Hey This Dirtclod and I am at the end of the rope. I had the TPS (APPS) replaced and the mechanic said he drove it and it was fixed. I drove it six blocks and it started messing up again. I took it back and he said to have the computer re-flashed. Or maybe it was the TC lock-up solenoid. What the HELL is going on here?? Someone Help Me!!!!

You had it fixed and it was okay but now it is not? Take it back to the guy that fixed it and have him finish the job. I believe you can adjust the tps.

He said he drove it for about an hour at different speeds and it ran perfect. After I picked up the truck it started to act up. I took it back today and he told he to have the computer re-flahed at the dealership.

Sue him to get your money back for not correcting the problem he charged you for repairing. After all, he said he fixed it.
Then........ carry it somewhere else, let them diagnose it. If they charge you and say they fixed it......well.......you get the picture.
or......... you could tell us EXACTLY what the problem is with the truck. You know, so's we don't have to go pulling up the VERY FEW posts you've made on usenet to figure it out for ourselves.
or........
I'd be glad to guess......like the last dude did.

okay...........
unhook the batteries....... mash the brake pedal.......... clean the terminals........................ clean the posts............................................ hook everything back up........................................ go for a test drive.............................................................
do a repost and post the results.

You replied to my last post so I thought you understood my problem. I don't know what is wrong with it, if I did I wouldn't be on this computer. When the 2000 Dodge 2500 4x4 CTD with 72,212 miles reaches 45-50 mph and shifts to overdrive the torque converter locks up, then unlocks over and over again. At first I thought it was something wrong with the transmission, so I had the fluid and filter changed. Then I took it and after the transmission mechanic diagnosed the problem as the TPS (APPS) he replaced that and the problem still exists. I read that if you cycle the key three times the code will appear on the odometer. I did this and got code P-1693. I cannot find out what this code means. I am just looking for some advice.

Some advice is what you'll get................
but first........
This symptom is EXTREMELY prevelant on Dodge Cummins Diesel trucks.
The FACT of this "In and Out of Lockup" condition is well documented and the repairs addressing the symptom are also well documented.
The APPS sensor that was replaced on your truck is know to produce a "Noisey" signal to the computer. Meaning the signal is not solid enough for the computer to understand what position you have the throttle sitting at.
Their is a "filter" available to condition the signal when it leaves the APPS sensor, in turn making the signal more stable so the computer doesn't have to wonder what the hell is going on. . . Now.........with that in mind........... . There ARE......several major items that cause the symptom, not just the APPS signal, or a bad APPS sensor. . They are................ . There IS a KNOWN problem with the wiring leading away from the generator (aka altenator). Again, it's a problem in causing a "noisy" line that affects signals that the computer recieves. . There IS a known problem with the generator wiring cross feeding a "noisy" signal into the APPS signal wire. . The symptom CAN be caused by the generator itself malfunctioning, not just a noisy signal. . There IS a repair to address the "noisy" generator signal concern. . There IS a known problem with the factory computer programing that effects the transmissions lock-up controll. A "Flash" of the computer to update the logic in it IS available that will effect a change in certain year models of Dodge CD trucks with this symptom. . There IS a known problem with the valve body on these trucks that allows a cross feed of transmission fluid apply pressure to the lockup function. The lockup pressure basically bleeds off, builds up, bleeds off, builds up. Basically. This makes lockup go "in and oput". There is more than one area of the valve body to be concerned with. Govenor pressure circuit is a primary concern. . There IS a replacement valvebody for certain year models of Dodge Cummins Diesel trucks. The replacement unit was NOT intended to address the "in and out of lockup" symptom, but technicians have stated that the symptom went away after installing the updated valve body. . There IS an after market repair kit available for the valve body to address the govenor circuit and others inside the body. . There IS reported success of curing the symptom by replacing the batteries in the truck. (m/o...heresay..pulpfiction..remember i told you to unhook the batteries...?.. I'll explain below) . It is FACT that bad grounds reek havoc on signal lines. . It is insuated, guessed at, hinted to, pulpfictionalized.......that Dodge never intended for this tranny to last in the application it's being used. Dodge knew of the symptoms this particuler transmission exhibits, not only lockup, but also shift concerns..e.t....shift timing, soft shifts, govenor pres. concerns. Dodge has come forward with.....computer flash, valve body, apps signal, generator signal repairs to address this transmission. Dodge, not after market. . It is FACT that a bad convertor will cause this symptom. . It is FACT that this symptom, as well as others concerning the tranny, WILL NEVER SET A FREEK'N CODE !!!!!!!! ( go figure) . It is FACT........that a worn out transmission can't do the job it needs to do, and the only way to find out it's worn out it to do presure checks, "controlled shift" tests with a "shift box", pulling the pan for inspection. . ........... ............
Now to recap to possibilities for your symptom..................
APPS or APPS signal Generator or Generator signal Computer programming (Flash Update available) Valve body Batteries Bad grounds Convertor Transmission
Now......see why I said sue.....if the guy didn't check every single thing on that list above......he fk'n guessed!!!!!!!
Fact, NOT Fiction.
Now....on to the "disconnect battery cable" deal I referred to............
Unhooking the battery cables on this truck....for whatever reason.... WILL...reset computer logic back to the original factory programming and undo all "Learned" adapts that the computer has. And.........you should notice that your symptom has gone away. Untill.........you drive it for a while, and the computer adapts are relearned, then the symptom WILL come back. So, the guy that worked on yer truck basically reset the computer, most likely, and the symptom temporarily disapeared.
Fact, NOT Fiction.
any whooooooooooo..............
that advise I told you I was going to give you, install an aftermarket device that controlls the lockup function of the computer and be done with the whole deal. It fixes it. No guess work. Job done. And....it works great for towing applications.
fact,not fiction.

P1693 is a diagnostic trouble code set in the companion module, which means the PCM has received word from the ECM that it has a problem. In the 2000 Ram w/Cummins, the PCM is Dodge, the ECM is Cummins. You'll have to find a dealer of either Dodge or Cummins to have the ECM DTC's read. I suspect it'll have something to do with the APPS.

Thank You for all of the wonderful information. You spoke of an "aftermarket device that controls the lock up function of the computer". Where can I get this? Who makes it? What is it called? Thank You again

Okay.... first things first. You (or your mechanic) needs to determine whether or not this lock/unlock is "commanded" (ie. called for by the PCM) or not. This is best done with a DRB3, which for the most part, only dealership techs will have. Barring that, back-probe the wire going to pin #7 on the transmission solenoid connector (big round connector - should be an orange/black wire, but verify it's #7). Run the wire up to the cab, and hook to a multi-meter with the other probe on a good ground. When the clutch is unlocked, you should read an open circuit on the meter. When the clutch locks, you should read very little resistance (the PCM switches ground on this wire to activate the TCC LU solenoid).
If the TCC is flapping, and the meter is holding steady, showing a closed circuit, the problem is in the transmission. If the meter shows the fluctuations along with the TCC, then the problem is electrical, and the PCM's reading something that's causing it to beat the TCC into submission.
If it's determined to be an electrical problem, the next step would be to monitor the APPS signal. This can be done with most any OBD-II scan tool that can provide real-time data.

Several companies make them. I'm running the Commander from ATS Diesel (http://www.atsdiesel.com). BD Power (http://www.bd-power.com) makes a product called the TorqLoc, which also does the job.

Does this work or is it a joke. I spoke with someone at BD Power about a torqloc and he said that wasn't the problem. He suggested a noise reducer for the APPS.
