Hi everyone,
I'd like to switch to AMSOIL Signature Series Synthetic Automatic Transmission Fluid (blue cap bottle) instead of Toyota's ATF WS fluid.
My question is how many quarts / liters of fluid do I need to buy to perform this flush? Can anyone chime in?
Thanks for your help.

I just had my transmission fluid replaced this past week by Lexus and I was told it was about 4L or 1 gallon.

Thanks SeanO,
Is your car 6 Speed manual or automatic? RWD or AWD?
I guess I'll contact my mechanic and ask him how much exactly is needed for this procedure. He says he does this regularly to a lot of taxi cars.
Thanks for your input man.

I flush my transmissions with 12 quarts of World Standard every 50k.

Why you guys are using the word 'flush' I'm assuming you're dropping the pan and changing that oil?

A full flush using the proper pumps would be a LOT more than 4 L

There are two methods:
Drain and fill shown in the video below and "flush" by using transmission exchange fluid machine.

My car is 6 speed auto and RWD.

My car had the fluid flushed - so it was pump in and pump out temperature controlled the entire process.

Have anyone see exactly where did tech hook up BG machine during flush ? My mechanic have BG machine, but he never done sealed transmission like 350, can't fing cooling line to attach it.

Depends on the dealer really. I think I paid about $300 at Lexus of Memphis.

Drain and fill is safe. ATW WS 1 Gallon is needed.

You should feel smoother downshifts. I do it whenever I start hearing hard shifts and they go away after fluid change. Usually every 30k miles. It is not synthetic and you must change it to maintain the transmission.
