P0750 on Dodge by model: symptoms, diagnosis and fix
The 42LE (A606) 4-speed automatic transmission used in the Intrepid from 1993 to 2004 is prone to premature failure, including solenoid pack issues, torque converter lockup failure, and internal clutch pack wear. The transmission often develops harsh shifting, slipping, and eventually limp mode. The solenoid pack is the most common failure point and is accessible through the oil pan without removing the transmission. Later 42LE units are somewhat improved but still problematic.
Common Symptoms
- Harsh or delayed shifting
- Transmission slipping under acceleration
- Stuck in 2nd gear limp mode
- Check engine light with transmission codes
- Shudder during torque converter lockup
How to Fix
Scan the TCM/PCM for transmission-specific codes (common ones point to the solenoid pack, input/output speed sensors, or torque converter clutch performance), then verify fluid condition and line pressure before condemning the unit. If the transmission has harsh shifts, limp mode, or lockup shudder with no major metal debris in the pan, replace the solenoid pack/filter, service the transmission with the correct ATF+4 fluid, and inspect the valve body and wiring; this repair typically runs about $400-$900. If slipping persists, the fluid is burnt, or clutch material/metal is found in the pan, the transmission usually needs a full rebuild or quality remanufactured replacement with updated internal components and torque converter, typically costing $2,000-$3,500 installed.

The 41TE automatic transaxle in the Stratus (and the related 40TE used on some 2003-2006 models) suffers from solenoid pack failures that cause harsh shifting, delayed engagement, and limp mode. The solenoid pack contains the shift solenoids, torque converter clutch solenoid, and pressure control solenoid. Electrical connector corrosion is a common contributing factor. The solenoid pack bolts to the outside of the transaxle case and can be replaced without removing the transmission, making it a relatively affordable repair compared to a full transmission rebuild.
Common Symptoms
- Harsh or erratic shifting between gears
- Delayed engagement when shifting to Drive or Reverse
- Transmission stuck in limp mode (2nd gear)
- Check engine light with P0700 series codes
- Intermittent shifting issues that worsen when cold
How to Fix
Read the stored transmission codes first, then check fluid level and condition, the transmission control relay feed, TCM power and grounds, and the solenoid pack connector for corrosion, since a wiring or power fault can force limp mode with a good pack. If a solenoid circuit or pressure-switch code points to the pack, replace the solenoid/pressure switch assembly as a unit (it is held to the transaxle case by three bolts), then perform the TCM Quick Learn procedure with a scan tool. Internal clutch damage from prolonged driving in limp mode can push the bill toward a rebuild.

The 42RLE 4-speed automatic in V6 Chargers suffers from solenoid failures and corrosion in the 10-pin solenoid harness connector. It causes slipping, harsh shifts, limp mode, and P0750/P0755/P0760/P0765 codes. On some 2006 Chargers with the 42RLE, the cup plug that retains the park pawl anchor shaft may be improperly installed, which can keep the transmission from reaching Park (DaimlerChrysler recall 05V460).
Common Symptoms
- Slipping gears
- Harsh shifts
- Transmission stuck in limp mode
- P0750/P0755/P0760/P0765 codes
- Speed limited to 40 mph in limp mode
How to Fix
Install the new-design 42RLE 10-pin connector (a dealer wiring repair) and replace the solenoid pack. Verify the park pawl recall has been completed. Use ONLY Mopar ATF+4 (68218058AC).

The 3-speed A413 (TorqueFlite) automatic used with the four-cylinder engines and the 4-speed A604 (Ultradrive) automatic offered with the 3.0L V6 (1992-1994) are both prone to failure, but the A604 is significantly worse. The A604 was Chrysler's first electronically controlled automatic transmission and suffered from numerous reliability issues including solenoid failures, premature clutch pack wear, and TCM (Transmission Control Module) problems. The A413 is more robust but still develops torque converter and front pump issues at higher mileage. The A604 earned a terrible reputation, mostly from its 1989 and early-1990 builds.
Common Symptoms
- Harsh or banging shifts
- Transmission slipping under acceleration
- No 2nd or 3rd gear (solenoid failure)
- Limp mode with only one gear available
- Delayed engagement from Park to Drive
How to Fix
First check the fluid level and type: the A604 must run Mopar ATF+3 (now ATF+4), and Dexron fill is a common cause of failure. If an A604 car is stuck in second gear, it is in limp-home mode; have the transmission computer's fault codes read before you condemn the unit, because limp mode is often misdiagnosed and leads to unnecessary replacement. On the A413, shudder under light to moderate acceleration can come from a leaking front pump, which can be repaired without a full rebuild. Heavy slipping or a burnt clutch pack needs a rebuild or a reman unit.
