HAAS05

Just put RP synchromax in my 05 manual. Seems to have smoothed shifts a little. I remember someone having warrenty trouble with the Purple stuff. Well I'm past warrenty, but am wondering if anyone else has had any problems ?

I've been running synchromax in my tranny for well over a year. Shifting is a bit smoother, and no problems whatsoever.

well im glad at my job i have heard a customer talk about the RP fluid and FORD wouldnt warranty his tranny if he used it because its Considered to be an after market type "racing" fluid or something close to that but he did it anyways said it tightend yet smoothed shifts
