How to Take Out a Transmissionby Don Bowman
When removing a transmission, caution should be observed, as the unit is quite heavy. The transmission can be removed on the ground with a floor jack, however the floor jack gives only support and has a small lifting surface, so it becomes very unstable. A regular transmission jack for under the car should be used. The transmission should also be drained of fluid or it will pour out when the transmission is angled down.
Raise and support the vehicle on jack stands. Drain the transmission by placing a container under the transmission and remove the pan. Replace the pan when finished draining. Remove the drive shaft and place aside.
Remove the front cover on the lower part of the transmission. This front cover conceals the torque converter. Remove the torque converter bolts. Insert the screwdriver in between the teeth on the flexplate to prevent turning as the bolts are removed.
Lift the transmission with the floor jack just enough to take the weight off of the transmission mount. Remove the bolts in the transmission mount and the frame bolts in the cross member and remove the cross member.
Remove the gearshift linkage. Just remove the cable and support bracket and move out of the way. Remove the transmission cooler lines and cap them to prevent leakage. Remove the electrical connectors. Remove the transmission kick down or tv-cable from the carburetor or throttle body.
Remove the transmission dipstick. Remove the bolt holding it to the bell housing and then pull it straight up. Remove the speedometer cable or electrical connector if it uses a speed sensor. Remove all the bolts in the transmission bell housing.
Remove the transmission by raising the jack a little so that the transmission is not at too great an angle. Use the screwdriver to pry it loose at the bell housing and while supporting it on the jack, pull it rearward and out.
