2002 GMC Envoy Question: My car won't accelerate when I push the gas,The RPM goes up but the truck coasts

My car won't accelerate when I push the gas,The RPM goes up but the truck coasts along, Could it be the computer or do I need to replace the transmisson? It burns gas when I drive it... it never did that before... -
Answer 1
Have you checked the trans. fluid? It should burn gas when you drive! Do you mean burns more gas than usual? that is prob. due to trans. slipping. -
