This is the OD Solenoid. There is a TSB out that covers the 2000-2001 Ram truck.
EFFECTIVE DATE: Oct. 02, 2000
SUBJECT:
46RE Transmission MIL Due To DTC P1740 – TCC or OD Solenoid Performance
OVERVIEW:
This bulletin involves the replacement of the transmission pressure boost valve cover
plate.
MODELS:
2000 - 2001 (AB) Ram Van
2000 - 2001 (AN) Dakota
2000 - 2001 (BR/BE) Ram Truck
2000 - 2001 (DN) Durango
NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 46RE
TRANSMISSION BUILT BEFORE AUGUST 01, 2000 (MDH 0801XX).
SYMPTOM/CONDITION:
The customer may complain of a Malfunction Indicator Lamp (MIL) illumination. Upon
further analysis, it is determined that the MIL is caused by Diagnostic Trouble Code (DTC)
P1740 - Torque Converter Clutch (TCC) or Overdrive Solenoid Performance. Other than
the MIL, the customer may not notice any other condition with the transmission.
This condition may be caused by an intermittent and momentary TCC disengagement
condition. The transmission valve body pressure boost valve cover plate has been revised
with a larger size orifice hole to address this condition.
DIAGNOSIS:
1. Warm the transmission to normal operating temperatures.
2. Using the DRB IIIò, perform a torque converter clutch (TCC) stall test. The stall test
has been revised so that the TCC remains engaged for a period of four (4) seconds.
NOTE: THE DRB III MUST BE OPERATING AT RELEASE LEVEL 50.4 MDS2
SYSTEM CIS CD2067 OR HIGHER (AVAILABLE THE WEEK OF OCTOBER 2,
2000) IN ORDER TO PERFORM THE REVISED TORQUE CONVERTER
CLUTCH STALL TEST. DO NOT USE EARLIER VERSION STALL TEST TO
DETERMINE CONDITION OF THE TORQUE CONVERTER CLUTCH.
3. If the engine stalls as a result of the TCC stall test, then perform the Repair
Procedure.
4. If the engine does not stall, as a result of the TCC stall test, then further diagnosis is
required. The technician may want to consider the following components during
their additional diagnosis: a cut or worn input shaft seals, a missing pump lock-up
circuit check ball, or worn converter hub, input shaft, reaction shaft, and pump rotor.

PARTS REQUIRED:
1 04617015 Plate, Pressure Boost Valve Cover (46RE)
1 02464324AB Gasket, Trans Pan
10(AR) 05010124AA ATF+3, Transmission Oil Type 7176 (2000 M.Y.)
10(AR) 05013457AA ATF+4, Transmission Oil Type 9602 (2001 M.Y.)
REPAIR PROCEDURE:
1. Clean the pressure boost valve cover plate to remove any dirt or rust inhibitor prior to
installation. The revised cover plate will have a 1.75 mm (0.069 inch) orifice hole
versus a 1.22mm (0.048 inch) orifice hole in the original plate. Make sure it is clean.
2. Using the appropriate Service Manual, Group 21 – Transmissions and Transfer Case,
replace the transmission pressure boost valve cover plate p/n 04617012.
3. Verify fluid level after warming up the transmission and cycling the shift lever several
times.
4. Verify, and if required, adjust the transmission shift linkage and the transmission
throttle valve cable per the appropriate Service Manual procedures.

SOURCE: 2001 dodge ram 1500 fault code 1687
Heryou go its a pretty lengthy diagnostic procedure it appears there is a power problem with the instrument cluster here is the code meaning hope it helps have a good dayDB
SOURCE: i have 2 engine codes for a 2001 dodge ram 1500
I have never seen P0000 but P1740 is a standard autotrans code it should have another code with it,P1740 just tells you that the fault is in the automatic transmission.
SOURCE: Truck (2001 Dodge Ram 1500) runs fine. Check
I found that the code is set for:
P1740....TCC Solenoid or Overdrive Solenoid performance
which indicates that a rather inexpensive fix is in order, not a complete transmission replacement!! The TCC is the solenoid which controls the locking of the transmission converter so that you get better gas mileage with no "slippage" while at highway speeds, which is normal when the converter is unlocked as you slow down. If it is locked and the solenoid fails to release it the car will stall when you come to a stop since the fluid in the converter fails to act as a clutch and the engine is connected directly to the transmission input shaft. If it never locks then the oil in the transmission will overheat at highway speeds since ther "slippage" will always be present in the converter cauasing frictional heating of the oil.
Whenever you get a quote from a shop ALWAYS get at least two more!!! No matter what the job is, even a muffler replacement get many quotes. Go to a reliable transmission repair shop and ask for their opinion. In my humble opinion the shop that told you that you need a new transmission is just hungry for work - stay away!!!!

SOURCE: what dose the code p1740 mean ? I have a 2001
its a trans code that is manufacture controlled meaning the information for the code meaning is not required by law for them to describe. so my code lookup program does not have that info. but go to the dealer and if you can nice talk one of the techs and mabee he/she will look it up on the mds for you.
