Check the wiring for a short circuit. If the solenoids are good, its either not getting the command, or the signal isn't making it to the solenoids.

Does anyone know if it could be the torqu converter or the valve body? trans shifts good through all gears only no lock up.

You would have to do pressure testing to determine if the VB was operating correctly, and electrical testing to check the solenoids. I don't know off the top of my head what wires are for what, but there is a wiring diagram in the FSM. There is a link to a FSM in the archives here, need only do a search.

Apparently the link is gone. Chrysler is a bit overkill on keeping all materials regarding the products it makes under wraps unless you buy it. What year is your truck?

Sorry, now I see it on your first post. Drop me a PM.

Ok so i was reading some other posts and saw somthing about a manual lock up switch. I read some info on it and decided to give it a try. Got it all in and while driving about 35-40 mph flip the switch and you can feel a slight drop in rpm but if i throttle up it fells like it releases,any ideas?

did the factory offer a lock-up converter "upgrade"

I just got my 2006 2500 it was perchased at auction with 35,000 miles on it
I wanted to know how the truck came as stock
And a Dealer did a Vin# report for me
it shows in the list that it came with a 4.10 axel ratio 11.5 rear end
4-speed 48RE transmission / All 4-speed Automatic trans.
Lock-Up Torque Converter.
?Is that an Upgrade ? -Or just how all of them come?
