"what are some common problems with the 1988 Chrysler New Yorker transmission?"

Question

Accepted Answer

Based on my research, here are the most common transmission problems with the 1988 Chrysler New Yorker:

**Primary Issues with the A604/Ultradrive Transmission:**

1. **Limp Mode Problems** - The most frequent issue where the transmission suddenly locks into 2nd gear (called "limp-home" mode). This happens when the transmission computer detects sensor problems and defaults to a safe mode to prevent damage.

2. **Poor Shifting Quality** - Rough, harsh, or erratic shifting between gears, often caused by:
   - Faulty input/output speed sensors
   - Solenoid pack failures
   - Low or contaminated transmission fluid

3. **Transmission Slipping** - Engine RPM increases but the car doesn't accelerate proportionally, indicating:
   - Worn clutch plates
   - Low hydraulic pressure
   - Internal mechanical wear

4. **Sensor Failures** - The A604 relies heavily on electronic sensors that commonly fail:
   - Throttle position sensor
   - Vehicle speed sensor
   - Transmission temperature sensor

5. **Fluid-Related Issues** - These transmissions are very sensitive to fluid quality and level:
   - Requires specific ATF+3 or ATF+4 fluid
   - Contaminated or burnt fluid causes shifting problems
   - Overheating due to inadequate cooling

6. **Solenoid Pack Problems** - The solenoid pack controls gear shifts and commonly fails, causing harsh shifting or failure to shift properly.

**Prevention Tips:**
- Regular fluid changes with the correct ATF+3/+4 fluid
- Address any sensor issues immediately
- Keep the transmission cool with proper maintenance of the cooling system
- Have the transmission computer scanned for codes if any shifting issues appear

The good news is that many of these issues are well-documented and repairable, though the A604 transmission does require attentive maintenance to keep it running reliably.
