To replace the ignition switch remove the horn pad be careful the wire is still attached to the turn signal switch the plastic piece push down and turn it comes out then remove snap ring on the end off the steering wheel then nut place a dot of finger nail polish on the shaft and wheel for alignment purposes use a steering wheel puller once off then install a lock plate puller compress down and remove lock ring once removed (lock plate) this is spline d to go on one way then take the cancel cam off (slides off) remove turn signal lever screw and turn signal screws lift up to gain access to the ignition switch retaining bolt a small piece of plastic is covering the screw that is the key buzzer switch it just pulls out be careful not to drop the spring steel retainer down the column it does not come out that easy and does not install that easy either. Place ignition in the on position remove and put the new one in the same way this allows the key buzzer to go in with out interference from the plastic shoe that's part of the switch. the lock plate tool can be rented from the parts store.

My speedometer does not work and feels like my car is not changing gears

I just had this problem two weeks ago, the problem is in the iginition switch which is not sending an electrical current to the fuse that registers your RPM's which will kill the speedomoter too. when this occurs the transmission will set itself on overdrive and not actually do any gear changes so you will be really sluggish until you reach about 40-50mphs then you should be fine. once the iginition switch is fixed, you should be back to normal.
