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.

I have used Valvoline engine oils since I owned my first car when I was 18. Before that my old man has used it since as long as I can remember. I have gone from Maxlife blend in my older higher mileage cars (88 Dodge Caravan and 96 Hyundai Accent) to SynPower, now known as Advanced Full Synthetic in my newer cars (2009 Suzuki SX4, 2016 Toyota Rav4, and 2022 Cadillac XT5). In all my years of using these oils my engines have always ran like the day I have taken the car home brand new with never any issues related to the engines themselves regardless of the engine manufacturer. This oil has advanced well throughout the years getting better and better and has always done a phenomenal job in maintaining the reliability in all my car engines. I give my car oil changes every 6 months before the extreme seasons of winter and summer so they have a fresh batch for the coldest and hottest days. Best protection for extreme temperatures. I also started using other Valvoline lubricants for other components like the differentials for the AWD system and the transmission fluid. Valvoline is a safe bet and among the best of the best you can give your beloved workhorse.
