fordboy these guys are just trying to help you out. They dont want to see you burn up a good tranny. E4ods are an expensive animal to get rebuilt so you could use that money on someting good.

What is the right reason to lock the torque converter? Shoot, these trucks smoke enough without trying most of the time, no need to make more. I'm guessing the lockup might be for less friction close to WOT or the reason the C6 always have horrible fuel economy.

Personally, I had an issue with mine not grounding properly and the switch gives me the ability operate it manually. It sucked running down the road with the RPMs all over the place because of the TC......

If you have $2000 in the bank and nothing to spend it on than sure, go ahead and try it. Because thats what it will cost you to replace that transmission. Air pollution aside, why would you want to make that kind of smoke? diesel isn't getting any cheaper and smoke is wasted fuel. From what I hear you can also make smoke by setting paper money on fire.
It may wreck the tranny and then maybe not, because if you really lug the engine it won't be putting out that much torque anyway, but think about what you're doing to your poor truck. If you try and haul up a hill and the transmission slips without you realizing it, you will kill it no matter how well built the tranny is. They will get hot enough from slipping to melt steel.

When I see somebody's diesel smoking like a chimney, I am half tempted to report them to the smog nazis. What is so great about choking me with your unburnt fuel? I must have missed something in class on how to be like a 15 year old.
I know ......... put a burning tire down that 8 inch stack........that'll make more smoke without killing your tranny.
Just yank'n your chain.
Seriously, this is not a good idea as many have suggested above. But, you have the info. to do it if you must.

My 02 Excursion has bipolar disorder, especially when towing. Under 45 MPG with the torque converter unlocked, it can't get out of its own way. Reminds me of all those bad dreams I had as a kid with the evil vulture trying to get me, and concrete blocks around my feet. Once it's locked up, and doing about 65, it passes everything on the hill. I've been so ticked off at it's sloth like attitude, I've floored it and tried to kill it! Yes, I feel bad about that. It actually seems faster to just sit still. God I wish it was a manual. 
I've considered doing the TQ lockup mod many times. However, Ford seems to have designed it to take care of itself, and not give a rip about who is driving it. I don't want to spend any money on it, so I just let it be.

The only reason I used to do that is to get rid of someone following so close I barely see their roof over the tailgate - I had one ******* pull into a gas station with me and have the balls to yell at me for smoking him, told him if he wasn't drafting he wouldn't be smelling it
Those guys really used to **** me off, especially if there are more than one road lanes open and they still run like their bumper is welded to mine... Then I installed one of those 3-ball draw-bars made of solid 2x2" steel piece, and turned the pump down, and when needed just give 'em tailgaters the engine braking treatment 
Oh, and did I mention how much I love having 20+ mpg at 65 mph?

Heh, when somebody is drafting me, I put the right turn signal on, and slow down at every road.The only reason I used to do that is to get rid of someone following so close I barely see their roof over the tailgate - I had one ******* pull into a gas station with me and have the balls to yell at me for smoking him, told him if he wasn't drafting he wouldn't be smelling it

you gotta keep these choker motors wound up if you want to be in the powerband. All my company rides are choker trucks except for the IH4700 which is a DT466. I am firmly convinced that they are intentionally programed to be slugs for longevity reasons as well as fuel economy. Even the bolt-action '97 f450 is sluglike in it's performance. Only the '05 f550 has something that resembles acceleration but it can't stay out of the shop. right now it's in week 2 of being over at MVFT for yet another replacement turbo. and lo and behold....it's just 500miles outside of it's 100k warranty. They should be glad I'm not the owner of the chassis, it'd be on fire on their front lot

I just rtan the wire fron the lockup switch to a fuse then to the ground.My setup is run from the computer to the switch to ground.It servs to only lock up the convertor when I want it to I don,t see the need to unlock the convertor by a manual method.I lock it up when ZI shift into lock up-leav it alone til I plan to stop then at 35 MPH flip the switch.The convertor will not build anywhere near as much heat in lock up as it can when unlocked.
It has proved to be the best mod i ever did.
