Dude, not to bash on you but you have to stop creating threads of the same topic. Is better to add questions to your previous thread problem related topic that way everyone who tries to answer your question(s) will have a better understanding of what's really going on.My 2003 Mustang GT has 90,000 miles on it and my synchros are starting to act up.. how long do you think i have before i MUST change the transmission.. and what would be a couple of choices of transmissions that i can upgrade to.. please if you have time, what upgrade would you make? and why? MY BABY COMES OUT OF THE SHOP TOMORROW!! AFTER 6 LONG WEEKS!!
