* On the Transmission Case: The most likely place is cast directly into the transmission case. This will be a series of letters and numbers. You'll probably need a flashlight and maybe even a wire brush to clean off any grime to make it legible. The transmission is located under the vehicle, near the engine. Look for a relatively flat surface on the side or top of the transmission casing.
* Service Manual: Consult a repair manual specific to your 1996 Chevy Tahoe with the 5.7L engine. The manual should have diagrams showing the transmission location and possibly indicating where the ID tag is located.
* Vehicle Identification Number (VIN): While the VIN itself won't directly give you the transmission code, it can be used to find the build sheet through a third-party service or a dealer, potentially providing this information.
Important Considerations:
* Access: Getting to the transmission case might require getting under the vehicle. Use jack stands for safety. Never work under a vehicle supported only by a jack.
* Cleanliness: Dirt and grime can obscure the numbers.
* Multiple Transmissions: The 1996 Chevy Tahoe 5.7L might have had different automatic transmission options. Knowing the original equipment will make finding the right code easier. This information might be found on the original window sticker (if available) or in the vehicle history report.
It's a bit of a hunt, so be prepared to spend some time looking. Using a repair manual as a guide will greatly increase your chances of success.
