1999 saturn coupe gear shifter

We have a 1999 Saturn Coupe automatic. The shifter feels very loose and I cannot shift into any gear. Someone told me it might be the quick shift. What is this and will it cost me alot to repair?

i'm not sure what is ment by "quick shift", but problems simular to yours are cause but problems with the shifter cables. most commonly a bushing at end of the cable under the shifter itself will give out. saturn only sells the cable as a complete unit. but some people have started to make their own bushings and you can sometimes find one for sale on ebay
