I just installed the turbo 400 onto my truck, I forgot to put fluid in the torque converter. The truck will not in gauge the transmission. Is this because I didn't put fluid in the torque converter?

torque converter uses a lot of ATF fluid and if empty tranny will not function or move the truck
have to fill the converter
do not run it long as you may damage converter

good luck
