So recently I converted my Galant Vr4 to Automatic and I couldnt seem to find any good info on the internet or really anywhere else on how to do or what parts I needed so I have decided to create this lil faq to give out all the information I have learned through my experience.
Now first of all you may be asking yourself why the hell anyone with a fast car would want to swap to automatic? Well its simple, for drag racing it cant be beat, not only can a auto trans shift faster than you ever will be able to but it also is more consistent and since during the lauch the entire driveline is preloaded you are far less likely to brake parts like axles, driveshafts t-cases etc etc.
First of all I will list all of the parts that are needed and their part numbers:
-A/T FlexPlate x2 MD735674
-Crank Bushing MD732972
-A/T Plate ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ MD952138
-Rear Engine Mount Bracket ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ MD143793
-Both Passenger Side mounts ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ MD143844 Trans Bracket, Body Side Mount
-Starters are Same
-The Inner shaft on the Axel on the Drivers Side
-Shifter w/Cable and Brackets
-A/T Rear Differential
-Torque converter bolts
-Automatic crankshaft bolts (to hold flexplates)
Now I will break down all parts of the swap and what needs to be done.
Motor Mounts - Some of the motor mounts on the trans are completely different and are impossible to swap over from your manual trans. Luckily both pieces to the front mount are the same and the mount on the drivers side for the engine can obviously be left alone. But both passenger side mounts are different. And on the rear of the trans the bracket that mounts on the trans is different but the mount that stays on the body of the car can stay.
Transfer Case and Differential - Both the transfer case and differential will need to be changed.
Shifter - Obviously you will need to install a shifter, which will bolt right in and then you will also need the single cable to connect it to the trans, you will also need to make sure you have the bracketry to connect the cable to the trans.
Shift control - Now this is where the swap may get a little difficult, there are two different ways to go about controlling the trans. You can either A) Buy a Transmission control computer, wiring harness and all sensors and let the computer control it. Or B.) Buy a IPT Shift controller, make some plates to cover the holes for the speed sensors on the trans and call it a day. I myself went with the Shift controller, it was the easiest method and now I can control my trans as if it were a stick by the push of a button. If you decide to try to piece together the computer system for the trans then all I can say is good luck, it wont be easy. There is one other method to control the trans and that would be with a AEM EMS or other Stand alone system but I wont even go into that.

I maybe missing something will double check and update.
