You need to find your transmission type first. This can usually be determined by:
* Looking at your vehicle's documentation: Your owner's manual might specify the transmission type.
* Checking the VIN: Using your VIN, you can look up your Tahoe's specifications online through various automotive resources (like a parts website).
* Checking the transmission itself: The transmission type may be stamped somewhere on the transmission casing itself, but this requires getting under the vehicle and might be difficult to read.
Once you know the transmission type:
* Find a repair manual specific to your 2005 Chevy Tahoe and its transmission type. This is the BEST way to get an accurate location and procedure. A repair manual (Chilton, Haynes, or a factory service manual) will have diagrams and instructions.
Without a repair manual, looking under your vehicle (safely supported on jack stands!) and searching near the transmission pan is your only option. The drain plug will likely be a hex bolt or a similar type of fastener located on the bottom of the transmission pan. However, without knowing the specific transmission and using a manual as a guide, this is a risky approach.
Caution: Working under a vehicle is dangerous. Always use jack stands and follow proper safety procedures. If you're not comfortable working on your vehicle yourself, take it to a qualified mechanic.
