My 2013 Ford CMAX with 130,000 miles on it now has a very loud whine whenever gas engine is on. If it goes electric only, the whine disappears. Ford dealer wants $1400.00 to open it up and inspect if, they think it is transmission. To replace transmission is $8,400.00 parts and labor. Car is worth $5,200. Could I find someone to replace transmission with a rebuilt one (rebuilt trans is $2,700) Thoughts?
