Currently in my 2003 4WD dually, shifts kinda hard when warmed up. Have another one going in in about 2 weeks or so, come drive while still in there. Rig also has a SBC semi custom OFE/FE set up in it , may sell that also. Also have another 5600 that seems to have lost 3rd and 4th gear, however after replacing, seemed to have it on bench. Asking $2500 apiece on trans, $700 for clutch. Located in Las Vegas, Nv. May be able to help with delivery within a days drive of here for a small fee. (702) 498-1368
