Restore Peak Performance to Your 1997 GM Vehicle
Is your 1997 Pontiac Trans Sport, Chevrolet Venture, or Oldsmobile Silhouette running poorly? Are you battling a persistent Check Engine Light, experiencing sudden stalling, rough idling, or a noticeable drop in fuel economy? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your vehicle’s engine and transmission. This replacement PCM, part number 16217058, is the definitive solution to restore your vehicle’s reliability and drivability. We take the guesswork out of the repair by programming the module specifically for your vehicle using your VIN. It arrives ready for installation, loaded with the latest GM factory software updates to ensure optimal performance.
From the Diagnostic Bay
We had a 1997 Chevy Venture come into the shop with a complaint of intermittent stalling and a no-start condition that would happen without warning. The customer had already replaced the fuel pump and crank sensor, but the problem persisted. After hooking up our scanner, we noticed communication with the PCM was dropping out randomly. A visual inspection revealed nothing obvious, but a wiggle test on the main PCM harness connector would cause the engine to stumble. Before condemning the expensive module, we checked the power and ground pins at the connector. We found a corroded ground wire about six inches back from the plug. After repairing the wire, the Venture ran perfectly. This is a crucial reminder: always verify power, grounds, and wiring integrity before replacing a PCM. However, when those check out and symptoms point to the module, a properly programmed replacement like this one is the correct and final repair.
Common Symptoms of a Failing PCM
A faulty PCM can manifest in various ways, often mimicking other component failures. If your vehicle is exhibiting several of the following symptoms, the PCM is a likely culprit. This replacement 1997 Trans Sport PCM is designed to correct these issues and get you back on the road with confidence.
- ✔ Check Engine Light: The most common indicator. Codes related to internal module failure (like P0600-P0606), sensor circuits, or communication errors often point to the PCM.
- ✔ Engine Stalling or Misfiring: The PCM may fail to correctly command fuel injectors or ignition coils, leading to a rough-running engine that stalls unexpectedly.
- ✔ No-Start Condition: If the PCM is completely unresponsive, it cannot activate the fuel pump or ignition system, preventing the engine from starting.
- ✔ Poor Fuel Economy: Incorrect air/fuel mixture calculations can cause the engine to run too rich or too lean, drastically reducing your MPG.
- ✔ Erratic Automatic Transmission Shifting: The PCM also controls transmission shift points. A faulty module can cause harsh shifting, delayed engagement, or getting stuck in one gear.
- ✔ Failed Emissions Test: A malfunctioning PCM cannot properly manage the engine’s emissions systems, leading to an automatic failure at the testing station.
Plug-and-Play Installation with VIN Programming
Don’t waste time and money at the dealership. We simplify the repair process. When you order, you provide us with your vehicle’s 17-digit VIN. Our technicians then use this information to load the precise factory calibration for your specific make, model, and engine. This ensures that all systems communicate correctly from the moment you install it. This 1997 Trans Sport PCM arrives at your door ready to be installed, eliminating the need for expensive programming tools or a trip to a specialist.
Installation is straightforward for a DIY mechanic. Typically, the PCM is located in the engine bay, often near the air filter housing or firewall. The process involves disconnecting the vehicle’s battery, carefully unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in its place. After reconnecting the battery, your vehicle will be ready to go. In some cases, a simple security relearn procedure may be necessary, which can usually be done without any special tools.

Frequently Asked Questions
Do I need to have this PCM programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive with the correct software for your specific vehicle, ready for installation.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific car. It tells us everything we need to know about its factory options, engine, transmission, and emissions equipment. Providing the VIN allows us to load the exact GM calibration for your vehicle, ensuring perfect compatibility.
Where is the PCM located on my 1997 Trans Sport?
On the 1997 Pontiac Trans Sport and its sister vans (Venture, Silhouette), the PCM is typically located in the engine compartment, inside the air cleaner assembly box. You will need to open the airbox to access the module and its connectors.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM, then yes, this replacement part will resolve the issue. However, if the light is on due to a faulty sensor, wiring, or other component, that separate issue will still need to be addressed.
Is any additional setup required after installation?
In most cases, the module is plug-and-play. Some GM vehicles may require a security relearn procedure (also known as a CASE relearn) to sync the new PCM with the vehicle’s anti-theft system. This can typically be performed without special tools and instructions can be readily found online or in a repair manual.
