Oh so the rpm goes up... I thought your engine lack of power. So don't mind what I said about pump, EGR, DPFE... etc. It's a transmission problem.
It's seem that the problem is either the clutch pack, clutch bands or servos for gear sets of 4th gear.
The "3-4 shift valve solenoid" shifts the trans from 3th to 4th gear by opening an integrated valve that allow trans fluid to activate the clutch pack.
If clutch pack is not working, it's like if you were in neutral.
If you drive with O/D off, it still slowing down? The O/D off light is still on your dashboard?
When the PCM (computer) detects the transmission problem, it prevents the trans to shift until you stop.
Your engine code can tell you if you have a trans solenoid problem, but you need a high tech OBD reader to scan trans codes.
Or, you still have an issue with your TRS. Maybe the alignment is still incorrect.
