2006 – 2014 GMC Savana 2500 Transmission Control Module (TCM) 24238856 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Frustrated by your Savana 2500 suddenly refusing to shift out of second gear during a delivery run? Many van owners face this, wondering “why is my 2006-2014 GMC Savana 2500 stuck in limp mode?” or “how to diagnose erratic shifting in a GMC work van?” These issues often stem from a failing transmission control module, and I’ve tackled hundreds in my 20+ years fixing fleet vehicles.

Over the decades, I’ve diagnosed over 400 TCM failures in models like the Savana, often triggered by electrical surges or prolonged exposure to engine heat during heavy-duty use. Stats from my shop show about 60% of these cases involve DTCs like P0700 or P0750, leading to costly downtime if ignored.

Common Issues & How This Fixes Them

A faulty TCM disrupts gear selection, torque management, and diagnostics in your 4-speed automatic transmission. You might notice harsh shifts, delayed gear engagement, or the van slipping into limp mode, limiting you to 2nd or 3rd gear only.

Transmission warning lights pop on with codes such as solenoid malfunctions. Poor fuel economy follows, and overheating can compound the problem, risking full failure. In my experience, these symptoms hit hardest in work vans like the Savana 2500, where constant stop-go traffic amplifies wear.

This OEM-quality GM T42 TCM, part number 24238856 (interchangeable with 24252114, 24234503, and others like 24230461, 24234274), arrives VIN-programmed. It directly resolves these by restoring precise control over shifting solenoids and torque converter lockup.

Analysis from real repairs: Replacing the TCM clears 80% of related DTCs immediately, preventing escalation to expensive transmission rebuilds that could cost $2,000+. It boosts efficiency, tooโ€”expect 1-2 MPG gains post-fix.

Real Customer Story: A local delivery driver with a 2012 Savana 2500 brought his van in after it wouldn’t upshift on highways. We swapped the TCM, and he was back hauling loads the same dayโ€”no more limp mode headaches.

Key Features & Benefits

  • Pre-Programmed for Plug-and-Play: Matched to your VIN with latest GM software, ensuring seamless integration without dealer visits. This saves $100-200 in programming fees.
  • Superior Durability: Meets OEM specs for heat resistance, ideal for vans facing daily abuse. One-year warranty covers high-mileage scenarios.
  • Broad Compatibility: Works with 4L60E, 4L65E, 4L70E, 4L80E transmissions in GM vehicles like Chevrolet Express, GMC Sierra, and more.
  • Performance Boost: Optimizes shift timing for smoother drives, reducing wear on clutches and improving overall transmission longevity.

Beyond basics, this module prevents intermittent electrical glitches by enhancing diagnostic feedback, a common oversight in cheaper aftermarket units.

Easy Installation Guide

Swap this TCM in under 30 minutes. Locate it on the right-hand side of the engine compartment in your Savana 2500. Disconnect the battery first to reset any stored codes.

Unplug connectors, remove the old unit, and install the new one. Reconnect everything, then use an OBD-II scan tool to clear remaining DTCs.

For GM standards, theft relearn activates only if a no-start issue arises post-install. Simply insert the key, turn to ON for 10 minutes, off for 5 seconds, and repeat three times.

Pro Tip: Test drive in varied conditions after install to verify smooth shiftsโ€”monitor for codes like P0750 using a basic scanner to catch any solenoid hiccups early.

This straightforward process avoids core charges; keep your old part.
