I have a ZF6 trans out of a 99 7.3 Super Duty 2x4. Truck I pulled it out of has 186k on the clock.. I am assuming it's the original trans.. It shifted smooth through all gears no problem no grinding good working condition.. Located in western Maryland.. would be willing to drive a couple hours or so to meet someone if needed.. looking for $1,000, May consider trades.. Let me know what you got.. I am looking for a set of doors for a crew cab power windows/ locks.. if you pm me your number I can text you pics.. Thanks
