A toyota trans (have the code somewhere) or the colorado trans will work. The BH from the colorado must be used. The lack of a rear sump pan means fabrication, fabrication, fabrication. I estimate that it will cost $3500 minimum to get a 4200 done without having a dealers license to get the good auction prices. (based off of actual salvage yard quotes)
Engine w/ harness, pcm, accessories, etc. $1300
Colorado Transmission $700
Flywheel $300
ECM remapping for 5-wire hookup $400
Colorado oil pan to sacrifice $150
Gasket set $125
Custom header $100 (plus a few hours of welding)
Misc. $200
Shipping and freight $400
Vanity cover (optional) to make the engine look cool $200
Revised custom intake so it looks cool (optional) $200
as compared to a complete takout 6 liter with trans for $2200.
Financially the 4200 does not look good from the get go.
I am in the process of building a hybrid T-5 as I will use one in the truck and I need one for my Northstar powered Opel project.
