97 Blazer shifting

[troyky29]

I have a 97 Blazer auto transmission, with the 4.3. I am trying to get an idea of the problem before I send it to the shop. When driving after it has been sitting, the transmssion shifts thru all the gears fine. After driving a couple miles, I lose 1st gear and overdrive. 2nd and 3rd work fine. It takes off in 2nd gear and then 3rd thats it. It can sit a couple hours and shift fine for a couple miles, then back to just 2nd and 3rd. I would'nt think that this is transmission failure, maybe something electrical? Any input would be great! Almost forgot, trans was rebuilt about 10,000 miles ago.

If it is going to the shop let them figure it out.
That is what you will be paying them for.
Needs put on a transmission/engine capable scanner andf check things out.
If any codes transmission or engine post back code

Just wanting to know if anybody has ran across this problem before. If it is something simple, maybe I can avoid shop costs. I am sure I am not the first person to encounter this problem. Even if I do take it to the shop, I would like to get a rough idea to what the problem is.

You will have to get it on a transmission/engine capable scanner to see what is going on.
Check for codes and shift adpative data and slippage and check shift solenoids.

Took to Oreilley Auto and ran the codes. Came back as Transmssion shift solenoid malfunction. Hopefully this solves the problem.

That does not say much.
You need to get it on a transmission capable scanner and find out which one a why.
And do not forget the 97 is a bad year for ign switches that can cause that problem.
Take it back and let the shop check it out.
