Tranny solenoid
Does anyone have a diagram or specific part number for the solenoids for a 2000 blazer. Specifically the lock up 1-2 solenoid? Auto zone and other stores have two options, and for the life of me, I can't figure out for sure which one goes where. I don't want to spend $30 some dollars to have the wrong part. Also, anyone know what they are supposed to ohm out at? The 4 "corners" tested out at 20, 20, 20, and 9. From what info I can find, this might be normal?

What is a "lock up 1-2 solenoid? The 4L60E transmission has two identical shift solenoids at the rear, sometimes called the A and B solenoid, or 1-2 and 3-4 solenoids. There is a Pressure Control Solenoid just forward of that on the side of the valve body. Up front you have the lockup on-off solenoid mounted into the bottom of the pump with two small bolts, and two similar looking solenoids mounted in the front of the valve body. One is the pressure control for the lockup, or Lockup PWM solenoid, and the other is the 3-2 downshift solenoid.
