Replace Shift Control Solenoidvslve Assembly and Recheck:1. Replace the shift controlsolenoid valve A/B assembly(see page'14 136).2. Turn the ignition switch OFFand reset the PCM memory byremoving the BACK UP (7.5 A)fuse in the under-hood fuse/relay box for more than 10seconds.3. Drive the vehicle at over 12mph (20 km/h) in 1st,2nd,3rd,and 4th qear for more than 30seconds in E position.
4. Recheck for code P0730 (41).
Does the OBD ll scan toolindicate code P0730 or doesthe E indicator light indicate code 41?
The svstem is OK at this time.
Replace Linea. Solenoid Ass€mblyand Recheck:1. Replace the linear solenoidassembly lsee page 14-138).2. Turn the ignition switch OFFand reset the PcM memory byremoving the BACK UP 17.5 A)fuse in the underhood fuse/relay box tor more than 10 sec'onos.3. Drive the vehicle at over '12
mph {20 km/h) in 1st,2nd,3rd,and 4th geal for more than 30seconds in -Da position.
4. Recheck for code P0730 (41).
Does the OBD llscan toolindicate code P0730 or doesthe Di indicator light indi-cate code 41?
The syslem is OK at this time.
