I have a 2001 Dodge Durango SLT with 100k on the engine and tranny. In last summer, i have come across an issue that i thought it was something to do with a transmission. My Durango's rpm seems to simultaneously jump/fluctuate when im going 50mph or faster and feels like the tranny is slipping. This often happens when I'm on the freeway. Since i couldn't diagnose the issue, so i took my car to a trusted shop. I was thinking that they could identify the issue without any problem, but they couldn't find the cause and i was also told that the transmission is still looking healthy. But the problem seems to worsen as i drove each day so i stopped driving my Durango. It's been a year since and now i need this car to run again so i could use it for my job. So if you guys could help me out and give me some information on how to diagnose and repair my Durango? and i need this car to run like new asap.
Thank You
