Ok...that does actually make some sense. There is amore accurate way to adjust the APPS (aka TPS). I will post it if/when I can find it.

 

ok. Heres the info:

https://www.dieselbombers.com/24-val...ting-apps.html

Instructions for adjusting the APPS (TPS):

Tools: Digital Volt Meter, T-20 Torx bit, #1 phillips, 10mm socket

With the key on, engine off you need to probe the APPS wire to see where the voltage is currently set at.
The best location to probe the wire is on the PCM (Power Control Module) which is located on the passenger firewall behind the air intake.
You want the C1 connector, this is the connector closest to the engine
You want the orange wire with a dark blue tracer which is pin #23
Voltage should be somewhere around 0.5 volts,
At this point the voltage reading does not matter, it just has to be accurately written down for later reference
TURN THE IGNITION OFF ON THE TRUCK

Remove the black plastic cover off of your APPS. There are two plastic screws. One on the top and one on the front facing the radiator. It takes a little prying to pull it off.

Undo the 6-10mm bolts that hold the bracketru in place but DO NOT REMOVE THE CABLES!!

You will notice the APPS is on the back of the bracketry that you just removed, it is held in place by 2-T20 torx bit screws. These screws have a little bit of locktite on them so make sure you have a good socket and gently give a little tap with a hammer before attempting to loosen. Be very careful because these screws strip VERY easily and you only get one shot at them (VERY VERY VERY IMPORTANT; They are VERY tight).

On the APPS you will find a white tag that gives you the information on what the APPS voltage should be.
After loosening the screws (do not remove) you can rotate the APPS clockwise or counter clockwise to get the adjustment (towards the front of the truck increases voltage and towards the rear of the truck decreases voltage)
The reading you took at the beginning of the process on pin #23 should match the white tag on your APPS. If it doesn't the adjust accordingly.







Try that and see what happens.



Thanks for posting Luke !

 

Okay, I don't know where 80-100 km per hour translates to American mph, but if it is around 38 to 40 mph I will bet it is going in and out of lock up. That is a very typical thing for the 2nd gen 24 valves to do. It should go away either above or below that speed, and there are guys that have fought it for years. If you try all the apps mods with no fix, you can buy a Commander from ATS and that will take care of the problem when you set it to keep the Torque Converter locked below 35 mph. I have been running it for years and the only time I get the "shuttle shift" as we call it is when I dial it up about 45mph.
Good luck.

 

5/8 of a mile in a kilometer that would make it 50-65 mph

 

Ok, well that doesn't fit the symptom. Nevermind.

 

ok thanks

 

Did you get this resolved?

 

HASNT ACTED UP AND I HAVE HEARD FROM MORE THAN A FEW PEOPLE ABOUT THE COMMANDER FROM ATS SO WILL TRY THAT,THANKS TO EVERYONE
