Vortec 350
Newbie
Hey I just bought a 1998 c2500 350 Vortec with 204,000 miles. I'm going through it and doing a bunch of maintenance and I was wondering about the trans fluid. I've heard horror stories that the fluid was changed and the trans started to slip because the clutches got used to the way that fluid was. I don't really know much about auto trannies so I thought I would ask. Also the trans was apparently "rebuilt" 100,000 miles ago according to the previous owner, but he couldn't prove it. Any thoughts? Thanks!
