Ok so I have had this truck for a little over a year. It only has 150,000 miles on it and is in relatively good shape mechanically. Today I noticed a new issue, from 50-65 it seems like it is almost slipping there is little to no fluctuation in RPMs and I don't really feel it other than a jump. The Trans fluid is clean and doesn't snell burnt but is about a quart low. I am curious if anyone else has run into this issue before and what the repair was.
