    A-413 Conversion

    I need parts to convert my 1987 Dodge Daytona Shelby Z T-Top to an Automatic from an A-555 transmission. Why? well because I do alot of commuting...efficiency is the key.

    You shouldn't need many parts to go that way. Trans, flexplate, torque converter, shifter. You can change the pedals if you want but you don't have to.

    By the way, a manual trans is much more efficient than an automatic. Especially an automatic with no lock-up converter or overdrive... like the 413.

    Sitting in city traffic an automatic is more efficient on your knee and clutch disc wear. If thats one of your efficiency measures ?

    We have lockup 413's and with the right gearing combo its not terrible on the highway.

    On top of what contrapion22 said. You'll need a trans mount, flexplate to flywheel bolts, TC bolts (4), a trans cooler, and the pigtail from the neutral safety switch for the reverse lights (2 outside pins)

    If you're looking for fuel efficiency- you're going in the wrong direction, the overdrive 5th gear and a no slip clutch is better. It'll get you lower hyway speeds and that means better fuel economy.

    I just did this swap in late August, it's not bad, but not something I did for efficiency.

    Re: A-413 Conversion

    automatic is definitely good if you do a lot of around town or sit in traffic. a 3.02FD with lockup should get you 32mpg if you keep to 60-65mph. you could also go 2.78 or even 2.60 if you do a lot of highway and not worried about losing some grunt off the line. i was thinking of going with a built auto with 2.60 and lockup on my 2.5T2 K wagon project before deciding to convert to a 5spd so i could have the best of both worlds.
