Should I Add The Lucas

[posey92]

Changing my manual fluid. I have mobile 1 full synthetic 7590. I was curious of what u guys thought of adding the lucas transmission addative with it...I know my second gear grinds a bit when ahifting into too quickly. Or should I just stick with the fluid alone.

stick with the oem recommended fluid. mine grinds a bit into 2nd as well.. usually when cold.. figured it's the synchros.. for now i go 1st to 3rd until op temp. i noticed it's nice if i lift the stick into 2nd slowly like you said..

I use bg synchroshift, works great. Although really you can use any 75-90 provided it doenst have sulfer, it will kill the brass synchros
