GM Synchromesh and warranty

915 Views 13 Replies 9 Participants Last post by  Walkman003309
I was about to swap to the Synchromesh in my transmission and discussed it with my brother who used to be a Ford mechanic. He brought up the issue of whether it would void the transmission warranty should Ford release a TSB. What do you guys think? What about the ones that have already done this. I have the Tri-Ax installed after this past weekend and the Synchromesh was my next step. I asked him how would Ford know? Neither of us have ever seen the stuff, so I don't know if there's a noticeable difference or not.

Thanks for the input, guys. I'm running Valvoline synthetic oil in #3618 and since that's where I get my oil changed, I was going to let them install the Synchromesh that I was going to pick up at the Chevy dealer. But if you guys think the Valvoline synthetic ATF has just as smooth results and is obviously a lot cheaper than $9.42/qt. then I may just let them do the entire job.
