No foreward motion on 1996 Volkswagen Golf

Volkswagen Automatic Transmission problem:
The check engine light came on. Scan by AutoZone Tech printed out to Transmission Speed Selector Switch. Shortly afterward car jumped out of gear at speed. Downshifting manually to lower speed (eg. 3rd) restored function and could be upshifted to top gear (drive). Car began slipping between shifts. Then almost complete loss of forward function by transmission. Reverse is fine. Could this be an electrical problerm? What to do
