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.

This is my first time using this product, it seems to work pretty good, it's the same color of the antifreeze that I discarded and the product is so much cheaper than the Toyota antifreeze with the same ingredients and the same protection. Try it l thing you will agree! !!!!!!!!!!!!!!!.

I did a drain and fill on a GX460. I went ahead and replaced the radiator cap with this thing just because. I ended up losing about a quarter inch of fluid per few hours of operation. I put some tracer fluid in the tank thinking I had an actual leak, and the pattern made no sense for a normal leak at all. Accepting that there were no visible leaks (that made any sense), and the only other changed input was the cap, I replaced this cap with a factory OEM cap from Lexus. Went on an 8 hour drive. No coolant loss. If you need a radiator cap, then yeah get it. But I would not use it as a long term solution. Else, you will be perpetually topping off your radiator fluid (For a Lexus GX460 at least).

The gasket that comes with this set is cheap and not all one piece. The gasket that comes stock is much better quality, buy the flexpro gasket with this for an additional $25 and you won't be disappointed.

Replacing the factory MAF sensor with this one seems to have fixed some annoying issues such as; engine surging, delayed throttle response and poor MPG. Apparently this is fairly common with this generation of Corollas.
