Causes and Fixes P0751 Code: Shift Solenoid “A” Performance/Stuck Off

How to fix P0751 Code: Shift Solenoid “A” Performance/Stuck Off
A P0751 code is set when the computer detects a problem with a transmission Shift Solenoid “A”. The pressure control solenoid regulates hydraulic pressure in response to throttle, engine RPM, and prevailing load requirements.
Fixing a transmission can be difficult since there are often many small components.
The most common cause of a A P0751 code is a bad Shift Solenoid “A” or the solenoid wiring but it can also be caused by low transmission fluid, dirty filter, transmission problems, and a bad computer.
Possible Causes of a P0751 Code:
Low/Dirty Transmission Fluid
Bad Shift Solenoid “A” or Wiring Issue
Transmission Issues (Pump - Valve Body - Blocked Passage)
Bad Computer (TCM/PCM)

Hi bro ! I fixed P0751 was bad PCM, but no code is given right now but I feel like slipping 2nd. I did everything - oil & filter, servo shaft extender, solenoid A&B replaced, accumulator test. But finaly fixed !! Any advice for my slipping 2nd ? Trans dropdown and rebuilt ?

Just changed the filter, and new fluid. Changed out both A and B solenoids. I need to check the fluid level again, but just took it 30 mins at around 45-60. Code popped up again. If fluid level is good what's your next area to look at?
