Possibly a bad wheel speed sensor. Get the DTC (diag trouble code) from the car using an OBD/CAN scanner while the light is on.

After 90k miles, you probably need to clean the MAFs and throttle bodies.

Possibly a synchronizer problem or you may need to change the gear lube.
If you plan on doing you own diagnostics and/or repairs, an OBD/CAN scanner/monitor and the FSM (see link in my sig) are invaluable resources.
