I have a 2000 cadillac seville with a 4t80e automatic transmission. My car stopped shifting into 5th gear at high speeds. It stays in 4th when maintaining my speed, or accelerating, and only shifts into 5th gear if I take my foot completely off the gas, or If i'm going downhill. I believe its the shift solenoids A& B, but I can't find any information saying if these are in charge of 5th gear, or if 5th gear is controlled by another solenoid that could be malfunctioning. Thank you

Tps is in charge of shifting. Otherwise the valve body is in control.

Are there any trans codes in the system?
