I have had this happen a few times now. THe first time I was pulling my 24 foot gooseneck with a truck on it crossing a 4 lane highway. When I take off as the tranny is about to go into 2nd gear and I am right at 2K RPMS I lose ALL power. It is like the motor shuts off for about 3 seconds. Then when it kicks back on the exhaust is really deep and it takes off like normal. It has done this about 5 times now and it is always at 2K RPMS right before it shifts into 2nd gear. It has never done it at higher speeds. I do know I need to change the fuel filter but I would think if the filter was the problem it would be doing it at other speeds especially when I am pulling a load and going up a steep hill.

 

Some other experts will be along soon, but I bet it is something in the tranny like the TQ slipping or a governor valve issue. You may be starting out in second and it drops like that trying to lock in the TQ.

 

I know that it is for sure starting out in first gear. I can tell that much. It did it a few times today and everytime it would hold first gear until 2K RPMs and then when it goes to 2nd it takes about 3 seconds to get into gear. But also what is weird is when I am between gears I cant rev up the motor. The RPMS just slowly drop until it takes off.

 

48RE Transmission - 1-2 Shift Hunt At Light Throttle
This bulletin involves the replacement of the governor pressure solenoid valve in the transmission valve body. TSB 21-009-07

 

I already knew that and I have told the dealership it is doing that but they couldnt ever get it to do it. I have had 3 dodges that have done that and the governor pressure soldenoid and switch replacement always takes care of it. The new problem isnt gear hunting it is just taking a few seconds to get into 2nd gear.

I did take it to the dealership today and they checked it out this morning and said I had a erratic speed sensor messed up.

 

what if you shift it manually? does it do it at all? I would try that a couple times if you haven't already

 

had the same problem with my 99 would go til 45 then just hang there sometimes would change gears other times just rev was governor pressure solenoid in mine cost me $250 to have it replaced

was told it was starting in 3rd
