Rated 5 out of 5 by Felixthekat Excellent product
I use have been using Royal Purple products for all aspects of my vehicles for years so I am a bit biased but the sale at Pep Boys cannot be beat. Picked up 3 quarts for less than $40.00. Transmission has over 150,000 miles and it is still going strong.

Rated 5 out of 5 by captkev Worked as advertised
At 45,000 miles it was time to change the MTF in my 08 Mustang with a 5 speed tremec gearbox. I decided to try Royal Purple Synchromax instead of regular type F automatic trans. fluid. The Synchromax worked as it was advertised on the label. The transmission seemed to be quieter than before, but the biggest thing I noticed right away was the ease going through the gears. It was worth the few extra dollars over the conventional ATF.

Rated 5 out of 5 by Arow454 Love the product
I have a 1998 ford ranger with a 5 speed manual transmission and had original ATF instead of MTF and since switching to royral purple MTF for my transmission and my transfer case. I have noticed a major difference in the shifting speed and the way it feels to the transfer case running smoother for all my 4x4 advantures needs. All in all if you got Manual tranny you will love this stuff and done let the price scar you away because its well worth it.
