DPF/cat delete transmission questions

[rksorrells]

I finally got around to ordering the dpf/cat delete kit with the H&S xrt pro from ptp. Looks like my parts will show up in time to do the conversion this weekend. I am really looking forward to this modification. I have been reading a lot of info concerning this mod and have a question regarding the transmission relearn process. I plan on running the mild tune, do i have to do the tranny relearn process? It would take me about 20 minutes to get to somewhere I can safely attain the 80mph runs that H&S recommends on their website, will i harm my transmission driving that far without doing the relearn process? Also, when I bought my truck it already had a K&N intake and filter on it, is this a sufficient enough upgrade to be able to run the higher tunes if I chose to in the future? Any opinions would be greatly appreciated. Thanks

You will be fine driving that far. You dont HAVE to do the tranny relearn. It will do it on its own but it take many miles, thats why the suggest doing the power runs to do it faster. As for the intake, you should be good since it is already on the truck. There are better systems in my eyes for diesel trucks, but why buy a different intake when you have one. If you wanted you could always look to see if there is a S&B or AFE filter that would fit on your K&N tubing.

I dont do a tranny relearn. I just drive normal and the transmission learns on its own.

I don't do the relearn either. I have done it a couple times and really can't tell the difference time wise for the relearning between the 2 ways.

Thanks for the great info. This really set my mind at ease.

I've retuned my truck several times testing out different settings, and I would strongly recommend doing the trans learn per H&S's instructions.

I wasnt able to do the full thing on one tuning session and the truck shifted pretty weird. I re-tuned and did the trans learn and it shifts much better.

You dont have to do a full 20-80 mph at WOT, just as long as you let it shift through the gears up into 5th under heavy acceleration.

You could always take the truck near the highway where you can do the re-learn, then tune it and then do your highway pulls to learn it properly.

I usually drive out to my relearn location and reprogram there on the side of the road, then do the relearn.
