I have HP Tuner on my 2005 8.1l/4L80E (that is really in a 75 GMC C35). Using HP Tuner I can send a command via my laptop to make the thing stay in first gear while I'm descending the mountain with a 22' GN on it. Pretty handy since I'm using a stock 3 speed column shift and cannot hit 1st gear with the shifter (yes I've done all the mods to the shifter and the mount). Not good cause I have to use my laptop to shift it.
Anyone know if there is a wireless/blue tooth option out there that I can use to command shift a 4L80E via an app on my phone?
Edit: all I'm doing is going down a 6 mile very steep dirt road and want to shift it manually to D, then use my phone to make it stay in 1st gear. I can do this via laptop already and it's pretty handy, but inconvenient.
