I purchased technical manual TM1743 07 June 04 online and cant seem to find fault code list. I have a fault code F393 ,F321 and F324. I noticed the harness plug on right side of TCU had been chewed by mice . I cleaned it up ordered pins and plugs to do plug replacement but not sure what tool I need to remove pins from harness plug.
After cleaning up plug I cleared codes and only F393 came back . Can someone tell me what that code is and what tools I need to remove pins.

Codes will be in section 9015, sub section 20 References, about 2/3 of the way into the list is labeled Transmission Diagnostic trouble codes and Calibration codes.

F393 - No Anti-Stall Hydrostatic Pump Speed Sensor
F321 - Transmission Shutdown
F324 - Transmission Shutdown

Can someone tell me what that code is and what tools I need to remove pins.

Don't remember off hand. Post a picture of the connector and the connector face (looking into the terminals).
