* Transmission Type: You need to ensure both vehicles have the *exact same* transmission type (e.g., 4L60E, 4L80E). Even slight variations within the same family of transmissions can cause compatibility issues. Check the transmission identification numbers on both transmissions for an exact match.
* Transfer Case (if applicable): If either vehicle has a 4WD system, the transfer case needs to be compatible as well. Different gear ratios and interfaces can prevent a proper fit.
* Engine: The engine and transmission need to be matched. An incorrect pairing will result in shifting problems or even damage.
* Wiring Harness: The wiring harness for the transmission may need modification or replacement, as the connectors may differ slightly between model years.
* Computer Control: The PCM (Powertrain Control Module) might need to be reprogrammed or replaced to work correctly with the new transmission.
In short: While *possible*, it's not a guaranteed easy swap. It's highly recommended to verify the exact transmission types (including the identification numbers) of both vehicles *before* attempting any work. Even then, professional installation is strongly advised to avoid potential damage to the vehicle. A mechanic can determine if the swap is feasible and identify any potential compatibility issues.
