New to diesels...so what's with the...

[daytona]

Duramax LB7, the LLY before a certin date and the LLY after a certin date? My NEW van a 2006 Chevrolet 3500 witha 6.6L Duramax LLY-Engine and a MN8-4, Automatic Transmission, HMD 4L80E-HD (supposedly a new transmisison design) because the Allsion will not fit.... is at Quigely as we speak getting the 4X4 system installed ...besides other options.

Can one tell from the VIN number which even it has? And how or who has the info to cypher this?

 

No doubt I would interested in getting a performace unit to add to the enging, but all I have asked don't seem interested becasue of the "VAN" and not a clean cut truck system

Are you asking for performance? If so, here is some info:

 

Express/Savana, Duramax 6.6L (LLY)

250 HP @ 3200 RPM

460 lb-ft @ 1600 RPM

 

Hydramatic 4 speed w/overdrive (MN8)

 

Essentially a derated version of the LLY Dmax (05 HD pickups were rated at 310 HP and 605 lb-ft of torque, respectively). From what I have researched, the Hydramatic is basically the 4-80LE with higher flow coolers. I would suspect this motor to be compairable to the old PS 7.3L diesel that Furd used to put in their trucks. Not a neck-breaker, but a good work horse.

Thanks for the quick response....I forwarded the info you left ont he post here. And did receive and answer back already from "Edge" ...here is what they say:

 

If that is in-fact correct, the EJC1000A should work on the van. You may ask the guys on the forum if any of them have used the juice/juicewam with success on the van.

 

Now I can only imagine how many vans with diesels and autos are out there...next to zip. So I really don't know who to ask....just hope that someone who owns one reads this post

Edge Juice wont work on a Express/Savanna Dmax. Dont try it!!!

 

the van 4L80e is almost the same as all other 4L80's..."different torque converter, hardend input shaft and strengthend planetaries"....thats info direct from the "GM trans god himself"

 

(its not me)

Yes...I have been finding that out, among other information. Like the transmission is a 4L85E-HD. Also they are coming out with a 4L90E-HD (6 speed) it is being tested now.

The Perform ace equipment is none...and there is not enough call for any research and testing for the public

if its a 6-speed I think it would be called a 6L90e

 

They already use the 6L80e in the 2007 Escalade and Denali. Eventually the 6L50e will go in the Tahoe's I think....

not really sure on numbers and vehicles...other than they are coming up and out with one for the diesel van.
