I found my recent 2000 2500 truck aquisition very annoying constantly going in and out of lockup in the city or in hilly terrain so I installed a switch on the dash to disable the lockup solenoid. The extra lock-up sequence in 3rd gear was even more annoying as the 97 does not do this. This is not the "mystery switch" that forces a lockup and in fact is the opposite. The mystery switch is vey hard on the soft parts in the tranny when changing gears locked.I had done this in my 97 2500 and all I had to do was put a simple switch in to open the circuit to the solenoid. Last week I tried the same thing in the 2000 but it immediately went into 3rd gear limp mode. New software in the 2000 PCM so I had to take a different tact. I finally ended up switching in a 150 ohm 5 Watt resistor connected to switched 12V with a relay to make the PCM think the solenoid was still connected. The relay is activated with a round rocker switch on the dash that looks factory. The relay has a 75 ohm coil but the higher the resistance that does the job the less current required. If anyone else is interested I can post the circuit diagram. I basically cut and spliced in the circuit in series with the OR/BK pin 11 on connector C2 (middle of the three) on the PCM. No codes get set with this circuit. The relay can be eliminated by using a STDP switch but its hard to find one that looks factory. The switch has to be 2 position only and not a 3 position or a code will be set saying there is an "open solenoid circuit". The hardware is mounted immediately beside the drivers side hood hinge on the small ledge inside a small electrical box with a 4 wire trailer connector. This is my 1st post on this excellent site so I will fill in the signature once I figure out how.
