If the transmission doesn't see the right fluid pressures it will stay in second gear to allow you to get it off the road without tearing itself up.
A 93 Deville that wont shift from second gear has most likely got an internal transmission problem. Unless the linkage is mis-adjusted, then the problem is onside of the transmission.
The transmission computer will default to second gear only when it detects a malfunction and sets a code.

A seized up transmission can cause a Volkswagen Golf with an automatic transmission to not shift and racing RMPs after second. A worn gear can also prevent shifting.
