I haven't really been a fan of how my '22 2500 ( with 10k miles on it) shifts, especially on the highway. Talking primarily unloaded, or with up to 1500lb weight in the bed, but not towing here. First off, it really likes to drop from 6th to 5th when accelerating, when it really doesn't feel like it needs to. For example, if I am in 6th going ~70, and move to the passing lane and try to accelerate to 75 or 80, it will drop down to 5th. In the process, the torque converter unlocks, the engine speed flares up to the high 2000's for 2-3 seconds as the torque converter slips, then eventually settles back down to about 400-500RPM below the max RPM it achieved during the shift.
Is this normal? It seems excessive to me. I have heard some shift flare is normal with the 68RFE, but when it revs like that, it makes me want to take my foot off the accelerator - feels like that much slipping can't be good for the transmission. Thoughts?
