Auto Transmission Problem

[Bullitt2001]

I would appreciate any help. My 99 P-11 with 122k had a check engine light come on. It started to shift hard sometimes and feels like something is holding it back on power.It is an automatic and a 732 code showed up on scope.Any ideas?

I don't know if you have seen the FSM for this...



**This is an OBD-II self-diagnostic item and not available in TCM
self-diagnosis.
**This malfunction will not be detected while the O/D OFF indicator
lamp is indicating another self-diagnosis malfunction.
**This malfunction is detected when the A/T does not shift into
second gear position as instructed by the TCM. This is not
caused by electrical malfunction (circuits open or shorted) but
by mechanical malfunction such as control valve sticking,
improper solenoid valve operation, etc.

Malfunction is detected when ... A/T cannot be shifted to the 2nd gear position even if electrical circuit is good.

Check items (Possible cause)
**Shift solenoid valve B
**Each clutch
**Hydraulic control circuit

Gear position supposed by TCM................................ ..............2
In case of gear position with no malfunctions....................... .....2
In case of gear position with shift solenoid valve B stuck open.....3
