There is a TSB out that provides a test for CDF bushing issues. Not being under any warranty would mean a diagnostic fee but at least it would give you some information.I'm at 84,000 miles. No extended warranty.
When i get to 3000 RPM, the 1 to 3 shift is smooth. All of the other gear shifts are normal. The gear hang between 5 and 7 only occurs when I first start driving and doesn't re-appear.Well, it looks like I'm going to have to take my truck and have it diagnosed. I'm having harsh shifting between 1st and 3rd and slipping between 5th and 7th. The slipping only occurs when I first start driving, but the 1 to 3 shift has become consistent. Putting into tow mode results in gear hang, same with sport mode.
