U are going to need to overhaul the transmission here, the smoke is the trans overheating from excessive slippage i suspect.code for wrong gear ratio's mean the input and output shaft speed are out of symc for the gear the trans is in, the 3rd or 4th gear is the usual codes, this sometimes is caused by defective speed sensors but most times the trans is slipping and the TCM detects that and sets a code

  • A/T or M/T (auto or stick, gee)
  • if A/T is this the 42RE box>? are you in DRIVE? or 1 or 2 gear.
  • does rpm rise above 3000 rpm > at your attempt? if not ,its a bad engine (weak)
  • is the shift linkage even shifting correctly (movement top and bottom)
  • check levels yet. (and for pink ./red AFT not black-metal flake
  • change the filter yet? or skip service. at 50k miles. ?????
  • check all fuses yet>?
  • using a basic OBD2 scan tool are there any tranny DTC errors?>
  • does the FSM stall test pass? in 1st.? and reverse?
  • if stall fails, slips , then tranny bad. if not its really stuck in 1st gear.
The TCM commads the gear change, there is no valve body brain.
the TCM shifts to second with good inputs to the TCM
if the TCM sees bad inputs it will tell you, SCAN IT.

Let me give more history on the question, replaced 98 Cherokee auto transmission with 2000 tranny. DTC code P0753. DBR says short to ground, no communication from TCM to PCM. Electrical problem occurs...


code p0753 refers to shift solenoid (SS) A electrical===causes--wiring---shift solenoid---ECM/TCM
I'm thinking that with the transmission upgrade and the fault code showing wiring and TCM as faulty I would be paying serious attention to the configuration of the wires in the plugs. Just because the connectors go together may not mean that the corresponding wires go to the right bits. you may have to invest in a good work shop manual for the gear boxes and trace the wiring circuits out and adjust the pins in the connectors to the right circuits.

Engine light on with code P0725


P0725 JEEP Description The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).
The code is set when the TCM does not get an engine speed signal from the ECM.
Could be a problem with either computer, the link between the two, or the crank sensor.

1998 jeep grand cherokee 4x4. have the p0740 code. have to start from neutral, then shifts faily well. May start fluttering and making noise, have to put back to N, then to D and once again will shift. ...


P0740 JEEP - Torque Converter Clutch Circuit
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock
- Vehicle may not shift into the highest gear

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

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.

P0740 JEEP 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.

Error P0700. What is the cause? How to repair it?


P0700 JEEP - Transaxle Control System Malfunction
The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transaxle controls.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Driveability problems
- Transaxle shifting problems

Possible causes
- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module

Tech notes: Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem. So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

Good luck (remember to rate this answer)

1994 JEEP GRAND CHEROKEE-TRANSMISSION "SLIPS" ON TAKE OFF.


First of all make sure you are checking the fluid right. Some people do not know that in order to check transmission fluid the engine needs to be running and the temperature needs to be sort of warm althought you should be able to get a good Idea just by the engine running. In this instance you might have a governer valve that isn't properly working to shift the engine when hydraulic pressure reaches a certain PSI. I would suggest having it flushed and put in new fluid and filter. If this doesn't work the problem is more serious and might need some professional assistance.
