Let the conversion begin

The Allison cross member has roughly a 2" raised section where the tranny mount bolts. I'll take a pic of mine tomorrow.
Different vantage points obviously but you can see the raised section on mine. Pretty sure I can just cut that off and bolt right to the flat part of the cross member.
It is a done deal though, even got the interior all done too! I have some fine tuning to do with the tunes still but it's a lot better. I need to also experiment with a disabling codes because I have an engine light from the tranny being unplugged. At least till I get my wiring done and find a zf o.s.
Figured I'd post up these part numbers to help anyone looking to do the swap.
Shift lever with knob-15179181
Boot-15711228
Retainer-15711231
Insulator-15038077
Pedal to master cylinder pushrod bushing-12473050
All of these should be valid gm numbers and any dealer should be able to order them.
I used Dorman master and slave cylinders from Rockauto
Transfer case gasket is Dorman as well. P/N 917562
I don't have a part number for the clutch pedal assembly. But they are on ebay, just be sure you buy the 6 speed one and not the nv4500 5 speed one.
All nuts and bolts can be reused.
The exhaust pipe hanger that bolts to the automatic will have to be modified or not used
The fuel line brackets also will need to be modified
Transfer case linkage will need to be adjusted slightly to get full engagement of 4hi
Driveshafts can be reused, so far the aluminum rear is holding up fine.
Will post up the wiring end of it soon. I will be adding a clutch pedal position switch and pins to the ecm to have cruise, speedometer, and 4x4 without the TCM.

Modified my cross member yesterday. No more contact with the dash in 4th and 6th. I just cut the raised area off and welded a piece of plate in its place. Looks factory now :thumb:
