My 96 Cobra has 132k miles. Under hard shifts, about 1 out of 5 times it'll grind and try to kick itself out of gear when going into second. It does fine at regular driving. A member of our local club rebuilds transmissions, he was at the track with me and said it's definitely the syncros. He said I could probably last a while before it completely goes, a good while if I take it easy on the shifts. He quoted $700-$900 for a rebuild. A friend of mine has a new edge GT he's building for the track. He's got the stock t45 that was completely rebuilt about 3k miles ago. He's selling for $500. I'd have to pay to have it installed. Which would you guys do? Thanks!
