Buddy Neal uses Lucas Transmission Fix in 1998 Dodge Pickup 4WD

Never even heard of Lucas Trans fix before, I am not even close to being a menchanic, but had a problem shifting. Truck was "Late Shifting" I guess. Not slipping, but I had to let off the gas a lot to get it to shift into next gear. Been doing this for a year I guess. I heard about an additive that could be put into transmission that could help, but no product name. Went to AutoZone nearby and they suggested this one. Immediately, I mean right then as I drove off the lot, not one LAG or late shift. I will tell everyone I know that even thinks they may have this problem to give this a try. I am completely happy with this additive.
