I have a 2009 Vibe 1.8 FWD with the 5-speed manual. At 136k miles, the input shaft bearing in the transmission went (got real noisy). So, I had it rebuilt at a local shop. The owner said they replaced all the bearings plus a few synchros.
It worked great for about 4k miles...shifting was awesome with Redline synthetic fluid. Then one day it started popping out of reverse randomly, and then got stuck in reverse! The shifter and clutch work fine...when I put the stick in 1-5, the car stalls when I let out the clutch. When in neutral, letting out the clutch results in the car going backwards. When the stick is in reverse, the car goes backwards like it should. I checked the shift cables and everything is connected and moving like it should.
What do you all think? Messed up reverse gear shift fork inside the transmission is my guess...the shop is refusing to honor their rebuild warranty and is telling me that nothing they did would have affected this part of the transmission. Is that true? I thought it all had to come apart to do bearings...including removing the shift shafts.
