I have searched the threads and come to the conclusion that my solenoids for torque converter lockup and my 3/4 shifter might not be getting the 12 volts required to run properly since the computer is the ground side of the connection, ( i also had alot of other non essential wiring go bad, the radio went out, the interior lights, the blower motor for the heater ) Anyways im wondering if this loss of power could of also caused the solenoids to lose their +12. I wanted to ask two questions, 1st can i go to autozone and just buy a run of the mill repair manual that will show me a wiring diagram? and second can someone tell me where the heck the wires go into the tranny so i can test the supply voltage?

Anyways doing diagnostics tests only those two errors came up, and i think i read somewhere on this forum that someone mentioned the tcc lockup and the 3/4 shifter share the same 12 volt power source I looked under the truck best i could but couldnt find anything except for the speedometer and i think the VSS ill have to get ramps to put it up on tomorrow but would appreciate if someone could tell me where on the tranny the wires for the solenoids are.


Thanks

The 3-4 shift/TCC lockup wires plug into the transmission on the driver's side, just above the pan. For working on these two circuits, I've found the wiring diagrams in Chilton's adequate (Information from Chiltons can be had online at www.autozone.com if you don't want to buy the print manual.)
To answer your other question, yes these two solenoids share a common power supply.

i appreciate you taking the time to help.

Thanks!!

Ok so far i was able to get a dvm and go under the truck, I'm getting 12 volts at the red wire to ground with ignition on. However the tcc and o/d solenoids are only showing 0.65 volts to ground does this mean both my solenoids are shot and i have to replace them?

So I understand -- You have the key on. With the key on, you have 12V to the red wire, but only 0.65 volts to the two wires between the solenoids and the PCM, correct? It would seem somewhat coincidental of both of them to fail like that, but is possible. It could also be a bad connection/broken wire between the transmission connector and the two solenoids. With the connector unplugged, can you verify that the solenoids are open (using the resistance setting on DVOM)? It sounds like it might be time to drop the pan and see what the wires look like
