First to second gear strange hits
 

Hey there!
This morning gave me a new expirience. When my 4L60E shifts from first to second gear, something is hitting strongly in cup holder area. It happens when I drive normally, but when I drive very slightly RPM goes to 1800 slowly, then it shifts without hitting.
Any idea what it could be? Drive shaft or maybe drive shafts centre support or yoke?


Thank you!

Trans mount is broken.

Right in the ten! Thank you.
Yesterday i was at inspection pit and noticed that rubber mount is splitted on two separate pieces, so I ordered a new one. I think it will not be very difficult to replace it...
