Ford Crown Victoria · 1998–2011
The 4R70W, 4R75W and 4R75E automatic transmissions used in the 1998-2011 Ford Crown Victoria are prone to shift solenoid pack failure, causing erratic shifting, failure to shift into certain gears, or the transmission getting stuck in a single gear (limp mode). The valve body carries several electronically controlled solenoids (Shift Solenoids 1 and 2, the TCC solenoid, and the EPC solenoid) that regulate hydraulic fluid flow to engage gear clutch packs. These solenoids wear out from heat cycling, fluid contamination, and electrical degradation over time. The Transmission Repair Cost Guide documents this as a common issue across Ford 4.6L-equipped vehicles. Codes P0750 and P0755 (shift solenoid A/B malfunction) and P0740/P0743 (TCC solenoid) are the most commonly associated DTCs.
Common Symptoms
- Harsh or delayed shifts between gears
- Transmission stuck in one gear (limp mode / failsafe)
- Erratic or unpredictable shift points
- Check engine light illuminated
- Transmission slipping between 2nd and 3rd gear
- No overdrive engagement
- Flare shifts (RPM spike between gears)
- Transmission warning light on dashboard
How to Fix
Replace the shift solenoid assembly together with the TCC solenoid rather than one solenoid at a time. On the 4R70W/4R75W/4R75E, Shift Solenoids 1 and 2 share one assembly, while the TCC and EPC solenoids are separate parts on the valve body, and they typically fail within a short window of each other. Solenoid pack part cost is $80-150, labor is 2-3 hours ($200-450). Always replace transmission fluid and filter simultaneously. If the transmission has been driven extensively in limp mode, internal clutch damage may require a rebuild ($1,800-2,800), which is beyond the cost range shown for the solenoid job.

Dodge Intrepid · 1993–2004
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.

Mazda Tribute · 2001–2008
Same CD4E automatic transmission as the Ford Escape, prone to premature failure. Internal clutch and servo bore wear. V6 models with CD4E are most affected.
Common Symptoms
- Harsh 1-2 shift
- Slipping in 3rd and 4th gear
- Shudder on acceleration
- Delayed engagement
- Burning trans fluid smell
How to Fix
Rebuild or replace transmission with remanufactured unit. Use updated servo bore kit during rebuild. Fluid changes every 30k miles help but do not prevent failure.
Owner tips & cautions
- TipThe 4-cylinder model uses a different (more reliable) transmission — CD4E problems are V6 specific

Frequently asked questions
What does P0750 mean?
P0750 stands for "Shift Solenoid A Malfunction." This code indicates the transmission control system detected a malfunction in shift solenoid 'A', one of the electrically operated valves that direct hydraulic fluid to engage gears. The computer commands these solenoids to control upshifts and downshifts, and it monitors their circuits and the resulting gear changes. When solenoid A doesn't respond electrically as expected — or the resulting shift doesn't happen correctly — this code is set. You may notice harsh, delayed, or missing shifts, or the transmission may enter a fail-safe (limp) mode.
What are the most common causes of P0750?
The most common causes of P0750 are: Failed or stuck shift solenoid A, Open, shorted, or chafed solenoid wiring, Corroded or loose transmission connector, Low, dirty, or degraded transmission fluid, Clogged solenoid or valve body passages, Internal valve body or hydraulic fault, Faulty transmission control module (TCM). The specific cause varies by vehicle.
How much does it cost to fix P0750?
Repair costs for P0750 range from $100 to $4,500, depending on the vehicle and root cause.
