Test lst, 2nd, 3rd and 4th Clutch
Pressure:Measure the 1st, 2nd, 3rd and 4th
clutch pressure (see page 14119
thru 14-121).
Ropair the hydrlulic systom !snecessary {see page 14-1 19 and11-1211.

the service limit?
Replace Shift Control Solenoidvalve Assembly, Linear SolenoidAssambly and Rechock:1. Replace the shift controlsolenoid valve A'/B assembly(see page 14-106).2. Replace the linear solenoidassembly lsee page 14 108).3. Turn the ignition switch OFFand reset the PCM memory byremoving the EACK UP (7.5 A)tuse in the under hood fuse/relay box for more than l0
seconds,4. Drive the vehicle at over 12mph (20 km/h) in 1st, 2nd,3rd
and 4th gear for more than 30seconds at P1 position.
5. Recheck tor code P0730 (41).
Does the OBD ll scan tool orthe Ed indicator tight indi
