My friend said it helped his transmission hang on a little bit longer so i wanted to try it.Hopefully it'll last long enough till i can save enough to buy a transmission.

i want to get rid of my converter lock-up. i hate that thing, all it does it cut the power in half and hurts my gas mileage. It comes on too soon and instead of kicking off, it waits until it needs to shift down (where unlocking and giving back the 400-800 rpms would do the trick), im calling different shops looking for someone that can possible reprogram the computer or maybe just disconnecting the thing, not sure yet

ya i was thinking 410:1 gears, i know about the heat thing, and it hurts the fuel mileage up here, always searching for the right rpms, up hill, and down hill, and back up, not major hills, just enough to get anoying, and drive is alittle low for my 70mph on the interstate, i do have to fix the intake still so im hoping that will help alot, then a computer tune to straighten out the air fuel mix, and then the gears, bye bye problems, i hope

why would you want to turn it on with a switch, the truck decides the best time to turn it on, and it only changes by a couple hundred RPM at most, if you dont let off the gas when you turn it on, it makes the truck buck really hard for a second and if you forget to turn it off when you come to a light, the truck will stall. all you need is a wire powered on with the ignition that goes to a switch that goes to the plug on the trans, you have a 2 wire plug, one is for the overdrive and the other is for the lockup, but i'm not sure which is which, I have a single wire on a 3 speed, my repair manual doesn't give the color codes for those two wires.

I must be thinking of a different setup, but I found a site that might help, https://dodgeforum.com/forum/2nd-gen...ckup-46re.html

Lock up is almost unnoticeable. At moderate throttle the truck will shift 1-2-3-lockup-4. When you press the o/d cancellation button the transmission will shift 1-2-3-lockup.
DONT DISABLE LOCKUP, it will cause problems. If you dont like the transmission hunting for gears then just hit the o/d cancellation button, it makes around town driving much more enjoyable.

I don't know if this mod is good or bad.
But in an effort to help protect some problems I see I drew up a schematic based on the link below.
It should keep the trans from staying locked up when coming to a stop.
I think the reason the diesel guys use it is to let the engine slow the truck down kind of like a manual transmission.
I believe someone else said that earlier in the post.
If you use that setup and get one of these -

You can put the module in to protect a lot of the concerns about killing the motor when coming to a stop.
Something like this -

I am not responsible for any misinformation from this schematic.
Use at your own risk!
I have not tried this but this whole post has got me thinking about trying it to see if it works.
Just to see if it is a viable option.
Edit:
Estimated Parts cost
$50 RPM Activated Switch http://www.summitracing.com/parts/SUM-830450/
$8.5 275-218 relay http://www.radioshack.com/product/in...ductId=2049722
$5 Safety covered toggle switch http://www.radioshack.com/product/in...rName=Category
Total Estimated Cost
$63.5

Here's another that's a little different, but supposed to work if you encounter a check engine light:
