8v92 with a six speed Allison

[buswarrior]

Luvrbus,  I'm a little unclear on the rear end gear sets.  Are they standard heavy truck parts or do they have specific models for "pusher" axles?  Also, what am I missing with ddecII that the III gives me?

regards,

A rear engine coach axle is "rolled over" compared to a front engine truck. Right and left tires are the same, differential is rolled upside down, facing rearward.

Before overdrive transmissions appeared, committed busnuts did research on axles suitable to flip, in order to get taller gears, to go with hot-rod engines, for more speed and/or economy.

The regular coach axles didn't go taller than 3.33, not much better than the typical 3.7.
An 8V92T, HT740 and around 2.5 diff was a real cruiser. Fly when you wanted, sip fuel when you don't.

Happy coaching!

The DDECll will not interface with the World Transmission has the wrong protocall it is a lot easier and cheaper to up grade the 8v92 to the DDEC iv BTDT to many times,that is why they came with 741 or 755 ATEC
