Most likely the transmission has lost overdrive and is not shifting to the highest gear. A common GM failure! Time for a transmission rebuild or a new vehicle. Being 22 years old I think a new vehicle is your best option!! Hope that helps! Jim

A transmission flush is the kiss of death for an older model transmission. Especially a GM! Jim
