EOC in FWD Auto Buick possible with RV upgrade>?

[rmay635703]

I am not sure such a thing exists for a 98 Buick Lesabre (or our 93 suburban we would like to tow along for moving our trailer instead of moving it w/ a 40ft 11mpg diesel pusher at the fairs) but apparently the
RV crowd commonly adds an electric tranny pump in parallel with the hydraulic so they can flat tow autos behind the RV, I am curious if this would be a good way for those of us invested in a blasted auto to break the MPG barrier enabling EOC and flat tow.

Has anyone ever made a DIY Electric transmission pump mod?

Wow, that would be awesome! I'd love to EOC in my Buick also without fear of grenading the transmission.

The instruction manual they provide shows the fluid being pumped from the pan into the return line. Simple concept, bear of an execution.

Hmm, I am sure a mechanic could do it, I wonder how far you have to break down to get into the buick since it is tough to get in there so to say.

Main issue of coarse is the $850 price tag, not sure I can make that back anytime soon in FE savings.

Now if we could get the bloody auto companies to cooperate and build the transmission from the factory like the ones at Oshkosh truck where you can coast power off at any speed for any duration we would be getting somewhere.

The problem with the Buick is the pan is shallow. Not much room for a fitting on the sides, and you'd have to run a lot of hose to get to wherever the pump was.

Wiring it in would be hard, too. We'd need a relay of some kind to run the pump whenever the engine was off and the transmission in neutral. It would need to be somewhat automated to kick in quickly after engine-off, then disengage on re-start. Then there's the separate issue of wiring in a kill switch. Plus getting all of it to play nicely. And remembering to shift into N before doing all this..

On the DIY Electric Car website, there was mention of using a cheap fuel pump to pressurize an automatic transmission.
