Just got my truck back from the body shop. I was in a front end collision and now it won't go into gear. I noticed when I first picked it up it was shifting hard then it got better now it won't go in gear. Could it be a coincidence that this just happened or could it be from the accident. Before the accident it shifted fine it didn't slip or anything. One other thing I noticed it happened 3 times when I was sitted at a stoplight I felt a bump like someone rolled into me the first time I thought I must have been imagining it cause the guy behind me didn't get out of his truck to check for damage. But it happen on 2 different times after that. I do have 140,000 miles on the original clutch. Any ideas?
