Can I down load the codes from my 2001 chevy astro?

It could be one of two things. Either a loose/faulty speed sensor on one of the wheels or the ABS module itself. I would check/clean the connectors for the speed sensors first and if that doesnt work then head to a wrecking yard and grab a "new" ABS module.

Thats a shift solenoid code... 1-2 shift problem. Bad solenoid, or ??? Have to diagnose it.

hammer and punch

you need to call your local dealer and tell them the VIN number.
they will be able to tell you the part number for the sliding door roller.
there are upper, lower and side rollers

the theftlock has engaged, try removing it and see if the code is written on the radio, if not try your dealer, especially if they supplied it new, or ring the supply dealer from the handbook, you have to have the code.

Reset the ECU / PCM for Check Engine light removing the neg battery cable for 5 minutes to reset the codes. If the warnin glight come on again, I suggest scanning you vehicle for details, one fault is in there.

Good luck (remember rated this help).

if you call a chevy dealership with your VIN number they should be able to tell you.

pull off the center console inside the van to expose the engine. the distributor will be right in front of you. remove 2 screws from the cap, and make sure you get the wires on in the exact order you remove them, or else it wont start. rotor is underneath cap, and i believe the coil is right there on the cap.

The Shift solenoids are located in the transmission oil pan. I would recommend replacing both shift solenoids while you're in there. Also replace the filter and pan gasket. The shift solenoids are located towards the rear of the valvebody and will be identical to each other. They are held in place by a retaining clip which is easily removed with a small screwdriver or similar tool. Care must be taken as parts may fly out of the bore when the solenoids are removed. Hope this helps.

It is located where the big hose comming out of your radiator connects to top of engine. Remove hose from engine your thermostat is undernieth
