I have a two part question my 96 Tahoe is making a kind of a grinding sound from the middle of my truck. My mechaniac said it sound like the tranny but it shift to good to me and ur only does in first gear. Now if it is my trans I found one on Craigslist for 300 I want to buy it and rebuild and slap it in there. I know the bolt pattern is different for different years could anybody point me in the right direction of what bolt pattern I need. Oh and also make that sound in reverse. Sorry more of a whining then grind.
