Is it "standalone" or can you make one standalone?

I guess what I'm really wondering:

If I have a manual trans Dmax, can I put an Allison in it without tying it into the PCM?

I feel kinda wierd answering this since you know way more about this stuff than me, but as far as I understand, the Alli TCM is fully independent, which is why guys are able to put them behind a Cummins, etc.

So based on this, I'd say "YES" based on the TCM/PCM end of things, it could be done.

What are you trying to do? Allison has a stand alone computer ( available from Allison). There is another company that has one as well and I hope to be trying it out soon. Call me in the am.

I don't know squat, I just talk alot! :D

About the alli, that's what I was guessing. Interesting.

That computer might be stand alone, but it has to interface with the engine somehow.

It defuels. It calculates TQ/HP to decide upshift or downshift or same gear.

There has to be a link between the two.

It won't defuel if it doesn't see a shift.

The standalone Ally computer I would guess would need either a TPS (throttle) input and read the RPM or the MAF (no engine vacuum available). Otherwise it would always shift up at the same RPM and down at the same RPM, which would be useless except for racing.

It could do it just off RPM and TPS, but whether that's the case, I don't know.

It would be nice to comprehend the stand alone better. Depending on how much TQ is required to just turn the thing, I could see that tranny behind a large cubic inch small block jeep. :ro)
