you might be able to just find the whole working set and transplant it to your bus. and then reprogram your engine computer. even if you had to buy a reman trans but could find the electronics.. the electronics cost as much as the transmission!

I thought it was you that said the 3060 was electronic and the 643 was dumb as a box of rocks. Regardless of who said it, I took that to mean that I couldn't get an 8.3L of '99 to use a 3060. When I saw Lincoln post that he bought his bus with that combo, I has options!!


I did a google before buying the bus and everything looked available. Of course I didn't go into any kind of detail but the 3060 tranny and tranny controller were $1000~$1200 each off of E-bay, CL, and rebuild sites. No clue what a shiny brand new one would cost.

just because the engine is mechanical doesnt mean it cant run an electronic transmission.. I have zero knowledge of the 8.3.. I was thiunking it was electronic.. but it may be all mechanical..

the transmission can operate solely off a TPS (how much your foot is down on the go pedal) sensor.. which a mechanical engine can have on the throttle cable..

Yes...the new gen Allies only need a TPS to talk to an all mechanical motor. That's the main reason I went that rote. With the older trannies, the programming and harness issues can be a nightmare

Found a pic of the tranny mounts. They are the same on each side. Just your basic Volvo rubber hockey puck engine mount in between.




And do you know off hand where your engine mounts are located? Front, middle, rear? That can make a big difference in how the trans gets loaded.

I've no idea if I'm mechanical or electrical. When looking at the buses for sale, all of the '99s had the 643, the '02s had the 3060. I assumed there was a generation gap there. The '02 with 8.3L and 3060 has a different routing for the air intake and/or turbo than the '99 with 8.3L and 643. I doubt that's because of the tranny tho. This furthered my belief that there was a generational thing going on. There are a number of things that are different too. Dash, cosmetic, and the usual stuff you'd expect even in cars.

Very cool!
Chris, you're awesome for doing this! You're the go-to guy for all info concerning 444's and short buses! I can't wait to see this in person, and pick your brain a bit.
I'm thinking this may be just the ticket for my daily driven Duck.

Phfft. He needs to get busy with 8.3Ls and 3060s. I've got a donor bus for trying a swap.

I like that he's taking a bus with lower-spec stuff and improving it.
8.3 and 3060 doesn't really need as much help.

No, but an 8.3L and 643 does.

an 8.3 with a 643's most costr effective way to improve is to regear the rear and turn up the smoke on the 8.3. you have the power and a good transmission you just need to lower the RPMs a bit..
