I have a 1993 Caravan with the 2.5 L engine and 3-speed auto. trans. The transmission is bad and my brother has a 1989 or 1990 Shadow with the 5-speed manual tranny. I am thinking about converting to the 5-speed and would like a few pointers since I have never attempted this before. Questions I have are do I need to change the ECM computer, do I need a shifter from another Caravan or will the Shadow shifter work, will the linkage from the Shadow work, etc.? Any help regarding this would be greatly appreciated.

 

So far I have been able to determine by myself that the computer in my 93 Caravan seems to be the same one used in my brother's shadow which is a 91. The 8th VIN is K for both. I would assume that the ECM in my Caravan would work with the 5-speed tranny? Some help from anyone is needed.

 

Sorry to have to bump but I never got any replies. I sure hope if anyone knows if there's a way to do this, i would like to know.

 

bolt it in, you may have to hunt down the shifter assembly from a junker. Those vans had 5 speeds in them, they are fairly rare and hard to find. Been about 5 years since I have seen one. The computer should work fine, they both did all of the same functions.

 

The problem is that I know the 1993's didn't come with standard shift. I have also heard that the axle lengths are different as well.

 

Hello guys,

I own a Caravan '93 with th 2.5 L 4 cyl. and the 3 speed AT, and want to convert to a manual tranny, same as KawiG5. Only difference is I took the motor out and it will never go back in, 'cause we want to convert it to electric power as a demo vehicle to promote EV's.

I just have the same question as KawiG5; since 1993's didn't come with standard shift I want to know if the axle lengths are different.
