I have an 03 s-10 with the v6 and i had the service engine light checked out and i was told it was the shift solenoid b that was bad. Just recently i have changed the transmission solenoid and both the a and b solenoid. When i started the truck i now have no dash, my rpm, mph, fuel, and temp gauge all do not work now, also the indicator that shows when you are in drive and in park all does not work either. but my alt gauge still works. is there something I missed when changing all three solenoids? i have checked the fuses and they are all good. i made sure everything was clipped in that i unhooked. do i need to reset my computer? also when it is put in gear it shifts harder now? please help, any ideas? thanks

The transmission is controlled by the Transmission Control Unit (TCU).
Throttle
position, rpm, and speed are input parameters to the TCU. The TCU has a
default set of shift patterns. These shift patterns change over time
based on your specific vehicle setup and driving habbits.
The
shift patterns are only slightly affected by driving habbits over many
driving cycles. But, changing the relationship between the throttle
position and the actual speed being reported by the speed sensor can
have an immediate effect on shift patterns.
While your speedo
may now be correct, the realtionship between rpm and thottle position
has not been corrected. That would take a gear change in the
differentials.
The TCU can be reset to an inital learn base line. When this is done, the TCU will instantly learn the dynamics of your setup.
Any shop with an advanced ODB scan tool can reset the the TCU. The dealer or a transmission shop would be preferable.
You really should change your differential gears as opposed to resetting the TCU

try autozone.com to see if they have your car listed for diagrams pictures and step by step instructions if your car is not listed then try your local library they have all the car manuals and even copy them for you

the dealer is right it sounds like the solinoid is either jaming in the body or has an intermitant fault in the solinoid

You will have to change the solenoids no quick fix its kind of a pain to change them and a very common problem

unplug trans and see if it still does this if so short in wires if not bad solenoid.
