Have check engine, the computer says it needs the shift solenoid, the problem is it will not shift from 2nd to 3rd gear on an automatic transmission. Also found a vacuum line near to transmission disconnected but not sure where it goes. How much is the cost to replace them? Do I need a new transmission? It turns on fine and shifts fine from 1st to 2nd gear. Has close to 250,000 miles, never had transmission problem before.

yes you would most likely need to replace your shift solenoids A & C or B. and it will cost around $175-275, but you can buy the parts and do it yourself at home and just would be much cheaper.
