we are running a power glide transmission that has en electric shifter. it takes power to hold the solenoid back. however this weekend while racing first pass out i went to go stage and noticed the solenoid did not want to cock back and hold. it acts as it is not getting power to it, however when we get back to the trailer and shut the car off the solenoid cocks. it is running power from the delay box so there is a constant power going to it. also sometimes when i let go of the transbreak button it shifts into second right away. the batteries are charges so i know it is not a low volt problem. does anyone have the same problem or ran across this? we are also not running a alternator on the engine.
