Bmod,
I've read through many threads here about problems with shifts and especially my problem with no O/D until 200 degrees problem which I still haven't figured out but it sounds to me that your B solenoid (2-3) is sticking/defective. I've been told that you should have a reading of 20-40 ohms across this solenoid but I don't have a pinout as of yet. My problem I have determined so far is definately temperature related but as we all know warm oil flows better than cold oil so your valve hanging on the 2-3 until it gets a little warm sounds probable. Located in valve body viewable when pan is removed. 87 is a high ratio code relating to the 2-3. i am not sure about the 85, maybe the transmission goohoos can help out you and me. Mike L. or GMCTD please respond to us, please.
