These guys know there business on the site!!!!... Love the site and everyone's help thank you!!! Happy Easter!Make sure that the transmission support bracket is still attached to either the front corner or on some mowers the front of the transmission. Sounds like the tranny is rocking back and forth . If you find that the support bracket has come loose then also look at the frame tabs that connect the frame with the transmission axles. they will be cracked and will require repair.
