Transmission fluid

What’s everyone’s pick for transmission fluid and how many quarts do you go through on a change?

 

Valvoline MaxLife ATF. ~13 qts on hand if doing a DIY full replacement; ~3 qts if doing a simple trans pan drain and fill.

 

I used Idemitsu TLS-LV. It is a synthetic WS fluid. Full replacement.

 

A reminder, stick with same fluid that is already in the transmission if doing a drain/refill. If doing a full flush, you can put in any WS compatible ATF. Maxlife is a popular option due to it’s affordable price and wide compatibility - it can also replace Type-IV ATF which was used before WS.

 

I think I'll try that next. Looks like they sell it in a 5qt jug for ~$40 which is on par with Toyota WS.
