For the first time really trying out the mystery switch near my house, I locked up the converter and it worked fine for a few miles. It unlocked and locked with control of the switch. Then the last time I unlocked it as I approached a red light... It didn't unlock! I turned right at the light nearly stalling my truck (didn't make a complete stop). I heard some drivetrain chatter as the rpm's went below 600. The switch is wired correctly and there is no discontinuity. I finally dropped it in N and coasted to a stop. Then I dropped it in D again (while stopped) and the truck stalled. I restarted it and drove home in 1st, luckily I was in my neighborhood area.

Has this ever happened to anyone else? The switch is wired correctly, could it have to do with the build date of my truck?

Could I ruin anything by nearly stalling and actually stalling the truck like that while in D?

 

You either have a bad lock up solenoid or a short to ground on that circuit. I would check the switch you installed first. Not all switches are created equal and they do fail a lot. I installed mine with a quick disconnect at the splice in the harness. I used one from a early single wire oxygen sensor. Now if it fails like yours has I can unplug the connector and I will know right off if it is my circuit or something else.

 

Thanks for the reply. Switch seems ok. The problem started right after I shorted the relay terminals in the fuse box under the hood and took it for a test drive. My truck was built in Oct. 1995. Exactly during the period that TST says the lock up switch might not work. But I don't know...

Anyway, I went ahead and unplugged it for now. I'll find another use for the switch in my dash, I'd rather not burn up my tranny.

 

Yup, sounds like you need a reflash.

 

part number for the reflash is 04886926

wcbcruzer thats the part number you can give to Dodge for the flash,, as some Dodge shops cant find it or say there isnt one available,, and yes Oct 95 NEEDS the flash to work properly

 

My truck is in the same dillema. Please let us know how much $$ and or time they charge for it.

Outlaw, thanks for the flash #.

 

When they flashed mine, I think the charge was 1 hour labor, as before they can flash it, they have to make sure there is no codes present.

 

Thanks Outlaw. I'll see what the dealer says. Is there any other benefits from re-flashing?

 

they reflashed mine for $75 it worked great for the lockup but now i get some code's thrown that dosen't pertain to my year truck no big deal though
