Question:

Hi Anthony,
I was wondering if you could tell me how difficult it is to convert an 03 Lancer automatic to a manual transmission. Also what is your estimate of the cost of the job if I was to do it myself, and if I was to get it done by a mechanic. Thanks alot.

Answer: Jenson,
Converting a newer car like your '03 Lancer from an auto to a standard would be extremely difficult. Your automatic has additional computers, sensors, wiring, and lots of other hardware that would all need to be modified and adapted to fit a manual transmission. The engine itself would need slight modifications.

Also, a new rebuilt manual transmission for '03 Lancer can cost anywhere from $2000-$2500. And labor costs would probably border on $800-$1000 easily for a mechanic cost. And unless you have a garage with a lift, high-torque air ratchet, lots of space, a large array of mechanic specialy tools, lots of time and money, I would recommend you not attempt this yourself.

If you deadset on changing your transmission, trade your car up for a manual transmission model. You'll save lots of time, and probably money as well.
Good luck!
