That would work on an "RE" transmission that is electronically shifted.  Mine is all hydraulic and does not have a lock up torque converter.

Ok, I just looked closer, it will work on an RH, but it also wants to see a lockup torque converter and needs a throttle position sensor that it can access.  I could rig one, but probably not worth it.

It has the option of no converter clutch and they can supply a TPS for a carburetted engine. You are running out of excuses. :)rotflmao  Looks like a decent unit. I would like to see one like that for the 4l80E GM trans at that price.

No excuse needed for doing a cool combo like this one though.

I looked deeper at it.  It could be a neat product.  I am going to keep that one in mind.  I want to prove the transmission out for a while first with my switch.  I need to feel confident all the issues are put to bed.

You know I am just busting your stones. I am waiting for my suggestion of the 13 speed to get the best of you, it is going to happen. The voices are getting louder. :D :D

The 13 speed is not going to happen Rick.  I went through hell with this conversion, although most was my own fault.  I really want to focus on enjoying the coach.  My last major upgrades will be a new modern AC unit for the roof with a wall thermostat (I travel with animals), and a full repaint and window rebuilds.  Some minor upgrades as well like new dash and modern insturments and switches, modern lighting, etc., are also planned, but they are not huge changes.  Other than that, nothing major is planned.  At some point the motor will need a full rebuild and I will plan that one carefully and build it the best I can for how I use it with lots of low end torque and efficiency (yes, I said efficiency regarding a 440) in mind.  No diesel swaps, no flux capacitors, hybrid drives, warp generators, or cloaking devices.... sorry.

Listen to the voices! Diesels are efficient. The trans will bolt right on with a class three bell housing (or #3, I can never remember which) All you need is a hole in the floor. No electronics, No 50 gallons of lost transmission fluid. Listen to the voices!!!














Boy am I glad I live a LONG ways away from you!! At least right now anyways. :)rotflmao :)rotflmao :)rotflmao :)rotflmao

The last time I listened to the voices it ended up very badly for me.  So, I shall resist.  Diesels are more efficient, but I really do not want to do that.  I simply do not put the miles on the coach to make that worth it.  One could argue the same for the overdrive, but it is so much more quiet and relaxed at 2100 rpm vs over 3k.  That in itself makes it worth it.  As it sits, my mileage is not bad at 7-8.5.  I am still curious what it will do with the transmission working properly.  Even if I only pick up 1 - 1.5 mpg I will be happy.  I tend to drive hard, so my mileage will suffer.

But bottom line is that I am going to take the next year and just work on details.  Continue on really jazzing her up.  People are so blown away when they walk inside her, I just want to finish that.  Some new modern back splashes, LED puck lighting, and a bunch of small details that have been neglected.  And bottom line, use her.  Go camping.

OK, OK, I will stop pestering you. Just hope I don't trip over a 671 Detroit laying around anywhere. That and a Road Ranger and MY wheels will be turning!

You KNOW I was interested in that project since it was so off the wall and technical. AND he had the balls to test drive it so far with little preparation. And on top of all that he put up with all of my crap! :D :D :D

You get to a point where you do not want to work on the beast any more, I think I may have set my timing to late , But cant get up the energy to recheck it (it is not as easy as usual) I am happy to just get in and drive, With only checking fluids and air pressure ! Frank

What would the mpg be with one of those?  They aren't very fuel efficient are they?

On a vehicle as light as a motorhome it would be probably 12-15. You could also hook it into an Allison 6 speed auto but Detroits were pretty sensitive to rpm, they had a pretty small range they liked to be in. Especially the 6 cylinders. I drove a 1971 Autocar heavy tractor with a 12V71 12 cylinder Detroit and that thing would pull like you would not believe between 1600 and 1800 RPM. It pulled hard all the way down to 1200 but at 1600 it would spin the tires with anything less than 10,000 lbs on the axles. But man it was a thirsty beast! It got 4-6 MPG at best. Being a two stroke they were not the most efficient fuel engine but damn they sound good! :D
