Has anyone experienced a shift hesitation/drop inRPMfrom 1st to 2nd gear at about 20 MPH ? Seems to happen more when you try to accelerate quickly from a stop, but also sometimes when just accelerating normal. Dealer told me this is normal (I have an '07 Hemi QC) but it seems not right to me and even a bit dangerous if trying to get out into traffic. I have had a drop in RPM at higher speeds (50) and attributed this to MDS. Drive with OD off, which helps at higher speeds, but still have the hesitation at lower speed.

 

i just recently had this problem with my 05. Took it into the dealer and they did tons of test and found nothing, wasnt throwing any codes, so they said i probly need a transmision service since i hadnt had one yet and truck has 75k on it already, so did that, 300 bucks later its the same and so then they tell me that its because i have oversized tires on, so i put my stock rims and tires on there and still the same, sooo took it back again and they did more tests and turned out to be a preasure valve in the transmision wasnt working, replaced that and all is fine now, maybe get them to check that out

 

Thanks. I'll try that. I only have 8 K on it but this has been happening since I got the truck. I notice it more since I put a K&N and new muffler on it. Probably more because of the sound though than the problem getting worse.
