| Attention: | It is recommended that a new 3-5-R piston and 3-5-R apply (waved) plate be installed any time the transmission is disassembled for any reason. |
- Slip or flare in reverse
- No reverse
- Slip or flare in third gear
- No third gear
- MIL illuminated, DTC P0776 is found as an active or a history code in TCM
This condition may be caused by a broken 3-5-R apply (waved) plate (507).
Important: It is recommended that a new 3-5-R piston (503) and 3-5-R apply (waved) plate (507) be installed any time the transmission is disassembled for any reason.
Important: Debris generated by the condition must be cleaned from the entire transmission and the pump fluid filter (203) and the control solenoid filter plate (8) must be replaced. These parts are included in the seal kit. Failure to separate the case halves, disassemble the transmission, clean the debris and replace the pump fluid filter and the control solenoid filter plate could lead to repeat transmission damage and repairs.
The notches in the 3-5-R piston (502), as shown in the photo below, were removed during the 2011 model year. Be sure to replace any 3-5-R piston with notches when repairing a broken 3-5-R apply (waved) plate or anytime the transmission is disassembled for service.
