[Diy_efi] Chrysler transaxle as stand-alone

[Ernest Buckler]

Don,
Thanks for the reply, I'm heading for our Pull n Save salvage yard soon to 
get a close look.  Will be very interested in what you figure out.
Ernest

The possibilities with the trans are endless. You could use it with a plate 
on the torque converter and run a short drive shaft to an engine like the 
Corvette does, Yard carts,sand buggies hot garden tractor, I would really 
like find out how to run the trans with a stand alone module.

Don,
I'd like to stay in touch re this trans, as I 'm also thinking of using it
another project due to its compact dimensions.

Is that trans the front drive transaxle for the Concord ?  That transaxle is
the most compact I've seen and wondered could you run it with just  a trans
module or does it run from the car
 PCM ?

I've got source to pressure transducers from Chrysler 45RFE
transmissions.  They mount external to the trans.  I work for company
that rebuilds them, and every unit gets a new one... Many are probably
fine.  The trans runs from 35-200 psi at times..so It should have broad
range.

Let me know if you are interested. Just pay shipping.

David,

Great info on the OEM sensors.  I didn't know they were that crappy
(tech
term).  I looked at the link you gave.  Nice site, they actually give
good
info on the products.

Thanks,

Dan Nicoson

  I 've used a "sender" for a transducer before and it worked. But only
after I carefully logged the resistance versus pressure curve and
programmed
a PIC to interpolate this table into a linear "transducer-like" output.
  Still cost less than a real transducer but what a PITA just to save a
few
$.  The curve on these elcheapo senders is horrible. Repeatability
sucks,
and they degrade over time.  The sensing element is a bourdon tube with
a
copper "arm" rubbing on nichrome wire.  It wears noticabley in a few
hundred
hours of use.
  The following company supplies the OEM I work for with transducers
that
are not too bad expensive and are a very nice piece. We use the 300
series
in a pressure/ vac; 100 PSIa, 150PSIa, 1000PSIa and 10,000 PSIa
versions.
I've 'copped' a couple used ones and have great success datalogging with
them while tuning my engine.
  They even sell online.

  Hope this saves you some time!
