Good point! However, my question still stands - once in limp mode, what takes the tranny out of it - does it run periodic self-test and drop limp mode if all is good, or it just stays in limp mode till you reset it with a code-scanner tool?
Only way to get it out of limp mode is to disconnect both batteries for a few minutes and the computer resets. It's a real pain in the butt to have to do all the time. If you have a banks transcommand, it might be overriding the Limp program, but in mine, when it is in limp, it BANGS the shifts, and not in a nice way. Can't drive it like that.
well i've already done the lockup mod with the double pole switch. i like it a lot. it doesn't seem to go into limp mode unless it gets to overdrive with out the TC locking up. did it today. if you make sure to remember to lock it its fine.(at least in mine)
In my case, that's exactly what I want to happen. In town, in the "off" position, I want the trans to shift 1,2,3,4 without lockup to engage untill I decide to flip the manual mode.
I guess there are lots of variations in trannies and computers. Mine will go fine for a few days, and then start flashing without warning. Seems to do it in auto mode, or manual mode, but always when I have had the lockup switch to the "off" position for a day or more. This past week, I just left it in the "auto" position, and whenever I wanted it, flipped the manual switch to override it, and so far so good. Worked great!
I had a look at that wiring diagram, and essentially that looks like what I thought I'd have to do to "fool" the computer. I'm just not sure about the value of the resister there, or what the resistance of the Lockup solenoid is and how they compare. Once I figure that out, I'll build something, then I think that should do it.
