Ford Transmission Shudder Fix

After being to the dealer three times for a shudder complaint and being told there's nothing wrong with it, this 2014 Ford Explorer was brought to me. I determined the shudder to be caused by either clutch slippage or chattering in 3rd and 5th gears. At this point there are only a few options. Replace the transmission, overhaul the transmission, or try changing the fluid and adding a Lucas transmission fix additive, which is what we did in this video. And it worked!
