Looking for some expert advice. Took my tranny in and had it rebuilt, winter was a little cold so didn't get it put in until last month, it was leaking and broke my plastic shifter bushing on the test drive. I drove it back to the tranny shop shifting with my 12mm socket on a socket extension for them to fix the leak and clear the rtv out of the two rear shifter bolt holes. They called today and are telling me I have the wrong shifter. I've pulled a few at the junkyard looking for a plastic bushing and one that didn't have a broken ball in the shifter and they all 'looked' like the one I have, but I didn't take any measurements.
What are the chances that I have the wrong shifter or that there is something else going on? Basically the transmission keeps locking up and has to torn back down to fix whatever is getting locked up. Pretty sure they've pulled it twice now (glad I'm not paying for the labor). This last time he told me it locked up on a bench test.
Any help or feedback is greatly appreciated.
