P2714 on 2016-2019 Chevrolet Spark: Causes, Fixes, and TSB Details

What's Unique About the 2016-2019 Chevrolet SPARK

Unlike many vehicles where P2714 might point to a failed solenoid or valve body, on the Chevy Spark, GM has identified a very specific and common failure point. A Technical Service Bulletin (TSB 19-NA-053) pinpoints the cause as debris from within the valve body contaminating the Transmission Fluid Pressure Switch. This makes diagnosis more direct than on other platforms, as the issue is well-documented by the manufacturer and points to a single, known problematic part rather than general transmission failure. The TSB was updated in May 2020 to cover models from 2014-2020.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• Check Engine Light (MIL) is on
• Poor transmission performance or hesitation, especially when accelerating from a stop
• Harsh, jerky, or delayed shifting
• Transmission slipping (engine RPMs rise without an increase in speed)
• Vehicle may enter 'limp mode'
• Engine may stall or shut off intermittently

Most Likely Causes

1. Contaminated Transmission Fluid Pressure Switch 🔴 High Probability → Shop Transmission Assembly According to GM Technical Service Bulletin 19-NA-053, debris originating from the valve body can contaminate the switch, causing it to malfunction and trigger P2714. This is the most common and well-documented cause for this specific code on the Spark.
   How to confirm: A technician will verify the code is present. Following the TSB, the diagnostic procedure is to clear the code and perform a road test. If the code returns, the pressure switch is the presumed culprit and should be replaced.
   Typical fix: Replace the Transmission Fluid Pressure Switch. This involves dropping the transmission pan, removing the filter, and replacing the switch on the valve body. The transmission filter and fluid should always be replaced at the same time.
   Est. part cost: $120-$135
2. Low or Dirty Transmission Fluid 🟡 Medium Probability → Shop Transmission Assembly The Jatco CVT7 in the Spark is sensitive to fluid condition. Old, degraded fluid can contribute to the formation of debris that clogs the pressure switch and other valve body components. Driving with low fluid can also cause pressure-related codes.
   How to confirm: Check the transmission fluid level and condition. Note that the Spark CVT does not have a traditional dipstick, so this must be checked via a fill/check plug by a professional.
   Typical fix: Perform a transmission fluid drain and fill using the correct CVT-specific fluid. If the fluid is very dirty or the code is already present, this should be done in conjunction with replacing the pressure switch.
   Est. part cost: $80-$120 for fluid

Rare But Worth Checking

• Faulty Transmission Valve Body: → Shop Transmission Valve Body While the TSB points to the switch, a severely worn or internally clogged valve body could be the source of the debris. If replacing the switch doesn't solve the issue, the valve body itself may be the problem, which is a much more expensive repair.
• Wiring or Connector Issues: Damage to the internal transmission wiring harness leading to the pressure switch or an external connector issue could cause this code, but it's far less common than the switch contamination.
• Failed Transmission Control Module (TCM): → Shop Transmission Assembly A faulty TCM is a rare possibility and should only be considered after all other mechanical and electrical components have been thoroughly tested and ruled out.

Diagnosis Steps

1. Verify the P2714 code is present using a professional OBD-II scanner.
2. Check for any other related transmission codes, especially P0871.
3. Consult TSB #19-NA-053 for the 2014-2020 Spark.
4. Clear the DTCs and perform a road test to see if the code returns.
5. If the code returns, the next step is to replace the Transmission Fluid Pressure Switch as per the TSB.
6. Inspect the transmission fluid level and condition. The fluid should be the correct type (CVT-specific) and not burnt or full of debris.
7. Drop the transmission pan and inspect for excessive metal shavings, which would indicate a more severe internal failure.
8. Remove the transmission filter to access the pressure switch on the valve body.
9. Replace the Transmission Fluid Pressure Switch (GM Part #25205266, which supersedes #25202299).
10. Install a new transmission filter and pan gasket.
11. Reinstall the transmission pan and refill with the correct amount of new, manufacturer-specified CVT fluid.
12. Clear the code and perform another road test to confirm the repair.

Parts You'll Likely Need

• Transmission Fluid Pressure Switch (OEM #25205266) — This is the specific part identified by GM in TSB 19-NA-053 as the cause for code P2714 on the Chevrolet Spark. It is the superseding part number for the original, 25202299.
  Trusted brands: GM Genuine Parts, ACDelco
  OEM price range: $120-$135
• CVT Transmission Fluid (OEM #ACDelco 19431499 (CVT Fluid)) — The transmission must be drained to perform the repair and refilled with new, correct-spec fluid. Using the wrong fluid can cause severe damage.
  Trusted brands: ACDelco
  OEM price range: $20-$30 per quart
  Aftermarket price range: $15-$25 per quart
• Transmission Filter Kit (with Pan Gasket) (OEM #ACDelco TF923 or TF930 (verify by VIN)) — The filter must be removed to access the pressure switch, so it should be replaced as part of the service to ensure a clean system.
  Trusted brands: ACDelco, Fel-Pro (gasket)
  OEM price range: $30-$50
  Aftermarket price range: $20-$40

Related Codes That Often Appear With This One

• P0871 — This code for 'Transmission Fluid Pressure Switch 'C' Circuit Range/Performance' is often set alongside P2714. TSB 19-NA-053 explicitly covers both codes, as they stem from the same root cause: a contaminated pressure switch.

Technical Service Bulletins (TSBs) & Recalls

• PIP5521B: A preliminary bulletin that directs technicians to reference TSB 19-NA-053 for codes P0871 or P2714.
• 19-NA-053: The primary TSB for this issue, last updated in May 2020. It identifies the cause as a transmission fluid pressure switch contaminated by debris from the valve body and provides the procedure to replace it to fix codes P0871 and P2714 on 2014-2020 Sparks.

Platform-Specific Known Issues

• The CVT7 transmission (RPO codes M4M, MR8) used in this generation of Spark is a Jatco JF015E model. This transmission design features pulleys located above the main oil sump to reduce drag, but it is known to be sensitive to fluid contamination, which directly leads to this P2714 code via the pressure switch.
