Truck is a 2019 2500 Big Horn, Crew Cab, Long Bed with the 6.7L and the 48RE transmission. Truck has just over 30K on it today. The issue I am having with the truck is rough shifting and the transmission when driving with the truck in normal shift (D) and not using tow mode or limiter switches. The truck will shift so fast up, but hangs on to the gear going down. For example I can be driving through a 20 mph school zone, and I approach the school zone the truck will start lugging through the zone, and I will almost have to stop to get it to downshift to a gear that allows the truck to idle through the zone. Also, once I do get the truck down to a better gear, if I idle along the truck will actually shift up again when going just over 1100 rpm or so and right back to lugging again.
In this one community I travel through I need to slow to 35 mph, and then the zone will increase up a slight upgrade to 45 mph zone. The truck will shift down to a point where I am travelling 35 at about 1100 rpm, and then once I hit the 45 zone I want to increase speed the truck is lugging. If I want the truck to down shift, I have to depress the pedal so far and then once the truck does downshift the engine jumps up in RPM to like 25-2800 rpm.
I feel like the truck is not shifting right. Up shifts are way to fast, and then the truck likes to hang onto the gear. The truck had the valve body work done per a recall, and I have had the truck in the shop three times now for this fault. The first time they put the transmission into relearn mode, and it shifted better for two days, then right back to the same old way of shifting badly. The second time the truck was in the shop told me that there was an update that was applied, and once again it shifted okay for about two days and right back to shifting badly. Third time the truck was in, I was told that the truck was running an incorrect software update and had to be corrected. Again, the truck shifted okay for about 2-3 days and then right back to shifting badly.
Is it me? Is anyone else having trouble like this? I need to take the truck back again, and this time in the notes I got from the dealer, they need to escalate the case. I have to keep taking time off from work, and get a ride, and drop off/lose the truck for a day, and as this all happens I am getting closer to that 36 bumper to bumper warranty, when things might change in the way the dealer is working with me now.
