Bought a 2010 750Li with 131k miles knowing it has a bad transmission. First car wouldn't even go into gear. No fluid. I had mechanic change all the "mechatronics sleeves and refill with fresh fluid. Car now drives but it kicks you in the butt(on acceleration and deceleration) after a few shifts and goes into limp mode. My question is do I need a transmission or can I get away with just the valve body being rebuilt? I found a transmission I can pick up, but I have to make a decision while it's still available. Posting the Codes below. Bite the bullet on a Used Trans or go the cheaper route and re-do the valve body? Your input and suggestions are appreciated.
