There is a technical service bulletin describing what you said. TSB reference number 06-07-023E
A 1st to 2nd gear or 1-2 shift shudder at light to moderate acceleration meaning traveling a speed of 15-25mph described as a slip or delayed shift into 2nd gear.
If this description applies the TSB goes on to describe the repair which basically is tear down of the transmission and replacing the clutch pack (number 2 clutch pack) steel plates and friction plates and seals.
Any transmission tear down is going to cost a lot in labor.
If this doesn't apply does the automatic transmission fluid look foamy or strawberry shake in color?
Are there any check engine light or service engine light soon on? If so what are the codes?
