To be certain, you need to:
* Identify the exact transmission in both vehicles: The model number (e.g., 4L60E, 4L80E) is crucial. Look for it on a tag on the transmission itself.
* Compare transmission specifications: Once you have the model numbers, research the specifications of both transmissions online. Look for differences in physical dimensions, bolt patterns, and input/output shaft configurations.
Even if the model numbers appear similar, subtle differences can prevent a direct swap. It's best to consult a transmission specialist or a mechanic experienced with these vehicles before attempting this swap. A simple mismatch could lead to serious drivetrain damage.
