I need help diagnosing my problem before I go by parts. Story: I was trying to get my gauges working properly, removed the gauge pod, took a wire brush to gauge terminal, didnt realize key was on, *arch* *sparks* "ahh". Check all fuses, all okay. Reinstall gauges, some are working now (progress), but no tach or speedo, and no shift indicator. booo, feel like a dumbass. Symptoms: No tach, no Speedo, no shift indicator light, autotrans is stuck in 3rd gear, check engine light. Codes came up as follows: P0740, TCC enable solenoid circuit electrical. P0753, 1-2 shift solenoid. P0758, 2-3 shift solenoid, P0785 3-2 shift solenoid. P1860, TCC PWM Solenoid Circuit. I had VERY similar symptoms before when my ignition switch went, the tach and speedo still worked last time though. Any ideas of what it might be?
