2000 GMC Sierra 4.8l 4L60E trans was slipping. It wasn’t wanting to go into overdrive and would occasionally bounce in and out of OD once it finally engaged.
Well, I took a 20 hour road trip (10 hours each way) and now the slip seems to be gone AND I feel as if I have better response time.
What happened?
Is this a sign of something really bad?
