I've searched to find out if anyone makes a computer controlled lockout for 1st gear. Took my 93 FZJ80 on its first trip and noticed that when your in 4low, 1st gear(tranny selection).. the damn thing wants to fly into 2nd. This really irritates me when engine breaking on a steep hill cause i hate riding my damn brakes the whole time(im so used to a manual). The only thing i could find in the search was a company that actually goes inside the guts of the tranny. In the Jeep Cherokees they have a lockout where you tell the computer to lockout 1st and not let it shift. Anything out there for this fix? So irritating. Any help would be appreciated.
