Converting To Electric Q. I've got an unusual one here. Is it possible to valve a Dodge transmission (3.0 3 speed) to work when idle goes to 0? I'm thinking on converting my '89 Caravan to electric and I'd prefer to keep the AT rather than try and finagle a stick in.

Problem is, when an electric comes to a stop, there's no rpm's. Also when an electric takes off, there's full power available at 1 RPM. I'm just wondering if there is a way to set up an automatic to work under these circumstances? Maybe setting up the Lock-up Solenoid so it's always locked? Could I bypass the torque converter, or is it the fluid pump for the rest of the transmissions workings? Could I substitute a separate hydraulic pump for that, or would that require more than I make in a year to configure the transmission to use?

I'm willing to try any idea (within reason) that could make this work, so if you've got a wild idea that just MIGHT work, please pass it on. I'm probably looking at about 135-175 hp, 225-300 ft lbs torque, and a redline of around 4000-4500 rpm. I'd really appreciate any and all input on this. If you have any ideas, please feel free.

Thanks in advance,

A. This sounds like a very interesting project. I'd be interested to know what you are using for a power plant, batteries and charging.

I have never thought about doing something like this to a transmission so I'm a little short of suggestions. However, it would seem to me that an automatic transmission would not be the ideal way to go. To me it would seem a manual transmission would be better. It's a direct connection and does not rely on hydraulics to engage it. It also has less mass to get moving than an automatic. If you're determined to keep the automatic, I would guess locking the torque converter permanently would be your best bet. it would be simple enough to do, just apply voltage to the lock-up solenoid and that will keep it engaged.

How the lack of fluid pressure would effect the transmission, I don't know. It would seem that if all you're using is the lock-up, you wouldn't need pressure. As for hooking up an external pump, you'd have a better chance of finding a snowball under Satan's pillow.

I wish I could be more help to you, but I just have no experience in something like this. I would be interested in how you make out. Perhaps I could do a series of articles based on your experiences with this project. I'm sure others would find it interesting as well.
