As far as drivability, the thing really hammers the gears between 1st and 2nd.
I'm worried that this is way to harsh on the truck's other drive train components. The shift between 2nd and 3rd is quite a bit softer, but way more firmer than stock.

I'm almost inclined to put the stock unit back in unless somebody can tell me that the harsh shift between 1-2 is ok for my truck.

Reminder of what I have:
2001 F150 Supercrew with 5.4L
35" tires
4.56 gears
5 psi intercooled blower.

Thanks
