I'll be doing the ATF fluid change on my 722.3 after Thanksgiving. From previous reading on this forum, I know some have been happy with Valvoline MaxLife ATF.

Over on the Bob Is the Oil Guy ATF forum, there is some discussion that MaxLife had reformulated this year and dropped the viscosity to improve the product's match to modern transmissions. With some additional poking around, I found http://www.valvoline.com/pdf/Maxlife_ATF.pdf, a 7/6/2010 product sheet that lists a 100C viscosity of 6.11 cSt for MaxLife. My memory is that older data sheets (which I foolishly didn't archive) had MaxLife 19% higher in 100C viscosity ... 7.2ish cSt.

This reformulation seems to take it away from classic Dex III viscosity, leapfrogging to the low end (or below) of the certified 236.10, 236.12, and 236.14 fluids that are used for the 722.6 and newer transmissions.

Does anyone have experience with a MaxLife change in the 4-speed with the reformulated fluid? While the price and availability are right, I don't want to hurt a happy transmission.

Dex II was the original fluid. Castrol makes it.

Good Luck,

I'll check into it for you. The service shop that rebuilt my 400e transmission uses it. I will give them a call and find the source.
