I have 109k on my truck right now. Going to change the fluid this weekend. I did a bit of towing about a month ago, had it in towhaul, with my tow tune on. After taking the trailer off the truck I noticed that the tranny started to shift a bit hard. Not neck breaking hard, but you can definatly tell when it shifts. Fluid seems to be full. This weekend I am going to pull the pan, change the filters and put some Amsoil in it. Any sujestions as to why its shifting hard? Any input is greatly appreciated. Thanks

TCM will learn down in a couple of days and it will shift normal.

Ok thank you. It has been about a month and it is still shifting a bit hard, I will let you know how it does after I change the fluid and filters....thanks Mike

well my bumbass found out that my tranny takes 21qts of fluid.....umm, no Amsoil for me, too rich for my blood. I checked the fluid, its full, and its still very red. Still shifting a bit hard sometimes. I didnt change the fluid. Any sujestions?
