ISSUE
Some 2001 vehicles equipped with 4R100 transmission, having a transmission build date between 7/27/2000 and 3/23/2001, may exhibit an intermittent,
delayed or no second gear condition. Diagnostic Trouble Codes (DTC's) that may be set with this concern are P0781 (1-2 shift error), P0755 (shift
solenoid B malfunction) and P0756 (shift solenoid B performance). This may be caused by the Intermediate One Way Clutch (mechanical diode style)
not operating properly.
ACTION
Verify condition, follow normal diagnostics per the appropriate Workshop Manual. If diagnostics leads to the described condition, replace the
Intermediate One Way Clutch (OWC) (mechanical diode style 7A089), Intermediate Brake Drum (7D044) and Intermediate Clutch internally splined
friction plates (7B164). Refer to the following Service Procedure for details.
