What could cause the center support to break? Anyone know these trannies well? As some of you know my newly rebuilt tranny went. I talked to the shop this morning and they said it was the center support. She informed me that she wasn't pointing any fingers but that this is usually caused by doing neutral drops! My b/f was test driving the truck, after we put the lift/tires/shocks on the truck. He swears to me that he didn't pounce it, and was driving it normally. Said he was going a little fast, came to a stop, went to go and it made a snap noise. Has anyone else had one of these break? Help me... I'm very curious!!
