Upgrading old Eaton auto shift 10 speed.

I would call Eaton and ask for transmission tech support. They should be able to tell you if what you want to do is possible and what is needed.

I've heard of people not being able to get replacement transmission ecm for the older autos. Might make sure that you can get parts as well

 

I know this sounds like a silly question, what do you mean by a ‘3 pedal’ and a ‘2 pedal’?

 

First generation autoshifts had a clutch pedal. Driver used the clutch only when starting and stopping. Once moving the transmission floated the gears. Newer autoshifts use an actuator to operate the clutch.

 

the 1st gen autoshift use 3 pedals (clutch, brake, fuel) the clutch pedal is required to start, stop, go into drive and reverse ONLY.

Gen 2 autoshift only had 2 pedals (brake, fuel) and yes the gen 2 was installed on c15 up to 2007 (a friend had one on his 2006 freightliner with a c15 acer)

To the OP yes you can change to the gen 2. The only main difference between gen 1 & gen 2 is
A: clutch assembly and bellhousing. Gen 1 uses a standard clutch and gen 2 uses a centrifugal clutch.. think go-cart.
B: programming. Your trucks ECM already has autoshift programming so it will just need upgraded programming for the newer gen 2 (dm2) Trans. Y9u will need to talk to then about how you want it programmed. This is not 1 program fits all...! Economy (slow shift ever gear 1-10) skip shift, your light do you really need 1,2,3,4,5, or just 3,5 (then trams will know if it can do it) aggressive when your heavy (the Trans will know) do you want slow (standard) shifts or do you want the Trans to burp the Jake's to drop the rpm's faster for a faster shift.. these are setting you can have changed.
C:clutch gen 1 uses the same clutch as all standard Trans around $1,700
Gen 2 (dm2) clutch is around $2,700
Gen 3 "advance" went back to the standard $1,700 clutch.
D: in cab shift controls, what you have now gen1 controls may or MAY NOT work with the gen 2 or three. Eaton makes controls made specifically for each brand of truck.. some are dash mounted push buttons, some are (volvo) buttons mounted in a box on the side of the seat, some are (freightliner) have a paddle on the steering column, my prostar has the buttons mounted next to the cup holder by my knee AND a secondly set (upshift, downshift, manual) in the steering wheel... price range $800 - $1,500


You will need to call eaton customer service to get the details and they can tell you exactly what you can change to and can give you all the part numbers (parts and programming) to do the change..

You may be able to upgrade to the Eaton gen 3 "advanced" if you can I would. It has some real advantages over the gen 2 (dm2). Default start drive is 2nd gear but you can change to 1st or 3rd any time you want. It has creeper mode where you can have it in 1st, 2nd, 3rd and bump the throttle to 800rpm then lift and the truck will go back to idle but keep the clutch engaged their by creeping along at 3-5 mph (real handy in traffic) also has auto cost mode. What this does is when your using you cc and you start to crest a hill (big or small) it you go over your cc setting the clutch will disengage and let the engine drop to idle speed and let the truck roll up to 3-5 mph over your cc setting then re-engage the clutch so the engine and Jake's can hold your speed back... most of the time you'll never know it unless you look down and see the gear indicator flashing or see the rpm's at idle... this does save you some on fuel.

 

That’s what I thought, but figured best to ask.
Just always heard it referred to as an ‘auto shift with a clutch. Drove plenty of auto shifts without the clutch. Me personally prefer a manual.

 

There is a guy in Chicago who pairs Volvo ishifts with 12.7 Detroit. I guess anything is possible if money is not an issue
