A new, larger transmission and transfer case was also part of the upgrade.
There are two different types of "internal workings" found in most transfer cases.
There was no low range in the transfer case.
In addition, 4-wheel drive was added via a 2-speed transfer case.
The suburban runs great because the engine, transmission, and transfer case were all new.
There were a total of 5 transfer cases for the four-wheel-drive Ram.
And I appreciated the easier shifting of the new transfer case.
The low-range transfer case found in the previous generation has been removed.
At least two drive shafts were used, one from the transfer case to each axle.
Thus, some modification on the transfer case or the adapter is required.
