Guys, first my gas guage on my '76 GMC is not reading right. When installing my transmission,the wire leading from my gas guage to the gas tank, broke! My Gas hand was showing full! I knew this was not correct, when i fixed the wire and turned the switch it went all the way to empty! Went to the gas station and it only held 5 gallons! What's wrong? And the gas hand did not move!
Secondly, my speedometer needle points straight down? I can't remember if I broke something off or not. It does move but it may not be accurate!
Help
