I just dropped my transmission pan, changed the filter/gasket, and changed the differential fluid (after running Seafoam Transtune for 1 1/2 days) in my '93 Lexus ES300, with Quaker State Fully Synthetic ATF. I had been using Valvoline Maxlife, but my shifts were continually getting rougher and rougher. So I read that synthetic ATF is supposed smooth your shifting. All I can say is WOW! It's never shifted that smooth since I've owned it. I do need to get 1 more quart of this stuff and add between 1/4 to 1/2 quart more to my tranny fluid. So far so good!
And yes this is Quaker State Fully Synthetic, not the Synthetic Blend. They do not have it up on their site, but it can be found in some O'reilly's Auto Parts Stores.
