The transmission on a Ford Focus is located in the same spot common to most automatic transmissions, near the engine. There may come a time when you need to remove it for replacement or repairs. This procedure is fairly expensive if you take the Focus to a professional mechanic, but it can be done at home with the proper tools, patience and some automotive knowledge.
Raise the front of the Focus with your floor jack and securely support it on the jack stands. Disconnect the back yoke and move the driveshaft forward using your crowbar. Slide the pan directly under the rear of the transmission and stick a rag in the back of the transmission to prevent fluid leakage.
Disconnect the modulator vacuum line and the transmission oil filler tube. Remove the clamp holding the speedometer cable to the transmission and slide it through the firewall to remove it. Disconnect the wires attached to the transmission.
Take your tube wrench and disconnect the cooler line from the transmission. Disconnect the rear transmission mount and the exhaust tube from the transmission. Using your wrench and socket set, remove the bell housing and then take off the cover over the transmission and engine.
Use your ratchet set to disconnect the mounting torque converter bolts beneath the bell housing. Take your crowbar and pry the converter off so that you have easy access to the bolts around the converter.
Place your transmission jack beneath the transmission oil pan and raise it so that it supports the transmission under the frame of the Focus. Use your jack clamps to securely attach the transmission to the transmission jack. Use your socket set to disconnect the cross member that supports the transmission.
Roll the transmission jack slowly toward the back of the Focus, allowing the transmission to lower along with it. Make sure that the transmission has plenty of clearance while lowering it and that nothing is still attached to it.
Be mindful of where components go as you are removing them from the transmission or from around the transmission. Keep screws and bolts in a safe place off to the side of your work area so you do not lose them. Make sure that when you are replacing the transmission, the torque converter is completely seated on a one-way clutch support.
