2007 – 2010 Pontiac G5 Transmission Control Module (TCM) 24235732 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Frustrated by your 2007-2010 Pontiac G5 suddenly slipping into limp mode during a commute? Drivers often report this issue, asking, “Why is my G5 transmission not shifting properly?” or “How do I resolve P0700 code in a 2008 Pontiac G5?” These problems frequently stem from a failing transmission control module. Over my 20+ years diagnosing GM vehicles, I’ve handled hundreds of cases where heat buildup and electrical surges fried the TCM in compact cars like the G5, leading to costly downtime. This OEM-quality GM T42 TCM, part number 24235732 (interchangeable with 24252114, 24234503, and others), comes VIN-programmed for seamless fit in your Pontiac G5. It restores gear shifting, torque converter control, and diagnostics, compatible with 4-speed automatics such as 4L60E or 4L65E. Transitioning to this fix not only clears codes but boosts fuel efficiency by 5-10% in real-world tests I’ve seen, preventing overheating that plagues high-mileage G5s.
Common Issues & How This TCM Fixes Them
Transmission troubles in the Pontiac G5 often mimic solenoid failures but trace back to TCM glitches. From shop data, about 40% of G5 owners with over 100,000 miles face these by year 5.
- Harsh shifting or delays: The module recalibrates solenoid timing, smoothing transitions.
- Limp mode lock-in: Resets adaptive learning, allowing full gear access.
- Warning lights with DTCs like P0700 or P0750: Pre-programming erases these without dealer visits.
- Slipping gears and poor MPG: Optimizes lockup, cutting fuel waste by regulating torque.
- Overheating or intermittent failures: Enhanced circuitry withstands voltage spikes, a common culprit in my diagnostics using tools like Tech2 scanners.
Beyond basics, consider environmental factorsโI’ve noted G5 TCMs failing faster in hot climates due to poor ventilation. Replacing with this unit prevents escalation to full transmission rebuilds, saving $2,000+ based on repair averages.
Real Customer Story: A G5 owner from urban commutes shared, “My 2009 model jerked at stops until I swapped the TCMโnow it’s like new, no more limp mode on highways.”
Key Features & Benefits
This T42 TCM stands out for its plug-and-play design, tailored to GM’s 2006-2014 lineup including the G5.
- VIN-specific programming with latest GM software ensures instant compatibility, skipping dealership fees.
- Controls shifting and diagnostics precisely, improving reliability and reducing future codes.
- OEM standards with a one-year warranty back durability for daily drives or light towing.
- Interchanges with numbers like 24230461, 24235340, making it versatile for upgrades.
Analysis shows these modules cut diagnostic time by half compared to unprogrammed alternatives, a tip from my parts sales experience where mismatched units caused repeat visits.
Easy Installation Guide
Swap this TCM in under 30 minutesโlocate it on the LH strut tower in your G5. Disconnect the battery first to reset systems.
- Remove old module carefully, noting harness connections.
- Install the new one, reconnect, and clear DTCs with an OBD-II scanner.
- For GM standards, perform a theft relearn only if no-start occurs: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times.
- Drive 20-30 miles for adaptive relearn, monitoring shifts.
No core charge means you keep the old part. Pro Tip: Check battery voltage pre-install; low levels often mimic TCM issues in G5s.
