Any one run royal purple tranny fluid?

ive changed my front diff, rear diff, transfer case, and engine oil all over to royal purple....but im curious if anyone is running royal purples ATF, i hear tacoma transmissions are sort of finicky with what you put in

oh and i have a automatic dc trd off road

 

I would stick with what Toyota Recommends.

 

I don't see why not, Royal Purple is good stuff. I drive a manual tranny so can't help you there, but it should say on the bottle what brands it is good for.

 

This.

Toyota T-IV or WS... depending on whether you have a 4spd or 5spd.

Personally, I like Mobil-1 and Amsoil products, and I ran Amsoil Torque-Drive in my '06 Duramax's Allison, but I won't put anything but Toyota fluid in my Tacoma trans.

 

I wouldn't run royal purple in anything, but that's just me.

Stick with what toyota designed to be ran in the transmission.

 

whats your reasoning?

 

I and a friend are running with it. Mine in my Taco and the friend in a Diesel truck 15qt and he has increased his MPG by 3 miles. We both swear by the product.

 

Amsoil has an excellent WS-compatible transmission fluid for automatics - I've ran it with absolutely no issues in my TRD DCLB. Never used RP fluid before, but if RP has a WS-compatible offering, I don't see why it would cause a problem.

 

Oh I don't use it in my Transmission but in everything else
