What repairs have been performed to resolve the transmission problems you describe?My tranny isnt shuttering .It just seems to surge,Its like it not sure if it should go into another gear or not,around 40 mph
This may not necessarily been the transmission causing your concern. The transmission problems associated with the 42RLE are caused by the torque converter and there are no shared parts with the NAG1 in the 4.0L R/T. Even though this may be a similar concern the symptoms the 42RLE experiences cannot be applied to the NAG1 for diagnosis. :smileup:My R/T-2wd has a surge at 55mph with cruise engaged. When it started surging I downshifted to 4th with the selector and the surging did not stop. I upshifted to 5th then down again--surge still there. It is just like you are going up and down with your foot on the gas, but it is a mild surge.
