Does anyone have long term results information about using the GM Synchromesh stuff or Redline MTL instead of Honda MTF, preferrably in a racing or heavy track environment?

 

Well lately I've beat the hell outta my tranny racing it at the track (usually 20 1/4 runs each visit) and the GM stuff has still works really good for the environment I'm putting it through... I'll usually race 6-7 times per session before I give it a cool down time, then its back at it again... The events I race at usually have 4 sessions per event so... So far, I'll never use anything else in my tranny other than the GM Synchromesh.

 

If you go with Redline, don't forget the Redline LSD additive. You will screw up the LSD clutches if you don't! I don't know about the GM fluids, but the LSD is sensitive to the type of fluid you use in the 'tranny.
