My MGW should be here tomorrow, so hopefully over the weekend I'll be installing it and changing the tranny fluid while I'm at it. I have the RP Synchromax already, but does anyone know about how many bottles it should take?

Thanks! I've heard of people filling from the top while they have the shifter out. Is that ok or should I just use the fill plug?

 

DO NOT fill to top with shifter off !!!!!!!!!!!!!!!!

 

The only thing I would suggest against is using that Synchromax. The synthetic can wear the syncros prematurely in these trannys. Many people who switch to a standard Mercon III from a synthetic, comment on how much easier and smoother the shifting is.

 

i just realized that u said fill "from"the top and not "to" the top................filling from the top is ok just dont overfill
