Excellent ATF for Buick 4T65-E transmission
Excellent ATF for Buick 4T65-E transmission
Submitted 2022-04-06
By John in MD
From Baltimore, MD
My 2001 Century started having hard shifts at around 135k miles. I dropped the pan, replaced the filter, and refilled with about 7 quarts of Valvoline MaxLife ATF. I also added in 11 oz of BG ATC (automatic transmission conditioner). What a difference! My car now shifts smoothly and solidly. Maybe I didn't even need the BG ATC? All I know is it now runs like when it was new!

The ATF is being used in a 2004 TB 4.2 L engine with the 4L60 transmission. This SUV requires DEXRON III and manufacturer has updated and aproved the DEXRON VI. This is a high mileage (170k) transmission that I rebuilt at 85K with new reinforced SHELL, Bendix clutches, high volume pump and all new solenoids. ATF total capacity is 11.4 quarts including 1 quart (64 oz) of LUCAS ATF additive on every scheduled change at 50k miles, filter and gasket included. Works fine with smooth shift at all temperatures, with or w/o 4x4, specially when towing my boat trailer.
