the car needs to be reset with the reset button located in the engine conpartment.hope this helps?

The EMC detected and problem so it's in limp mode, As long as it's in limp mode the 4th and OD will not activate. Take care not to burn up the transmission by running it hard while your in the limp mode.
Your going to have to get the truck scanned to clear any codes and why there are DTC codes. Auto Zone scan for free and most auto shops charge $10.00 to $20.00 to scan sine they want the business.
If you want to clear the codes your self you can put the ignition to the run position and pull the ECM (Batt) fuse out for 20 sec and place it back in then start the truck. It may stall but let it, just start it again and this would have cleared all the DTC code history.
The transmission should be running fine unless there is a problem and the service engine light will be on again and you'll be in limp mode still with an updated DTC in the ECM.
Good luck and hope this helps.

Check the TPS Sensor for open spotsThe fuel pump may be going also & binds upthus no fuel

sounds like it is . try doing it in neutral than putting it in gear in driving if that works than the switch is bad.

the relay or and a broken wire or corrided wire.

Sounds like you think there is a magic genie out there,that doesn't have to look at a wiring diagram or test anythingYou have to understand any system or component your aboutto work on or test FIRSTI suggest if your working on this yourself, you Google the question & also go to You Tube Video, it is all there except maybe where to start your testing

I wash mine with a pressure washer, then scrub it with a bucket of soapy water and an automotive type brush, then wash again.

bad power wires

I had the same problem with my 96 Chevy 4.3. It idled rough enough to shake the truck at a stop. It revved up fine but sputtered on take off. My truck did not want to stay in overdrive because of the low rev. I changed cap, rotor, plugs, wires and this did nothing. Finally I took the intake off and found corrosion on the side intake gaskets near the rear of the engine causing a vacuum leak.

Fuse?

your oxygen sensors locations.one oxygen sensor located in the exhaust pipe before catalytic converter.the other oxygen sensor located in the exhaust pipe after the catalytic converter.

check for a short it could be anywhere in the line

Since you didn't state whether it is a V6 or V8, I'll give you both.

V6 -4.3Liter
Firing Order is 1-6-5-4-3-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap, faces the front of the engine.

->Drivers side, spark plug order in engine, starting from the Front going back:
1-3-5
->Passenger side, spark plug order in engine,
starting from the Front going back:
2-4-6

If it's Electronic, the distributor cap has a Left side, (Drivers side), and a Right side, (Passenger side)
Starting from the Front, going back on the Left side,
3-1-5
Starting from the Front going back on the Right side,
2-4-6

V8-5.0, 5.7, and 7.4Liter
Firing Order is 1-8-4-3-6-5-7-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap,
faces Front, towards the Drivers side.

Electronic distributor cap has two sides. Drivers, (Left), side and Passenger, (Right), side.
Starting from Front going back on Drivers side,
1-7-3-5

check crank position sensor. check cam position sensor. Have the fault codes read for fault. Check key battery is not flat causing the immobiliser not to work.

timing. pass side under dash brnor tan with black stripe wire, one connector,disconnect it. check engine light will come on. set your timing, reconnect wire. disconnect battery to clear check engine light.

Are you sure you are on number 1 spark plug wire? if so your wires must be off on the cap. put the engine on top dead center on the compression stroke, that is with number 1 spark plug removed turn the motor over until you feel air rushing out of that plug hole and the timing marks line up at TDC. Then make sure that the rotor on the distributor is pointing at the number 1 plug wire, if not you will need to re-time the wires on the cap to where you make number 1 were the rotor is pointing and work clockwise around from there 1,8,4,3,6,5,7,2.
