Attention: TDR Forum Junkies Just completed my first tow w/my 12K#fiver and it was a great tow. About 360 miles over mountainous terrain and I averaged 11. 5 mpg. Almost 4K miles on truck. Only thing I didn't like is the 48re xmission would not shift into overdrive unless I let off the go peddle and sometimes when it did shift into overdrive there was shudder,vibration somewhere around the exhust pipe heat shield, anyone have any thoughts on that?
