Hi I have a 1998 Ram 4X4. I have replaced the governor pressure solenoid and the automatic shift solenoid. New filter and fluid, check engine light still comes on as bad automatic shift solenoid but I replaced that part. I have cleared the code with the new solenoid in it as well but still no luck. Trans will not shift up and a good amount of lost power is the result. Any ideas on how to fix or have the truck accept the new solenoids??? I'm at a lost and the snow is here so I need the truck, please help if you can. Thank you.

 

Automatic shift solenoid?

What code are you getting?

 

Code is P0753 and I replaced this

 

 

P0753 Trans 3-4 Shift Sol/Trans Relay Circs

If you replaced the TCC and O/D solenoids, and are still getting codes..... are you getting power TO the solenoids? (red wire on 8 pin connector.)

Also check the connectors at the PCM, they sometimes get dirty/corroded, and don't make good contact. All of that puts the trans in limp mode, and you basically only have one gear.

 

Thinking about selling the truck....in-laws just passed down a 2002 jeep grand Cherokee...think anyone will buy with the issues it has and what's a fare price? $1500???

 

Fix it first, get more money out of it.
