Trans troubles

[vaughn]

04 trailblazer. Mother in laws. Didn't. Change fluid so it quit pulling. Pulled pan no metal so changed filter and all fluid. Ran great for a month now has 1st and 2nd. But no top. Won't change. Any ideas. Out of my skillet to fix and she is on fixed income

What's the mileage? I know it's weird, but some lucky folks get 300,000 on the original, while another may not make the 1st hundred.

150,000 miles is the average on a 4l60e. did you possibly break the shift solenoid when you put the pan back on. it's not uncommon to break it as tight as the pan and crossmember are together.
