I have been using the Lucas Oil Additive in the 06 CTD since the first oil change (Jason got me hooked on it) and I love it. Well the tranny in the Mac tool Truck has been leaking worse and worse from the cooler. Well the other day it cracked open bad... Like going through 2 quarts of Tranny fluid a day. I limped it through the end of the week (no one around stocked a replacement) I was having a problem with the TC locking and unlocking in OD at the end of Friday on the way home with 5 miles to go and no tranny fluid in site I just pushed on. Well after getting the tranny coolor in thi smorning I decided to dump in a bottle of the Lucas Tranny Additive in case I did any damage. Well the TC was fixed (I think that was more of a low fluid problem) but th ebig difference was in the trannys performance it was VERY obvious the difference. The tranny feels Tighter and shifts smother. I think this thing has had some slip from the day I got it because it seems to pull harder. Maybe it is just me. I would recomend this to ANYONE you wants to keep there tranny in top shape. I'm picking up a bottle for the dodge this weekend!

Hope it works out for you.
On my 01 Dodge I put 1 qt. of Lucas transmission Additive when doing a fluid & filter change. The tranny slipped like crazy. I had to do 2 fluid changes to flush it out. Hope you have better luck with it than I did.
