has anyone used this product in the light duty segement. I was wondering if I could use this my 115k 4t65e that has had mobil1 atf since 30k, just wondering if it would offer any better protection/ longevity to the transmission
The question is if you'd be able to measure a performance difference in a properly maintained transmission when comparing ATD to M1. Probably not. Another coin toss!
I would recommend upgrading the filtration. This is where you will see a difference in longevity. My belief with automatics is have good filtration in place and flush the fluid every 30-50K. M1 is a great ATF as is ATD. I don't think you are going to see a difference in this application between the two fluids as has already been stated.
Pick a fluid and stick with it along with a reasonable OCI. If you want to try a new fluid for [censored] and grins, then I would just get the Amsoil ATF. More than adequate for your projected use.
well, I was just looking for something that would offer a higher level of protection since this trans is over 100k, still shifts perfect and the fluid is still clear after 50k miles of service with the mobil1 atf
