Fix code P0750 P0755 P0760 P0765 Chrysler Minivans

P0700, P0750 and P0755 codes I was driving at 65 mph and the 2003 Dodge Caravan down shifter to low gear and the - Dodge 2003 Caravan question. The following TSBs of Hyundai are related to DTC P0755. 1996 Hyundai Accent Axle Assembly TSB Details 1996 Hyundai Elantra Axle Assembly TSB Details 1997 Hyundai Accent Axle Assembly TSB Details 1997 Hyundai Elantra Axle Assembly TSB Details 1997 Hyundai Tiburon Axle Assembly TSB Details.

The solenoid pack in these Chrysler vehicles regulates transmission oil pressure to activate the clutch packs and make the vehicle shift. The solenoid receives a pulsed signal from the PCM and the solenoid responds by opening and closing the port up to 10 times per second. This action is called “duty cycling.” So if the solenoid is open 5 times in one second, it’s at 50% duty cycle.

The PCM constantly checks the condition of the solenoid pack and reports any of the P0750, P0755, P0760, P0765 trouble codes when it finds a problem. Then it puts the vehicle into “limp in” mode so you can drive the vehicle into the shop. To confirm that the problem is actually the solenoid pack all you need is a digital multi-meter. Disconnect the electrical connector from the solenoid pack and test the resistance between pins 1 & 5, 1 & 7, and 1 & 8. The yellow/red wire goes to pin 1. All the solenoids should read 1-3 ohms. If the readings are out of range, replace the solenoid pack.

If you need a new solenoid pack, check out this link. Just enter your vehicle info at the top to double check the part number.

Hey guys, I've had this problem for awhile now and I'm hoping to finally solve it. Thanks to all who have helped me so far. Here is the summary of what happens.
Every few weeks, I get a CEL and flashing arrow. After driving around in 3rd gear for a few miles or so, the car finally reverts back to driving normally. I reset the CEL light and the car is fine for a few weeks. Then, it all happens again. The code I pull is P0755, Shift Solenoid B Malfunction. I have a few questions about this.

P0755 Ford

a) Am I doing any more damage by letting this cycle continue?
b) How probable is it that replacing the shift solenoid would solve this?
c) How much should I expect it to run me to have the shift solenoid replaced
d) If I have one replaced, should I have all of them replaced?

P0755 Jeep

P0755 Rav4

Thanks so much guys.
