This trucks speedo is 10 mph to the slow side we are just out having a little fun. mods are: Custom MCC, s475, traction bars, and deleted. We are attempting to push the stock 68RFE to the absolute limits then... destroy it

Very nice!!!
No OD tune?
yes it is a OD Tune
She moves out very well! It hardly sounds like the engine is even working. Is that a stock transmission?
Has anyone shoved a 68 behind a 5.9 yet? I was wondering if there is a controller available to do that

That double overdrive would be nice in a 5.9. But your right that one would need a stand alone controller. Hopefully someone is working on that project to bring it to market.
It would be interesting. Having a more robust trans under you would be exciting. . . .
As far as I know, it would be a complete bolt in with maybe a modified trans mounting. It's the electrics that could be a problem.
There is a way to make the 45, 46 shift without a controller. The 48 has a different governor. I would have to study the 68.

Yes it is stock for now. The goal is test the limits of the stock trans destroy it and put in a built one. Steve the electronics of the 68 are far more advanced than the old electronically controlled trans. I spent the better part of a month to jump bus power into the wiring harness to get the trans to work with factory pcm. No success I will make a full thread on it soon with wiring diagrams.
What about going from the ECM to the trans controller. Maybe an interface is needed between them. CAN would use a different language, so pre-2006 is where it would have to be concentrated. It is probably still an analog to the trans PCM
