What transmission will work on a 94' LT1 corvette engine and an np231 transfer case? Thanks.

Thanks,will the nv4500 from a 89-90 chevy 4x4 bolt up to both?
I'm looking in the paper and for less than putting in a brand new nv4500 I can get an LT1 engine and a used nv4500. I'm just trying to make sure I'm not wasting my money and I don't know a lot about the compatability of these things.

Okay, so this guy is on crack. My nv4500 book from AA says they didn't even make nv4500's until 1993. I'm going to go insane if I don't get my Jeep back on the road soon. It's been two months since I drove it.

a 4L60E or 4L80E 4 speed autos will work too. they are in late model chevys. the 700r4 and the 4L60E both have a 1st gear of 3.06 plus the advantage of over drive. the 4L80E the the overdrive version of the th400 which means it is a heavy duty tranny. the 4L80E has a first gear ratio of 2.48. of coarse you can use either the th350 or the th400 which are autos with no overdrive. the sm465 and the sm420 are both granny low 4speeds and either would bee good for the swap if you choose a manual. what tranny did the lt1 have behind it? it was a 700r4 or 4L60E if it was an auto. i can't remember when they changed from the 700r4 to the 4L60E. anyway i hope this helps.
