68rfe Issue

Question

Looking for some assistance if anyone can point us in the right direction here.

I have a 2024 ram 3500 4x4 Diesel with the 68rfe transmission. I performed a transmission service and replaced the trans pan with an ats deep transmission pan. I installed all parts in the kit and now the transmission functions flawlessly from 1st gear to 3rd gear. When the truck tries to go into 4th gear I get p0734 4th gear ratio incorrect and p0933 pressure control solenoid b performance or electrical issue. Does anyone have any advice or ideas on what to do?
