audi q7 2010 after engine change the car will not drive even after shifting into gear
"I have a 2010 Audi Q7. After replacing the engine, the car starts but won’t move when I shift it into gear (Drive or Reverse). The gear engages, but the car doesn’t move at all. What could be causing this?"

That's a pretty open question since you replaced the motor, which requires all electrical connectors to be undone, and would have separated the transmission/torque converter from it too. Most times when folks DIY a repair and the car don't work right afterwards, or at all, it turns out to be an electrical connector either not clicked in place or mixed up with similar connector.
I'd start by scanning the car to see if the scan tool can tell me anything (you didn't mention), and of course when you disconnect everything on the car it throws tons of fault codes related to that too. Gotta clear everything out then see what returns, if anything, just as part of the repair process.

Hi all, the connectors are all in place and good. I have scanned for hours, went through all connectors but I made my reach and I found someone saying I should check if there is any pressure in pipes, so I did so and there was non,e so that's the pump gone. I opened the transmission the full thing of the pump was gone; that's what needs replacing

Interesting. I was thinking perhaps the torque converter wasn't seated properly in the transmission. I did that once on an old C4 transmission (Ford), and it started fine, shifted fine, but didn't go anywhere. After separating the engine from the bell housing and adjusting the seat on the TC, I felt it slip in further to the input shaft, put everything back together, and it was good to go!
