I have a 2009 Chevrolet Trailblazer LT 4.2l L6 4x4 with 4L60-E transmission. Built in Canada. Every time I accelerate my stabilitrak on light comes on and goes away. Once before I had service stabilitrak, traction on, Engine reduced power lights and I could not accelerate like normal. I couldn't go over 20mph. I took apart the throttle body, cleaned her, replaced intake manifold gaskets, shop said I needed both rear wheel sensors. I got them replaced and it still happens. This time they said it was the steering position sensor in the steering column. My question is, WHICH PART NUMBER DO I NEED???? There are two OE numbers I keep pulling up and I don't want to accidentally get the wrong one and have to attempt to send it back with this Virus going around, we're going to have snail mail with alot of workers sick. Please let me know if I'm supposed to get part number 19150081 or 26104070.
