Picked up a '86 GMC Jimmy with a cracked flexplate this week. Finally tore into it and found out why it cracked... there were only 3 bolts holding the tranny to the motor and only one was really close to being tight. Tranny had backed off on one side by 1/8-1/4 inch. So that put the tranny and motor at an angle to each other eventually cracking the flex plate. Notice the daylight showing between the block and the tranny. Also found the crossmember with 2 very loose bolts... Now I need to find 6 new bolts to hold the tranny on with... I think the ones that were in there were too long and did not hold the tranny tight to the block before bottoming out. They look longer than normal... Anyone know how long they should be?
