Here's why:
* "V6 Chevy" is too general: Chevy makes many vehicles with V6 engines, from small cars to trucks.
* Suburban models vary: Over the years, the Suburban has been paired with many different transmissions, depending on the year and engine.
To help me answer your question, please tell me:
* What specific V6 Chevy vehicle are you interested in? (e.g., Silverado, Colorado, Malibu, etc.)
* What year is the Suburban you're comparing it to?
Once I know these details, I can give you a precise answer about whether those vehicles share the same transmission.
