Hi,
I have a 99 caravan 3.3L. The "service engine soon" light went on and I notice that the transmission is not shifting. It is in 3000 RPM at 60kph.
I tried to turn the engine on, off, on, off and on again to check the trouble code, but I could not see any flashing lights, and could not find CEL.
Please help.
Thanks

 

The transmission is most likely in what Chrysler calls "limp mode". A fault has been detected so the transmission is kept from shifting past second gear. The SES light is telling you the Powertrain Control Module (PCM) has detected a fault and is storing a code. Two ways to read the code. The best way way is to read them with a scanner -done free at most parts stores at least in the US. The key cycle method will give you less comprehensive codes. You count the flashes of the SES light. That is your check engine light.

 

Hi Cougar,
Thanks for replying. The code is 755, which is the 2/4 solenoid switch. Can this be replaced DIY? Do I need a mechanic to do this?

Thanks

 

Hi I'm having the same problem SES light is on. seems to be shfting to high gear. 1999 ply voyager. air bag light aiso on. I'v seen there was a recall 4 this at one time. how can I find out if the recall was done or not ?

If you send me a pm with the last 9 of the vin and mileage, I can tell you. As far as the transmission problem. I would need to know the codes.

 

Symptom:
P0755-2-4 SOLENOID CIRCUIT
When Monitored and Set Condition:
P0755-2-4 SOLENOID CIRCUIT
When Monitored: Ignition key is turned from the OFF to RUN position and/or key is
turned from the CRANK to the RUN position, then every 10 secs thereafter, or when a
speed ratio or pressure switch error occurs. All 4 solenoids are tested for continuity
continuously.
Set Condition: If a solenoid is On, power is momentarily interrupted, then reenergized. If
solenoid is Off, power is momentarily energized, then deenergized. If an inductive spike is
not sensed by the TCM, it is retested. If the solenoid fails 4 times the code sets.

where can I find the 2-4 solenoid circuit?

 

The 2/4 solenoid is part of the solenoid pack mounted on the front of the transmission. An electrical connector and wire harness connects it to the transmission control module mounted on the passenger side fender wall aft of the windshield washer bottle.
