I have a Chevy Equinox 2008 3.4L Auto Trans. 121k miles. When I shift into reverse gear, I hear and feel a loud rumbling noise. This occurs only in reverse gear, all other gears shift correctly without issue. I have two “plausible” theories as to what this might be: First, the reverse gear is not fully engaging. Or second, in shifting to reverse gear I reversed time itself back to when Lucifer was cast from heaven and have unintentionally opened a door to hell’s dimension summoning a rage demon to torment my transmission… What do you guys think the root cause is? ---

My first thought is Original Sin. ---

When you shift into reverse, the engine twists in the opposite direction. If there’s worn engine/tranny mount, it may be opening up an exhaust leak. Tester ---

Google to find the TSB for r,3rd, and 5th gears fails to engage. 09-07-30-012F. Caused by broken clutch plate. Might be related. If that’s the problem, ask the dealership if there’s an extended warranty for a broken clutch plate. ---

Yes, I read the post. That’s why I mentioned the TSB affecting **R,** 3rd, and 5th. ---

George is probably right with this. The waveplate in these transmissions are notorious for cracking p, and failing. My daughted replaced one in a Acadia this year ( same motor and transmissions ) $4500 later … ---

I wouldn’t say I’m right or wrong, just that this is important info for the poster to be aware of.
