I need steps of removing a transmission from 1981 chevy tow truck

• Remove the TV cable or transmission throttle cable from the carburetor or throttle body. Remove the upper bolt holding the transmission dip stick but do not remove the tube. Disconnect the negative cable to the battery. Drain the transmission fluid by removing the transmission pan. Replace the pan after draining the fluid.
  Remove the shift linkage and the wires to the neutral safety switch. Remove the speedometer cable by unscrewing the cap at the point it enters the drive gear in the tailshaft. If it has an electronic speedometer, disconnect the electrical connector.
  

• Install the engine support stand above the engine. Remove the CV joints. Remove all electrical connectors from the transmission. Remove the bolts in the torque converter. Place the floor jack under the transmission. Raise the transmission just enough to support it. Remove the transmission mounts. Lower the transmission enough to have access to remove all the transmission bolts. On a rear wheel drive vehicle, remove the bolts in the bottom of the transmission mount. Raise the transmission enough to remove the cross member.
  Once the bolts are out remove the cross member and then lower the transmission. Remove the dip stick tube from the transmission by lifting up. If it is hard to come out tap its mounting bracket with something and it will come up and out. Support the transmission securely on the jack. Using a flat head, separate the transmission from the engine. Lower the transmission.

Tammie,
You are not supplying enough info. Please provide engine size, transmission type and I need to know if this is a 1 ton, 2 ton or 3 ton truck to give you that info. Also, it would help to provide the VIN [Vehicle Identification Number]
