I have this 1993 F150 Lightning with 08 5.3L and 6L90E, Truck drives and runs great, just looking if it can be improveed.
Is there any gain locking the TCC on a WOT run? in what gear can i lock it and will it be better? and lets say i lock it at 2nd gear, from what rpm is ok to lock it and it will unlock by itself when shifting? im running
