is the service engine soon light on? have it scanned to see if there are any codes present. driving it in 4hi should be a problem but 4lo would be a problem it wouldnt probably get up to 55mph. but anyway i would check for codes and see if there are any technical service bulletins, available on many sites.

The transfer case electroinc encoder and dash switches were troublesome.
