transmission

[nusch]

I have a 94 5.7L blazer and it has no power. It starts out in third and won't shift out of it. Reverse works fine. No codes have come on but I am going to check them and make sure. I read in another post that the ecm sets it in third when there is a problem. It came on gradually and would only do this when it warmed up. Now it does it when it is hot or cold. I am going to check out the VSS even though there is no problem with my speedometer. Does anyone know what would do this?

Now that I realized that the code can set wothout turning the service engine soon light on I pulled the codes off and found that code 81 was set. How do I go by fixing the 2-3 shift solenoid?

I got under the truck today and tried to find the yellow/black wire that is supposed to go to the 2-3 shift solenoid but could only find the same color that goes to the temp sensor. Does anyone know where the solenoid would be on the transmission?

your best bet would be to get on ebay or something and buy a pamphlet on rebuilding it. they are pretty cheap and will tell you where your solenoid is.....

Those solenoids are inside the pan attached to the valve body.. There is a rather large harness going to the tranny, the wire is in it. If you drop the tranny pan you will see the solenoids on the sides of the valve body. I think they can be changed without removing the valve body. You will see the wire colors going to the solenoids inside. I think those solenoids cost about $50+ each.
