T-5 Trans Gone Bad...

[Chevyguy]

What happened is you were not completely in first, then it popped out. That is not necessarly a death sentance yet. My old trans would pop out of second sometimes while driving, that syncro was shot as it would often grind downshifting from 3 to 2. Eventually the 3rd cluster gear broke apart. That trans was rebuilt by a local trans shop, and only lasted 40,000 miles but always shifted funny and never really felt right.

Poor adjustment of the clutch cable, or firewall flex can make it hard to fully shift into a gear, look for the cheap stuff first
