need help identifying this r series transmission

[wideopenoutdoors]

i have the option to by this transmission but im not sure what it is. the hole in the bottom of the bell housing leads me to believe its a r151f, but it has a chain drive transfer case. any help would be appreciated.

I'm not 100% sure but maybe it's an r150 with an r151 bell housing to work behind a 22re

could some one have put a v6 chain drive transmission on the r151f? i understand the pre 95 r150 and r151f are very similair.

Is there a chance it's from out of the country?  I seem to remember the non-us "r151" had a chain drive case on it

Looks like regular v6. Didn't look like 22r bellhousing to me

I don't believe it is r151f. I say that due to the location of the tcase shifter. R151f is a fwd shift. That looks to be top shift. Does anyone else feel that way? I believe the newer r150 could be had with a top shift chain case but I am no r series expert.
