Hello everyone!

I have just finished changing the filter and fluid in my transmission (4HP22) and am surprised at the amount of fluid that it took to bring it up to the full mark. A little over 6.5 quarts...which is double the amount as advised by the Bentley and Owner's manuals. Has anyone ever drained that much fluid? I let it drain for about two days with the front of the car on jackstands (was sourcing parts and time). Could this have contributed to so much fluid being removed? The car behaves so much better now. Incredible improvement in shift quality and performance. Thanks in advance for your opinions.

Best regards.
