You need to check for trouble codes.
The transmission is either locked in 2nd because of an internal fault or the controls are not responding due to an error detected.

CHECK ENGINE Light/Malfunction Indicator Light (MIL)

Turn ignition on. Connect a jumper wire between Self-Test Input (STI) pigtail and signal return (SIG RTN) terminal of Data Link Connector (DLC). See Fig. 2.

MIL would flash the trouble codes.

You need to find the cause of the problem and rectify it. Worse case scenario is a transmission replacement. Cheapest would be a loose or contaminated wireharness connector.

Check for trouble codes first. Since reverse is slipping intermittently, it does not bode well. Possible cause is leaking pressure lines/clutches which requires a rebuild or transmission replacement.
