Get Your Work Van Back on the Road, Fast
If your 2006-2014 GMC Savana 1500 is your workhorse, you can’t afford downtime. When the transmission starts acting upโslamming into gear, refusing to shift, or throwing a check engine lightโit’s not just an annoyance; it’s a threat to your livelihood. In my 20+ years of diagnostics, I’ve seen countless work vans sidelined by these exact issues, and the culprit is almost always a failing Transmission Control Module (TCM). This isn’t just a part; it’s the solution to get you back on schedule and earning again.
Is Your Savana 1500 Exhibiting These Symptoms?
A faulty TCM can manifest in several ways. If you’re experiencing any of the following, it’s time for a replacement:
- โ Harsh, banging shifts or delayed gear engagement, especially when the van is cold.
- โ The vehicle is stuck in “limp mode,” usually in 2nd or 3rd gear, with severely limited power.
- โ The Check Engine Light is on with transmission-specific Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid circuit faults.
- โ Complete failure to upshift or downshift, making highway driving impossible.
- โ A noticeable drop in fuel economy as the transmission operates inefficiently.
Expert Pro Tip: Check This Before You Replace
Before condemning the TCM, I always perform a simple check that has saved customers hundreds of dollars. On these GM platforms, a failing ignition switch or a weak battery can cause voltage drops that mimic TCM failure. The module loses communication intermittently, triggering error codes and erratic shifting. Ensure your battery holds a steady charge above 12.4V and that there’s no wiggling or play in the ignition key cylinder. It’s a 5-minute check that can prevent a misdiagnosis.
