? on torque converter lockout for a E4OD
Guys on my 92 F-150 I have been using some 3157 taillight bulbs and to my surprise the other day they were on with the turn of the key, I guess I never noticed that before. Anyways what I am getting at, is the torque converter lockout tied into the brake light circuit? Here lately my torque converter has been acting funny, like it won't unlock when the brakes are applied or tapped. Just wondering if those LEDs are causing problems. I might have to try and replace them with some standard 3157 automotive bulbs....

I remember reading here a couple of months ago that the E4OD does get a signal from the brake switch so that is probably your problem. The RABS can also be sensitive to brake light problems.
By the way, that just brought up your 1000 posts so congrats.

Just so you guys know, the LED's were causing my problem.... So if your having torque converter problems and you're using LED's in the rear for your taillights and brake lights thats why ;-) I learned the hard way....

Wow, interesting
I'd think it would be ok with resistors wired in though, if you really wanted LEDs
They came on when you turned the key to run?

Yah, heck even my cruise control was affected, because the PCM basically thought the brake was pressed down the whole time the truck was on.... So I fixed my CC and the torque converter locking now ;-) I still had to wire a manually override switch for the torque converter, hated the way it locks to early. Rob's way to much power away from the 5.0 if you know what I mean.....

I had the bright filament of the driver's side 3157 go out in my Bronco the other day and for some reason whenever I used the right blinker the cruise would shut off. I never noticed anything strange with the converter lockup though.

Yah my converter would not lock at all, until I pulled both of the bulbs out physically and replaced them with standard 3157 bulbs, all is well..... ;-) I basically wired up a two way switch that has an LED letting me know that the converter is locked... What I did is find the purple/yellow wire that is coming from the bigger transmission connector and cut that wire and ran each end to the switch's on and off contacts, then grounded the switch for the LED that basically is it.... Just make sure when you get ready to come to a stop that you flip the converter switch off or you will stall the truck and it's very detrimental to the torque converter...

The ECU hasn't thrown the tranny in no fail-safe mode yet and I have been driving it like this for about a year now... Works great with the shift kit I just put in.....
Tgore3 as far as putting it in auto, I haven't really tried to figure that out.....

You can do it with a three-way on/on/off switch. The PCM just grounds the purple/yellow wire so what I did was wire mine so that the top position is auto, the middle position is unlocked, and the down position is locked. It's pretty easy to figure out once you look at the switch.
