P0715 on Chrysler by model: symptoms, diagnosis and fix
The New Yorker's A604 (41TE) 4-speed automatic was one of the first electronically controlled transmissions and is notorious for premature failure. The solenoid pack, input/output speed sensors, and clutch packs wear out, causing erratic shifting and complete failure.
Common Symptoms
- Erratic shifting
- Stuck in second gear limp mode
- Delayed engagement into drive or reverse
- Slipping under load
- Check engine light
- Transmission shudder on acceleration
How to Fix
Replace the solenoid pack and speed sensors for early symptoms. Once slipping occurs, a full rebuild or remanufactured transmission is required. Use only ATF+4 fluid — other fluids accelerate clutch wear.

The LeBaron uses the Chrysler A604 (41TE) 4-speed electronically-controlled automatic transaxle. This was one of the first fully electronic automatics and its solenoid pack is the primary failure point. The solenoids develop internal leaks and electrical failures, causing erratic shifting, no-shift conditions, and limp mode (locked in 2nd gear). The transmission controller can also fail. The A604 was so problematic that Chrysler extended warranty coverage on early units.
Common Symptoms
- Transmission stuck in 2nd gear (limp mode)
- Check engine light with P0700 and P07XX codes
- Harsh or erratic shifting between all gears
- No upshift from 2nd gear
- Transmission bangs into gear from Park
How to Fix
Replace the solenoid pack assembly (located in the valve body) with an updated unit. The solenoid pack is accessible by removing the side pan. A remanufactured solenoid pack from TransGo or Rostra is $150-250. If the transmission is in limp mode, scan for codes first — many limp mode events are caused by a speed sensor or input/output shaft sensor failure rather than the solenoid 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 P0715 mean on a Chrysler?
P0715 stands for "Input/Turbine Speed Sensor Circuit Malfunction." P0715 indicates a malfunction in the input/turbine speed sensor circuit of an automatic transmission. This sensor measures how fast the transmission's input (turbine) shaft is rotating, which the transmission control module uses—alongside output speed—to calculate gear ratios and command smooth, properly timed shifts. When the signal is missing, erratic, or out of range, this code sets. Symptoms often include harsh or erratic shifting, incorrect shift points, no speedometer-related transmission data, or the transmission dropping into a limp/fail-safe mode. On Chrysler it is documented across 2 models: New Yorker, LeBaron.
What are the most common causes of P0715?
The most common causes of P0715 are: Faulty input/turbine speed sensor, Damaged wiring or connector at the sensor, Low or contaminated transmission fluid, Corroded or loose connector terminals, Open or short in the sensor circuit, Internal transmission wear or debris affecting the sensor, Faulty transmission control module (less common). The specific cause varies by vehicle.
How much does it cost to fix P0715 on a Chrysler?
Published repair estimates on Chrysler range from $200 to $2,500 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.
