Code P0735 2014 Chevrolet Silverado Description
The TCM provides a 9 V reference circuit and a signal circuit to each of the sensors. As the 1-2-3-4-5-6 clutch piston housing and transmission output shaft or transfer case output rotates, the sensors produce a signal frequency based on the teeth on the reluctor wheel. The TCM calculates the transmission gear ratio based on the speed sensor signals and compares the calculated gear ratio to the commanded gear ratio.
The Diagnostic Trouble Code (DTC) will be set when the TCM detects the calculated gear ratio with 5th gear commanded differs from the known 6th gear ratio for 2 s.
What are the Possible Causes of the DTC P0735 2014 Chevrolet Silverado?
- Low transmission fluid level
- Shift solenoid mechanical fault
- Faulty Turbine Sensor
- Faulty Output Speed Sensor
How to Fix the DTC P0735 2014 Chevrolet Silverado?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

2. What are the common symptoms of the P0735 code on a 2014 Silverado?
Symptoms may include harsh or delayed shifting, transmission slipping, reduced fuel efficiency, and the check engine light or transmission warning light being illuminated.
3. What causes the P0735 code on a 2014 Chevrolet Silverado?
Common causes include low or dirty transmission fluid, a faulty transmission solenoid, worn clutch components, internal transmission damage, or problems with the transmission control module (TCM).
4. Can I keep driving my 2014 Silverado with the P0735 code?
Driving with the P0735 code is not recommended as it may worsen transmission damage, lead to unsafe driving conditions, or cause the vehicle to go into limp mode.
5. How do I fix the P0735 code on my 2014 Silverado?
Repairs may include checking and replacing the transmission fluid, inspecting and replacing damaged solenoids or clutch components, repairing internal transmission issues, or reprogramming or replacing the TCM.
6. How can low transmission fluid lead to the P0735 code?
Low transmission fluid can cause improper hydraulic pressure, leading to incorrect gear ratios and triggering the P0735 code.
7. How much does it cost to repair the P0735 code on a 2014 Chevrolet Silverado?
Repair costs vary depending on the issue. Transmission fluid replacement may cost $100–$200, while internal transmission repairs or TCM replacement could exceed $1,000.
8. How can I diagnose the P0735 code on my Silverado?
Start by checking the transmission fluid level and condition, then use an OBDII scanner to identify additional trouble codes. Perform a visual inspection of wiring and solenoids, and test the TCM if necessary.
9. Could a faulty speed sensor cause the P0735 code?
Yes, a malfunctioning speed sensor can provide inaccurate data to the TCM, leading to incorrect gear ratio calculations and triggering the P0735 code.
10. Is it possible for the P0735 code to return after repairs?
Yes, the code may reappear if the root cause isn’t fully addressed, such as unresolved internal transmission issues or an intermittent electrical problem.
