Hard to shift from 4 to 5th question??

[DREAMCOMETRUE]

this post is for a friend of mine. One of my good friend just got a super nice 03 Mach1. When he shift from 4th to 5th he has to be carful because it is grinching. He cant shift from 4 to 5 fast without hearing that noise.

Thanks for any help

There is a TSB on some of the gears. The synchros tend to go out pretty easy. I never had a problem with both of mine, but there is one out there. Go onto the reg. and look up TSB's. Also there are quite a few posts on there about shifting issues from 1-2 and 4-5
