I have a 98 24 Valve 2500 that won't shift. When in drive she starts out in 3rd gear and stays there, she does not down shift or go into overdrive. I can manually shift into 1st and 2nd just fine. She has 130,000 miles and never had a problems up to this point. Any ideas on what the problem is?
Thanks for the HELP.
