Updated plug-in solenoid block for the Chrysler A604/41TE 4-speed; fixes erratic shifts, TCC shudder and the leaky stacked-gasket design on Caravan, PT Cruiser, Sebring and more.
A minivan, PT Cruiser or Sebring with the A604 (41TE) that suddenly holds second gear, flashes a P0750 low/reverse solenoid code, or shudders because the converter clutch will not apply properly is often due for a new solenoid block. This pack replaces OE 5140429AA along with 5015646AC, 5015646AB, 4504570AB and 698-100, and it comes with the pack-to-case gasket. It is the updated style that does away with the leak-prone stacked gasket used on early packs, so it also fits as an upgrade on older vans.
The 41TE was one of the first fully electronic, adaptive transaxles, and it has no bands or shift governor. Four solenoids in this pack, low/reverse, 2-4, overdrive and underdrive, are switched by the controller to apply and release the clutches, and built-in pressure switches confirm each apply. Transmission Digest explains that the controller constantly checks each solenoid circuit by switching it off and looking for the inductive voltage spike; when that check fails it stores a code and drops to second gear. On the 41TE the pack is external, bolted to the outside of the transaxle case, so it can be changed without removing the valve body.
P0750 is purely an electrical code. Transmission Digest lists the usual causes as the solenoid, the wiring and connectors between the pack and the controller, or the controller itself, and it describes a case where a weak common voltage supply set the code on every solenoid at once. Check the connector at the pack before anything else: the 40/41TE harness plug is known for spread and corroded pins that force second-gear failsafe. If you are chasing a leak, follow the trail upward first, because cooler lines, the fill tube, pressure taps, the vent and the input speed sensor all sit above the pack. Codes for converter clutch or switch valve faults often trace to a worn solenoid switch valve bore; our 41TE/A604 Ultradrive guide covers that repair, and the 41TE slipping-under-load guide covers pressure regulator wear that can look like a solenoid problem.
The listing covers the 41TE/40TE family and the closely related 42LE, including Dodge Caravan and Grand Caravan, Chrysler Town and Country and Grand Voyager, Chrysler PT Cruiser 2.4L (2001-2011), Sebring (1995-2010), Cirrus, Chrysler 200 2.4L (2011-2013), Dodge Avenger and Journey, and the 3.5L LHS, 300M and Prowler. Chrysler fitted several transaxles across these platforms, including the 62TE in later vans, so confirm you have a 41TE or 42LE and match the connector and bolt pattern on your old pack. Send us your year and VIN if you want us to check. More parts for this unit are on the 41TE collection page.
Disconnect the battery and, on most vehicles, move the air cleaner housing for access. Clean around the pack before removing it so dirt cannot fall into the open case ports, unplug the pack and input speed sensor connectors, then remove the mounting bolts. Scrape the case face clean, keep old gasket material out of the ports, fit the new gasket and pack, and torque the bolts to factory specification. Top up with ATF+4, clear codes and run the Quick Learn with a scan tool. If the fluid is dark, service it with an A604/41TE filter kit; if the clutches are already slipping, an A604/41TE master rebuild kit is the right fix.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Outside. On the A604/41TE the solenoid and pressure switch pack bolts to the outside of the transaxle case, so you do not need to remove the pan or valve body to replace it.
Only if the pack is the cause. P0750 is an electrical code that can also come from the wiring, the connector at the pack or the controller. Inspect the connector pins and check the circuit before replacing parts.
This updated pack drops the stacked gasket used on early packs, which was a real leak point. Still trace the leak upward first, since cooler lines, the fill tube, pressure taps, the vent and the input speed sensor sit above the pack and often drip onto it.
Use ATF+4. After installing the pack, clear codes and run the Quick Learn with a scan tool so the controller relearns clutch apply timing.
This pack is listed for the 41TE, 40TE and 42LE family. Later vans with the six-speed 62TE need to be checked against the old part, so send us your year and VIN before ordering.
