GM Synchromesh and warranty

914 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.
