carlasfxdl,
I had this same problem with my 1997 blazer, good and bad news for you. It had nothing to do with your trani, I had trani shops telling me that my transmission was going out and wanted me to have them rebuild it, however I knew better that that was not the problem.
Your problem, if it is the same as mine, is your wire harness in your steering column. I replaced that 2 years ago and have not had any problems since. kinda easy to replace.
If you have any questions feel free to e-mail me.
