#355 of 382 Cylinder Lock Removal by dgcaller

It's been a while since I've done this. As recall, you have to remove a small solenoid that mounts underneath the key cylinder. I think you can also just pull the shaft in the center of the solenoid downward to unock the wheel instead of removing the solenoid. I'll check my service manuals and get back to you in a day or so.

Hi! I recently purchased a 1996 Chevy Blazer 4 by 4. When driving, the "Check Engine" light comes on and I noticed my transmission slipping. My car has to reach a couple thousand to three thousand RPM's to finally start moving. Just by happenstance, my battery died on the car. When I jumped it, my check engine light was off and my car shifted and drove fine. After about 10 minutes of driving, the "Check Engine" light came backon and the transmission started slipping again. Thoughts? Thanks!!!

While attempting to remove the cylinder lock, I barely moved the steering wheel and it locked. And the cylinder lock will not turn forward or backwards. What could be the problem? What is the solution to solving this problem?

I am having similar troubles with my Blazer. I haven't done any work to it, but I was driving and it was like it jumped out of 3rd into 1st at about 60mph. I checked my fluid and it was fine, and have drove it a couple times since. Someone told me that it may be a sensor or solenoid that might have went out that controls the shifting in the tranny, is this possible?

I was driving down the road about 50 mph. & suddenly the trans.acted like it was in neutral
i coasted over to the side & i didn't have any gears at all, no foreward or reverse gears!
I know it isnt the transfer case because when you put it to drive, you would hear noise from it,
no unusual noises no matter which gear you put it in?
Could this be the front pump going out, or possibly the torque converter,
It was real strange, it went from fine to no gears at all just like that! thanks Would appreciate
any input on this. Mike!

There are several input sensors that feed the computer, which controls a set of solenoids in the valve body. They are what actually do the shifting, along with the shift lever. All those solenoids require electricity, of course, and if the power gets interrupted by a bad contact in the key switch (where the power comes from) all sorts of weird things can happen. Having only 2nd and 4th gears, for example, or stuck in 4th when the shift lever is in Drive. But you can have bad solenoids too, especially the high pressure solenoid. There are some bugs in the original wiring harness in the valve body, and Chevy has a replacement harness that has two solenoids hard wired to it. But don't go replacing anything yet. Did the service engine soon light come on when you had this trouble? If so, take the car to a diagnostic place and have them check the DTCs (diagnostic trouble codes). They tell you exactly what it wrong. UM, well. most of the time. When my key switch went out, I got DTCs saying two of the solenoids were bad, but it turned out that they were just not getting power from the key switch.
Hope this helps.
Diane

Sounds a bit like my trouble. Can you remember if your speedometer keeps working? In my case, it was the speedo sensor.

I got the same car. I understand what your talking about when u say the "First Ten". My car has the same issue where it only shifts just right in those first mins at the first start of the day. Get someone to check your codes. Mine was my 3-2 Shift Solenoid. I went to AdvanceAuto and got the part for like 30 something. The Solenoid just melts out in these type of trans. Just gotta drop the pan and unplug then replace. Very simple if you dont mind getting a bit messy. Good luck fellow blazer
