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.

I got identical problem, problem you can't just buy and replaced. Required to be reprogram for DME to communicated with new one. However, I used E-sys and reprogram or reflash the original software to my EGS, and seem to be a good fixed, Malfunctions never pop up again, and shift normal.
