Replace the Lock-up ControlSolenoid Valve Assembly andRecheck:1. Replace the lock-up controlsolenoid valve A/B assembly(see page 14-'135).2. Turn the ignition switch OFFand reset the PCM by remov-ing the BACK uP (7.5 A) fusein the under-hood fuse/relaybox for more than 10 seconds.3. lJsing the scan tool, check tobe sure that the engine coolanttemperature is 176"F 180'C) orabove,4. Drive the vehicle at 55 mph(88 km/h) constantly for moretnan one mrnute.5. Recheck for code P0740 (40).
Does the OBD ll scan tool indicatecode PO74O or doesthe El indicator light indicate code 40?The svstem is OK ai this time.
Replace the Linear Sol€noidA$embly and Recheck:'1. Beplace the linear solenoidassembly {see page 14-138).2. Turn the ignition switch OFFand reset the PCM memory byremoving the BACK UP (7.5 A)fuse in the underhood fuse/relay box for more than 10seconds.3. Using the scan tool, check tobe sure that the engine coolanttemperature is 176"F (80'C) orabove.4. Drive the vehicle at 55 mph (88

NOTE: Codo P0715 (15) on the PCM doesn't always moan there's an electricalproblem in the mainshaft or countershaft speed sensor circuit; code P07'15 (15)may also indicate a mechanical problem in the transmission. Any problem caus-ing irregular countershaft to mainshaft spoed difference can cause this codo; thiscan sometimes be seen in A'/T Free2e Data. Freeze Data can also indicate an elec-trical problem in the sensor circuits ;f one of the sensors reads 0 mph during atest dnve.
