Sounds like something broke in the torque converter. I would call a transmission shop like AAA Transmission. If they have anyone that really knows transmission they will be able to tell you for sure.

You are asking about the lift pump or booster pump. The relay for this pump is located behind the doghouse. Lift the doghouse away and look at the side panel closest to the driver's seat. You will see the relay bolted to it. Treat this part with care. This relay is discontinued and I did not find a usable superseded part number. GM Part # 15528707. Good luck.

Did you happen to find small pieces of plastic in the driver's floorboard? If so you unwittingly found the problem. The brake light switch is mounted so its plunger presses against a small plastic insert. The insert is pushed into a hole in the break pedal arm. When the brake is not depressed it rests the the upmost position so when the insert (when intact and unbroken) does the pushing up against the brake light switch plunger. Check the condition of the insert in the brake pedal arm and replace if necessary.

Reprogramming involves taking the following steps, but there may be car-model-related variations so only do the job for real with the specific EcuTek instruction manual alongside you.
  1. Connect the vehicle interface cable to the OBD-II connector and turn the ignition switch to ON
  2. Open the ProECU software and choose Tools then Detect Vehicle
  3. Select Program Engine ECU
  4. Choose Query ECU to identify the ECU version fitted to the car
  5. Select Choose ROM File and pick the relevant modified ROM file to program into the ECU
  6. Enter the ROM filename or your unique name for the ROM file in the Comments box so that in future you know exactly which ROM is in the ECU
  7. Ensure that all electrical consumers about the car (such as interior lights, heater blower, stereo etc.) are turned OFF and that mobile phones are kept away from the car
  8. Choose Program ECU
  9. After programming the ECU, follow the on-screen instruction to cycle the Ignition
  10. Start the engine

You've taken care of some really good things to check. A sensor would be my bet too. However, you could be dealing with a set of loose connectors, most likely a wiring harness when they changed out your transmission; I'd look where the engine-transmission join, or anyplace they would have had to disconnect wires to get to the transmission. They could have been loosely connected, and have come further apart. Perhaps if you find some loose connections, zip tie it or rubber band it together if the connector is cracked or broken.

Suspect wheel speed sensor. Likely the shudder is traction control activating from false reading of wheel sensor.

Have ODB codes read, it may identify which wheel.

it should clear the computer in like 5 seconds, but if the codes havent been serviced or parts replaced the CEL will come back on eventually. Usually within 10 mins

Would you please write back and elaborate on why your Astro won't stay running? Have you looked under the hood for faulty wiring at the battery or around the engine? Sometimes by looking around you can stumble across defects. Have you tested any systems? I would like to get an idea of what type of advice you are looking for. If you could give me an idea of what you have for tool and experience. I think I could help you better. Has the van had any recent work performed? After the engine is started. How long will the engine run before it stalls? Will it run long enough to reach running temperature? after the engine starts. How does the engine run? Is the idle and acceleration normal? Is the engine light on? Is the security light on?

Heaven only knows.
Check fluids. If low, where did it all go? Broken Hose?
If fluids are all fine, going to take surgery but your description sounds like torque converter failure.
Surgery is in your future..

What do you mean , tries to start ? When you turn the key to start what happens ? Starter clicks , starter spins the engine around . Doesn't start an run . ,what ? Now it just so happens that your vehicle does not have a relay switch . Does the car have automatic trans . or manual ? Power from the ignition switch goes through the park neutral position switch to the starter solenoid S terminal for auto trans , An through the clutch pedal position switch for a manual trans .

Your best bet , have a qualified repair shop check it out .

Your battery is dead. Why it is dead is another investigation. Is it getting charged? If not the alternator could be gone.
Charge the battery, or if it is 6+ years old, replace the battery, charge, and then test.
If it runs ok with a charged battery, but the battery keeps running down, then it is likely the alternator or something in the charging circuit.

OK, now we know you have checked the battery. The door locks not opening and the relay failing to pull up means they are not getting enough juice. So if it's not the battery, then its something else in the electrical system. Because two completely separate systems (locks, starter/relay) are affected, it is something common to both of them. But go ahead and check the fuses anyway. Also check all electrical connections (Battery and other) for corrosion or looseness

Could just be a loose spark plug wire. Depending on how long it's been sitting animals tend to hide under the hood may have knocked it loose. Drive it to orileys or autozone and they can scan your computer if you have a check engine light on which in my experience with a misfire it sets off the check engine light or your gas could be old also.
