46RE Tcc Solenoid 1999, new and ready to install. Fits the 46RE. Ships fast from the USA.
If your 1999 Ram, Durango or Dakota with the 46RE cruises at high rpm because the converter never locks, refuses the 3-4 upshift, or throws P1740 or a TCC code, this is the replacement lockup solenoid assembly for that late-1990s design. It carries both the torque converter clutch solenoid and the overdrive solenoid on one bracket with the internal wiring harness and the round case connector, which is how Chrysler built it. It is listed for all 1996-99 A500 and A518 units, so it also covers 42RE and 47RE trucks from those years.
By 1999 the 46RE had a few years of electronic governor behind it. The governor solenoid handles first through third; this two-solenoid assembly handles the rest. The overdrive solenoid exists only for the 3-4 shift. The lockup solenoid, when the PCM grounds it, strokes the switch valve so converter feed reverses and the converter clutch applies. Power for both comes from the transmission control relay through pin 1 of the case connector. On the gas-engine PCM the overdrive control is pin B21 and lockup control is pin B11, each reading close to 0 volts while the solenoid is commanded on, which makes back-probing on a road test a reliable check.
Run the engine during electrical tests; the relay is not powered key-on-engine-off on these units. Back-probe B21 and B11 while driving: if the voltage never drops, the PCM is not commanding the shift or lockup, and the solenoid is not your problem. Measure the windings at the case connector and compare them to each other. Sonnax also points out that a restricted cooler or drainback fitting causes lockup slip and 1740 complaints, so bypass the cooler before buying. Our 46RE solenoid testing guide lays out the order, and if fourth engages but slips, read the 46RE 3-4 clutch failure guide because that is a mechanical problem.
This assembly is listed for 1996-99 A500 and A518 transmissions. There is one trap worth knowing: two lockup solenoids were used across these applications, identified by connector color, a low-resistance white style and a higher-resistance blue style, and they run different control strategies. Putting the wrong one in causes surge, lockup shudder and TCC slip codes. Compare the connector color and part number on the assembly you remove with this one, or send us your year and VIN and we will confirm it. ATSG also notes that 1996-early 2000 governor sensors are a different design from late-2000-up parts and the two do not mix, so 2000 and later trucks need the 2000 46RE TCC solenoid instead. See every part for this unit on the 46RE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is the combined overdrive and lockup solenoid assembly with the internal wiring harness and the round case connector, the way the 46RE uses it.
It is listed for 1996-99. Late 2000-and-later trucks use a different design, so use the 2000 version for those. Some early 2000 trucks carried the earlier parts; compare your connectors or send us your VIN.
The most common reason is the wrong solenoid type. White and blue connector lockup solenoids have different resistance and control strategies and do not interchange. Match the one you removed.
Only if the overdrive solenoid or its circuit is at fault. Confirm the PCM is commanding fourth and check the overdrive clutch before replacing it.
ATF+4 only. Set the level hot with the engine idling in Park.
