Really.
Ecomike is one of our resident experts, so I would listen to what he says.
You have 3 choices.
1: Do as he says. Get some tools, investigate, learn, fix it.
2: Drop it off at the dealer and pay them to fix it.
3: Sell the truck.
Judging by your last post I'd say go with #3....
Cherokees are finicky and sometimes problems arise that require you to actually get your hands dirty and use that organ between your ears. Sounds to me like you want someone to wave a magic wand and fix your truck for you.
Since you seem too lazy to do it, I googled it for you. Took 2.4 seconds:
P0740 CHRYSLER - Torque Converter Clutch Circuit
Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted
Help with this
When is the code detected?
Torque Converter Clutch (TCC) unlocked for 10 sec., ECM commands converter lock-up and did not record engine speed drop.
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock
- Vehicle may not shift into the highest gear
P0740 CHRYSLER Description
The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (
ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.
