I don't know if this is the right place to post this, but I also have a 2001 F150 XLT super crew. I would like to upgrade the 4r70 auto transmission to a 5 or 6 speed auto. Is this a simple matter of the right tranny swap... Or am I moving into computer and wire harness territory? Plus transfer case, exhaust, drive shafts, etc... Maybe it would be cheaper to buy a new truck?
Exhaust has nothing to do with your transmission lol. And there is no 5 speed auto. The 4R70 was 4 speed plus overdrive (5 gears). The next transmissions in newer generations were 6 speed. The only 5 speed Ford made in these years was manual.
As for the Harley Davidson ECM, I'm going to say no because those models were supercharged and were programmed much different than the naturally aspirated trucks. They were designed for way more power and much different ignition timing as compared to any other F-150 model.
The 2001 F150 Harley Davidson edition was not supercharged.

Ford made many 5 speed auto transmissions that have been modified for use in an f150
Black Chrome is bagged, blown and a pleasure to own.

In the 2001's and up? I thought the 97's to 10's were either 4R70 or 4R100. And 11's and up had the new select shift 6's. What was the 5 speed auto? Just curious.
