Transmission Shift Time Too Short (P0895)
Code P0895 indicates that the transmission control module (TCM) has detected that the time required to complete a gear shift is shorter than the expected calibrated range. This can be caused by low transmission fluid, a faulty shift solenoid, internal transmission wear, or a TCM software issue. The condition may lead to harsh shifts, slipping, or premature transmission failure if not addressed.
1. Symptoms You Will Notice
- Harsh or abrupt gear shifts
- Transmission slipping
- Check Engine Light illuminated
- Reduced fuel economy
2. Most Common Causes
- Low or incorrect transmission fluid level
- Contaminated or wrong type of transmission fluid
- Damaged or stuck shift control solenoid
- Faulty transmission speed sensor
- Internal mechanical issues (e.g., worn bands or clutches)
- Short or open in TCM wiring or connectors
- Transmission control module (TCM) software fault or damage
3. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Check transmission fluid level and condition; top off or replace if necessary.
Step 3: Inspect wiring and connectors to the shift solenoids and TCM for damage or corrosion.
Step 4: Perform a transmission solenoid resistance test and compare to specifications.
Step 5: If no issues found, update TCM software or replace TCM as needed.
