Hello, just put in a rebuilt 5spd, 230,000mi, one month ago. I was assured there was a fully splined shaft. This morning the shifter would not not move into the 5th gear position. After some wiggling of the shifter got it into the 5th gear position but it is as if there is no gear there. Can someone explain what may have happened? I do not have a good idea or picture in my head of the problem and fix. I hope it is under warranty and still do not look forward to the labor involved. Can it be approached while still in the vehicle by removing the transfer case? 4wd, '96. Thanks, Steve
