94 trooper manually over ride transmission computer

Does anyone have electrical prints or know how to manually over ride the transmission computer. For example are the electrical valves in the transmission 12vdc and can I unplug the transmission computer and jump 12 volts to different electrical valves to see if they will shift the transmission. My transmission will not shift out of 1st without going in to a neutral state and would like to do a more trouble shooting before replacing the transmission. I have a replacement transmission but could change out just the electrical valves if I new that was all that was wrong with it. I did drop the pan in did not find any metal, burnt smells, and the fluid looked good.

thanks

Thanks for the link. I tried a couple times to make it work and it is telling me I would have a better chance downloading if I paid for the preminuim account. Will try again later.

Thanks for your time

Yeah, that site is funny. It may make you wait 45 minutes, trick being you have to stay online with it during that time. Then it will let you download for free. If it is enough in demand, I may try to find a better site and post it myself.
