TEST ACTION APPLICABILITY
1Note: Ensure the SKIM has proper communication and that there are no
SKIM DTC's present before continuing.
At this point in the diagnostic test procedure, it is assumed that all of the engine
electrical systems are operating as designed and are not the cause of a start and stall,
or a no start problem.
The following additional items should be checked as possible mechanical problems.
Any one of these items can produce a start and stall, or no start condition; none can
be overlooked as a possible cause.
1. ENGINE VALVE TIMING - must be within specifications
2. ENGINE COMPRESSION - must be within specifications
3. ENGINE EXHAUST SYSTEM - must be free of any restrictions
4. ENGINE PCV SYSTEM - must flow freely
5. FUEL - must be free of contamination
6. ENGINE SECONDARY IGNITION CHECK - must exhibit a normal scope pattern
7. THROTTLE BODY - must be free of any coking conditions.
8. IDLE AIR CONTROL MOTOR - passages must be free of any debris or carbon.
Always look for any Technical Service Bulletins that may relate to this condition.All

When Monitored and Set Condition:
P-0740 TORQUE CONV CLUTCH, NO RPM DROP AT LOCKUP
When Monitored: Continuously when no matured or maturing Trouble Code and throttle
position >10% and constant for 4.4 seconds before TCC engagement requested: No TCC
solenoid circuit, any cam/crank-related code, VSS, any TPS-related code and Battery
voltage >11.0
Set Condition: Torque Converter malfunctions that are detected are the FTC not locking
up properly when desired, and the torque converter not unlocking properly when desired.
3 consecutive test failures over one trip will store the code. 2 bad trips will set the code.
