EDIT 6/30/05: I have successfully installed a BW4406 from a Ford Expedition. Pictures of the install begin on page 8 of the thread.
Pages 1 - 7 are research for the swap.
-----------------------------------------------------------------------------
-----------------------------------------------------------------------------
OK. I want to really nail this down. I would like to get 4low in my V8 Mountaineer, with 6bolt, 31spline 4R70W.
I DON'T NEED AN ATLAS!!
Since this is the same transmission pattern that is used in the fullsized trucks such as the Bronco and F150 a t-case should be able to be found that mates up. What t-cases were used?
The real problem will be fitting? I know the older F150s and Broncos used the BW1356, and the BW1345 in manual versions. Does anyone have the demensions? What about the newer 4406 T-case from the expedition?
As used behind the full size Bronco:
NP208, Part time, chain, 2.61:1, 80-86
BW1345, Part time, chain, 2.72:1, 80-88
BW1356, Part time, chain, 2.69:1, 87-96
As used behind the F150:
BW4406 (Electronic, Electronic w/control-trac clutch, Manual)
BW1356 (Electronic, Manual)
BW1345 (Manual)
NP208 (Manual)
NP205 (Manual)
What about other creative solutions?
I'm looking for cheap cost as well as simplicity. Wiring is no problem if the t-case is electric. Fabbing a shifter shouldn't be too hard. I don't want to go the route of putting in an expensive advanced adaptors conversion and using a 1354 or 4405 control trac. That's over 500 for the adapter, and at least 150 to get the tailshaft installed in the tranny. There has to be a better way!
I'm posting this for two reasons: 1) I realy want 4low. I don't need AWD. 2) My front driveshaft took a crap, transfer case is acting weird. Rather than replace, I'd like to replace that stupid CV joint and AWD t-case.
To make things more complicated, my 97 has the VSS in the t-case tailshaft
