information in VIDA.
Valve Body: The Valve Body should be replaced to address the following symptoms:
1.
Customer complaints about 2-3 upshift quality. The shift may be described as harsh, or as a shudder. The symptom is usually more apparent during
the first few minutes of driving after a cold start.
2.
Customer complaints of shudder when slowing down, just before coming to a stop. The symptom may also be described as a harsh downshift just
before coming to a stop.
3.
Neutral condition in 4th, 5th & 6th gear; normal behavior in 1st, 2nd, 3rd & Reverse. One or more of the following DTCs (Diagnostic Trouble
Codes) may be present in the TCM (Transmission Control Module): P073400, P073500, P072900, P089600.
4.
Neutral condition in all gears except 5th & Reverse, usually with TCM P273300 set. DTCs for gear ratio(s) may also be set such as TCM
P073000, P073100, P073200, or P073400.
5.
Customer complaints of engine RPM flare at upshift or power-on downshift (kickdown) due to a worn modulator valve bore.
Note:
Transmissions starting with serial number 06J and later already have the latest valve body which is designed to prevent these symptoms.
