How do you change the tranny on a 93 sc2?

Answer 1

transmission removal is a serious job, and will require many tools, and lots of time.

Lower:

first raise the vehicle and support it well using jack stands. make sure the jack stands are not under the subframe of the vehicle, but on the pinch welds of the body. start by draining the Transmission Fluid. from under the vehicle, remove the 6 bolts in the lower engine to transmission brace, there are also two 10mm bolts in the exhaust that must come out. remove the exhaust hangers from in front of the catylitic converter. Remove the flywheel to torque coverter bolts (automatic) Unbolt the passanger side CV axle support bearing housing from back of engine block. Unbolt the two lower transmission mounting bolts, one on the front of the motor, other on the rear. Unbolt the powersteering rack and pinion, remove the brake line fastner from the far rear of the subframe, remove the three 13mm nuts from the bottom portion of the exhaust manifold. unplug the transmission speed sensor, remove the shift cable from the nutural safety switch. the trans shift cable is held into the body of the transmission by pressure clips. they are a pain in the rear but you can get them if you work at them long enough. remove the wireing harness from the nutural safety switch.

Sides:

remove front tires. Unbolt strut from steering spindle using 18mm wrench to hold one side, and a 21mm socket to turn the other side. use a 18mm socket to remove the lock nut on the Tie rod end. The tie rod end usually is stuck in place, use a small 3 lb sledge and hit the spindle where the tie rod goes though. becarefull not to hit the tie rod. remove the axle nut 30mm. use a air hammer to push the axle through the spindle. Use a CV Axle cup on a slide hammer to remove the axle from the transmission. If these tools are not available, a small to mid size prybar fom underneith will work as well. this must be done on both sides. On the driver side, remove the two 10mm bolts in the lower transmission mount.

Up top:

Remove the air intake tube along with air filter housing. remove the battery. remove the battery tray, there is a hidden bolt in the driver side wheel well that goes through the body into the lower part of the tray, 13mm. remove the wireing harness to the top of the transmission (7mm) remove all the wireing connectors on the front of the transmisison. remove transmission lines from front of transmission, you can usually pinch the plastic ends together and they pop right out. Remove the dog bone arm assembly from the front of the transmission to the body. support the engine using a "T" style brace across the strut towers, and from the rear cowl to front radiator support. Use wire and tie the radiator fan shroud to the "T" brace. From underneith the vehicle loosen the two front frame bolts. from outside the car, on either side, loosen and remove the two rear frame bolts. the subframe does have some weight, about 60lbs, so be sure it doesnt fall on you. remove the subframe from under the vehicle. if you have a flat plate adaptor for your jack, now is the time to use it. if not, the transmission only weighs about 60lbs. as you loosen the two top transmission bolts be aware that the transmission will basically fall to the ground. Reinstallation is just opposite of removal. its time consuming, but after you have done about a dozen.... you kind of get used to it :)
