Could be either, any trouble codes stored in the computer in your car or any pending trouble codes? Check the transmission fluid level, check for leaks if it is low, perhaps try servicing the transmission but most likely a transmission that is going out.

Thank you for the answer. No trouble codes or check engine light on. Had trans oil changed was slightly discolored and screens were clean no particles in pan. Did misfire once when shuddering. Was tuned up 20,000 miles ago.

GM HAD A WHOLE BUNCH OF MODELS THAT HAD FAULTY TRANSMISSION CONTROL MODULES (with recalls on file) MY '94 WAS DROPPING INTO NEUTRAL AT HIGH SPEEDS FOR A MINUTE OR TWO. ALSO TRY FLUSHING OUT THE 'ENTIRE' TRANNY -* INCLUDING CONVERTER* FOR LIKE $100. THAT WOULD HAVE SAVED ME $1,100 FOR FINALLY BLOWING A SECOND TRANNY THAT SOMEONE POURED BRAKE FLUID INTO ! ! ! .
