P0758 on Chrysler by model: symptoms, diagnosis and fix
The rear-mounted 42LE (A606) automatic can drop into limp-in (fail-safe) mode when the electronic shift solenoid pack develops internal faults. Symptoms are the transmission locking into a single gear (commonly 2nd, or only 1st and reverse) until the ignition is cycled, often accompanied by a check-engine/transmission light. This is distinct from the fluid-overheating and AutoStick harsh-shift issues: here the solenoid pack itself (or its wiring/connector) is the root cause and typically sets solenoid-performance codes.
Common Symptoms
- Transmission stuck in one gear (limp mode)
- Only 1st and reverse available after warm-up
- Harsh or no upshift with warning light
- Fault clears after ignition off/on
- No torque-converter lockup
How to Fix
Scan for codes and confirm with pressure/solenoid tests before parts replacement. Replace the shift solenoid pack (reman Mopar A606/42LE solenoid pack, PN 4539766) along with a fresh filter and correct ATF; cycling the ignition off/on temporarily clears limp mode as a get-home measure. Verify the transmission connector and internal wiring harness are not the fault before condemning the pack.
What you need to diagnose it
The repair instructions explicitly call for reading stored codes. Use a scanner that can read the named code families before choosing a repair.The recommended scanner supports these code families; confirm your exact year, model and module coverage before buying.

Reading and clearing the code is DIY work. Module replacement or reprogramming is not — most modules are VIN-programmed, so a new one does nothing until a shop codes it to your car. Check for an open recall or service bulletin before buying anything.

Frequently asked questions
What does P0758 mean on a Chrysler?
P0758 stands for "Shift Solenoid "B" Electrical." This powertrain code indicates an electrical fault in the transmission's shift solenoid 'B' circuit. Shift solenoids are electrically controlled valves that route transmission fluid to engage the correct gears (solenoid B is commonly associated with the 2-3 shift). The transmission computer detected the solenoid circuit electrical value (voltage/current) outside the expected range. This can cause harsh or missed shifts, slipping, or the transmission entering limp mode, and should be addressed to avoid further transmission damage. On Chrysler it is documented across 1 model: Prowler.
What are the most common causes of P0758?
The most common causes of P0758 are: Faulty shift solenoid B, Damaged, shorted, or open solenoid wiring/connector, Low or contaminated transmission fluid, Clogged or worn valve body passages, Internal transmission electrical (harness) fault, Faulty transmission control module (less common). The specific cause varies by vehicle.
How much does it cost to fix P0758 on a Chrysler?
Published repair estimates on Chrysler range from $300 to $900 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
