Adapting a new Mopar 5-spd Auto: Is it possible?
« on: September 28, 2004 - 04:45:45 PM »
I was wondering (hopefully for future reference ;D) if the new 300C five-speed autostick transmission could be adapted to work without computer controls. If it can, could it still work as an auto stick, or be adapted to a sequential slap-stik type set-up? In addition, could it be mounted to, say, a 440?

Thanks.

Not knowing alot about the 300C cars but heres what i think....A) No it won't work because you have to have the computer for most of these now day cars other wise its all screwed up because the computers tell when to shift and what not....you could get it to mount to a 440 if you tried hardenough...also you might be able to by pass the electronics on some of that stuff but i dout it.. enless your an electronics wizz..another words..Its almost impossible to do that swap enless your made of money.

I'm going to venture towards NO.... here's why....

The ECM in the new cars are hardcoded with serial number of the trans and engine combo's... you'd have to have BOTH for it to work right. As well, there are so many shift solenoids and sensors in the new transmissions, that it would be nearly impossible for you to nix the computer and try running it without it. As far as adapting it to a 440, or any other older engine for that matter... I'm sure it could/will be done, just depends how much someone wants to drop on doing the conversion.... ::) ::)

My suggestion, write to a performance company that does a lot of muscle car conversions (pick up a copy of MM for ideas for companies) and see what they say. Who knows, you might find someone that's interested in your idea!! ;)

Actually... ijust now thought about it alittle more..and if you could fine some relays and junk you oculd probly make your own computer to control when to shift and what not..just a matter of hookin stuff up right also...depending on what your plans are for your 440 i'm not sure if it could handle alot of tq..it might last awhile but it might take the tranny out fairly soon also.

Well, I wanted to try and save my wallet this way. If there was/is a cheap(ish) and simple way to do this conversion, I could track down a 300C or Magnum that had gotten into a accident, and pull the tranny.

Trust me....you won't be saving money enless you swap the motor also and then it will still be quit expensive...once you buy the car pull the tranny figure out how to wire it up and then to get all the gages working since most of them are electronic...it will be expensive and very time consuming.

 At the least, it has some sort of electronic lock-up torque converter. That has a heat sensor wired into it as well that won't let the tranny go into overdrive until the engine/tranny is warm enough.  At least this is how it is on my Ram truck with Hemi + auto tranny.  I imagine they adopted the same tranny for use in the passenger cars.
  Plus you will need some sort of adapter flange from 440 to new style tranny...

I don't know if the bolt pattern is the same on the 5.7 and 5.9 but if they are a 518 tranny (od) can be wired up to shift into OD and what not and theres ways around the heat sensor.  I could probably figure it out. but then again your wanting to mate it to a 440 and a 440 would destroy a 518 in no time.   heres a question for someone...are the V10 bolt patterns the same as a Bigblock? I think they are the same as a cummins but not sure...I want to be the first one to put a 5.9 Cummins in a A-Bod.  ;D ;D
