New parts cost transmission / $3626.07, ECM / $1008.92, wiring harness / $867.00, total / $5501.99
Used parts cost about half that if available $2750.00
Labor would cost $2500.00
New parts plus labor $8000.00 plus
Used parts plus labor $5250.00 plus
car value by Kelley Blue Book.. Excellent $4520.00, Very Good $4220.00, Good $4070.00, and Fair $3370.00
As you can see the repair cost more than the car is worth at the excellent price.
depends on how much u love your car, i say no
