Mark Jones Recommends Lucas ATF Conditioner for the amazing results on his 2005 Ford Super Duty TorqShift Transmission

We recently purchased a 2005 Ford F350 Super Duty 6.0 Powerstroke Diesel with the 5R110W, TorqShift transmission with 90K miles on it.  Shortly after the purchase we noticed that the  transmission was leaking fluid from a hairline crack in the transmission case.  The dealer replaced it with a \used\ unit and when it was returned to us it did not seem to perform as well or shift as smoothly as did the original leaking transmission. 

I added (1) 20 ounce bottle of Lucas Oil's Automatic Transmission Fluid Conditioner and the results are nothing short of amazing.  It performs so much better now and just feels so much more positive in the up-shifts and down-shifts.  Even better than the original leaking transmission. 

Thank you for producing such a wonderful product. I am not one that looks to use additives much but I would definitely recommend this to others. 

Thank you again,
Mark R Jones
