Dont like the fuel saving of overdrive anymore?


Since your trans is computer controlled you gonna have to deal with deleting it from the ecm

you should be able to use the original transfercase depending on the output shaft of the transmission as the mounting pattern is the same for the 4l60 and the th350, another cool thing about chevys is so much stuff is interchangeable.

but as neo said yeah your trans is computer controlled. i dont know how leaving all that stuff unhooked is going to effect your motor. it might just throw a check engine light or might not run all together. google around im sure its been done a hundred times or so. in fact i have one set aside also for when my 4l60 takes a dump

Curious...why would you put a TH350 in it? It would bolt in, but you would need another transfer case, or an aftermarket adapter. The ECM would need to be programmed to remove the 4L60E, a VSS installed in the transfer case if its changed, and the throttle linkage will need to be modified to accept the trans cable.

I'm sure I've missed some details, but it sound like a bit of a project to put a lesser transmission in. $.02

A TH350 isn't electronic, so it won't work with your computer. The ECU will need to be reprogrammed.
