How to replace shift solenoid in 1999 Chevy Blazer - Fix OBD P0758 on 4L60-E GM Transmission

In this video, master mechanic Mike Bauer and myself show you how to replace shift solenoid B (or as GM likes to call it, shift solenoid 2-3). The Service Engine Soon (SES) light came on and the car was stuck in 3rd gear when putting the automatic transmission into Drive.

My $40 OBD II diagnostic tool read the error code from the car as P0758 and a quick Google search showed many other GM owners that have the 4L60-E transmission having the same problem, requiring the same fix and being told it will cost thousands of dollars to repair 'properly' by 'professional' mechanics.

The dealer recommended tearing down the entire transmission first to see if it was worth repairing at a cost of $330. The dealer also recommended changing all 5 shift solenoids and the wiring harness, plus a new filter and fluid at a cost of $1100.

This repair required about 90 minutes and $65 worth of parts doing it ourselves.

The car has 192k miles on it. I'm the original owner and always kept up with the maintenance. It is the original transmission and this is the first repair the transmission has required in since I purchased the car in 1999 (16 years ago). And, after the repair, it's still working great!

Before starting this project, two fantastic videos showed me exactly what to expect if I was going to tackle the job myself.

The first video is by a gentleman named Craig Lambaria: https://www.youtube.com/watch?v=dkLQpezVk9I

The second video is by Silas Miller: https://www.youtube.com/watch?v=OGckmJK2rNQ

My goal was to make a complete 'start to finish' video with as few edits as possible so anyone with a couple of tools and little to no experience could follow along and complete the repair on their own.

WARNING: Work on the car when the engine is cold. The transmission fluid can be very hot after driving the car and it can seriously burn and injure you!
