Got in the ole 98 silverado this morning, no gear indicator light, hard shift(shudder) into D, and apperantly stuck in 3rd gear. just had my trany totally rebuilt in july($1700), so i call the Mech. for warrenty. Turns out im on day 93 of a 90 day warrenty, good guy is gonna help me out anyway. I explain the symptoms he tells me tranny is fine, its electrical. so i go get the codes read and this is what it said... -02 heater circut malfunction(non related i assume) -TCC circut malfunction -Shift solenoid A circut electrical -Shift solenoid B circut electrical -Manufacturer control transmission -Shift/Timing Solenoid Malfunction I have been told its likely a problem with a power wire. Has anyone had expearience with this before? where should i start looking? or should i just take it in to a mech?
