I put a ground on my od switch and wallaa overdrive is there.but overdrive is immed after 3rd gear and doesnt really downshift good now.is there a way to make it work properly without having to put a switch on the dash.I read something about a pressure switch in the governor port anybody hear of that?I am excited even though it's not working the way it was designed
I do still have tps shorted or open and od switch shorted or open???

What I would do is rig up a test light to the flue wire and go for a ride. Make sure that wire is powered all the time. I;ve had a couple guys have a short and when they hit a bump the light/pwr would go out which would kick the o.d out. Once you are certain you have pwr all the time, the next step is to manually ground out the front wire and make sure it holds when you have it engaged for any length of time untill you disengage the switch. If that checks out, a proper working tps or Pot setup should work. If it does not, I would check the wiring heading down to the trans and verify the pcm is working right. Any questions give me a call

Similar Problems
My laundry list includes:
OD cuts out, Alternator function reduces or quits and speedo goes out. Is this too a PCM issue (ya think?)
I also have other issues stemming from neglect/botched electrical repair that may be contributing. Hard to say, but let's assume the first item is all from the same problem source....

Hey guys I have a problem or a question that falls into this category. I seem to have no time to research this but my OD works after the trans is warmed up but it seems like the speedo has to say I am doin between 55 and 60 before it will kick in. At first I thought that it was an issue with the trans but when it goes into OD it takes off like a shot and is solid as hell. My question is I know on a gas there is an adjustable cable for the kickdown that would affect this. I should also mention if I put any more than half throttle even gently it will not hold OD til I hit 60 on the speedo. Also will mention speedo is 12 mph off so 60 is actually bout 72. this means OD is not engaging until around 68. Any ideas? sorry this was so long!
