ford no longer supplies Dexron II of III nor Mercon ATF fluid I have to go aftermarket and find Valvoline to be great choice. Sure I can spend two or three times as much for other brands but I would still change it on the vehicle manufactures schedules. In that case Valvoline does the job for me and I have never had a problem related to the ATF fluid.

A Decent Value for Dexron III.

For Dexron III or Mercon applications it's a good value on a semi synthetic fluid. It's not a full synthetic fluid like Dexron VI or Mercon LV and is just fine for non extreme duty 30K mile change intervals. Older transmissions like 4L60, 4L80, AOD, and E4OD unit's work just fine on Dexron III fluids.

2004 2500HD 6.0 4L80 transmission fluid change

I used this Valvoline Dex/Merc transmission fluid/filter change in my 2004 Chevy 2500HD 6.0 4L80 transmission. Worked great. This is considered Dextron 3 and that is what my 4L80 transmission came with new. No issues at all, shifts great after the fluid change.
