2006 ram 1500 slt 4x4 5.7 hemi
.Im getting codes p0841 and p0700???
I went to leave for work this morning and went to take off and it feels like the truck is in a higher gear like 3rd maybe and its really sluggish and revs high to barely take off and i dont think it shifts after i get moving..any ideas?? It has always worked perfectly till this morning.

 

By the way yesterday i was told to put some dielectric grease on my tipm post..i did this and didnt drive it after until this morning and now i have this problem?? Im gonna take it all off and see if it fixes it before i start spending.money..could it possibly be low tranny fluid? I havent checked yet.

 

Wilson,

Here are the descriptions of the error codes your posted.

P0700-TRANSMISSION CONTROL SYSTEM (MIL REQUEST)

• When Monitored: Ignition on and battery voltage greater than 10 volts.
• Set Condition: An active DTC is stored in the TCM. One Trip Fault. Three good trips to turn off the MIL.

Possible Causes

DTC PRESENT IN THE TRANSMISSION CONTROL MODULE

P0841-LR PRESSURE SWITCH RATIONALITY


Theory of Operation

The Transmission system uses five pressure switches to monitor the fluid pressure in the LR, 2C, 4C, UD, and OD clutch circuits. The pressure switches are continuously monitored for the correct states in each gear as shown.

• When Monitored: Continuously with the ignition on and engine running.
• Set Condition: The DTC will set if the LR Pressure Switch reads open or closed at the wrong time in a given gear.

Possible Causes

LOSS OF PRIME AND/OR TIPM DTC PRESENT
LOW FLUID LEVEL
LOW LINE PRESSURE
REVERSE CARRIER SNAP RING DISLODGED
CRACKED OR MISINSTALLED PRIMARY OIL FILTER OR FILTER SEAL
STICKING MAIN REGULATOR VALVE IN PUMP VALVE BODY
NO. 1 CHECK BALL CUT OR DAMAGED
WIRING AND CONNECTORS
(T50) LR PRESSURE SWITCH SENSE CIRCUIT OPEN
(T50) LR PRESSURE SWITCH SENSE CIRCUIT SHORTED TO GROUND
(T50) LR PRESSURE SWITCH SENSE CIRCUIT SHORTED TO VOLTAGE
TRANSMISSION SOLENOID/TRS ASSEMBLY
POWERTRAIN CONTROL MODULE (PCM)

 

Sorry i tyoed it wrong..its p0700 nd p0876..i was thinking its the governor pressure solenoid in the tranny??

 

P0876-UD PRESSURE SWITCH RATIONALITY


Theory of Operation

The Transmission system uses five pressure switches to monitor the fluid pressure in the L/R, 2C, 4C, UD, and OD clutch circuits. The pressure switches are continuously monitored for the correct states in each gear as shown.

• When Monitored: Continuously with the ignition on and engine running.
• Set Condition: This DTC is set if the UD pressure switch is in the wrong state for the current gear. For example, this code would be set if the UD pressure switch remained off while the transmission was in second gear.

Possible Causes

RELATED TCM POWER INPUT DTCS PRESENT
LOW FLUID LEVEL
NO. 2 CHECK BALL CUT OR DAMAGED
LOW LINE PRESSURE
CRACKED OR MIS-INSTALLED SUMP FILTER OR SEAL
LOOSE COOLER RETURN SPIN ON FILTER (IF EQUIPPED)
STICKING MAIN REGULATOR VALVE IN PUMP VALVE BODY
(T29) UD PRESSURE SWITCH SENSE CIRCUIT OPEN
(T29) UD PRESSURE SWITCH CIRCUIT SHORTED TO GROUND
(T29) UD PRESSURE SWITCH SENSE CIRCUIT SHORTED TO ANOTHER CIRCUITS
TRANSMISSION SOLENOID/TRS ASSEMBLY
POWERTRAIN CONTROL MODULE (PCM)

 

From what ive read its the solenoid..u think so?

 

Unfortunately, I cannot provide diagnosis via the forum. Perhaps someone else will chime in here soon.

 

I have also noticed it isnt in limp mode in the evenings when i leave work when its warmer outside..in the morning when its cold it goes back into limp mode...my buddy said my governor pressure solenoid is freezing up on me..said its a normal problem with these trannys
