47RE Tcc Solenoid 2000, new and ready to install. Fits the 47RE. Ships fast from the USA.
If your 2000-2003 Ram 2500 or 3500 with the 47RE has quit locking the converter, hangs in third, or keeps setting P1740, this is the factory-style fix for the electrical side. It is a new Mopar-numbered overdrive and lock-up solenoid assembly with harness, 52118500AB, interchanging with 12420C, TCS51 and 22954C. It is built for A500 and A518/A618 transmissions from 2000 on with the round 8-pin case plug, which includes the 47RE behind the 5.9L Cummins and 8.0L V10.
Apart from governor pressure, the PCM in a 47RE truck directly controls two events: the 3-4 shift and torque converter lockup. This bracket holds both coils. Grounding the lockup coil lets converter oil reverse and clamp the converter clutch, which is what keeps a loaded Cummins from turning extra rpm and heating the fluid on the highway. The overdrive coil does nothing but command fourth. For 2000 Chrysler moved to a square plastic governor pressure sensor, and the harness had to change with it; Sonnax uses that sensor change as one of the ways to tell an early valve body from a late one. Sonnax also notes the TCC solenoid feed circuit is one of the real differences between the 47RE and the later 48RE, so do not assume parts interchange across that line without checking.
Check resistance first: ATSG lists 25 to 40 ohms for each coil, measured through the case connector. If both read correctly, do not buy parts yet. Transmission Digest documented P1740 on 2000-01 Ram pickups, Ram Vans, Dakotas and Durangos with the 46RE or 47RE caused by a reducing-pressure exhaust orifice in the boost valve cover plate that is too small, which slows the pressure build lockup needs. The fix is drilling that orifice to 0.069 inch or installing revised plate 04617012. Transmission Digest's 740/1740 article also lists non-converter causes of TCC slip codes worth ruling out. Our Ram 2500 Cummins shift problems guide and Ram 3500 version walk through the road test and code checks.
Listed for all A500 and A518 transmissions from 2000 on with the round 8-pin connector, which covers the 47RE in 2000-2003 Ram 2500 and 3500 trucks. The harness is made to plug into the late square plastic governor pressure sensor. If your valve body still has the round gold metal transducer, as an early or swapped unit might, order the 1996-1999 47RE TCC solenoid instead. Compare your old part to the photo or send us your year and VIN if there is any doubt. Matching parts are in the 47RE parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is listed for all A500 and A518 transmissions from 2000 on with the round 8-pin case plug, which includes 2000-2003 47RE trucks with the square plastic governor pressure sensor.
Not as a plug-in. 1996-1999 units use the round metal governor transducer, which this harness does not connect to. Order the 1996-1999 version.
The listing is the Mopar overdrive and lock-up solenoid assembly and harness, number 52118500AB, interchange 12420C, TCS51 and 22954C.
No, only the overdrive and TCC solenoid assembly with harness. The 2000-up master solenoid kit adds the governor solenoid, sensor, filter and gaskets.
ATF+4. Check the level hot in neutral after the road test. No programming or relearn is needed.
