I have this transmission. I thought it was a G54 because the guy I got it from said it was out of an 88. However after looking on Marlin Crawler, I don't think that it is. Of all the transmissions I have looked at, I have determined that I think it is actually an R150F. I say this because there are only a few transmissions that have the gear shifter on the tranny and the tcase shifter on the t-case. If you look in the photos the transfer case separates between the two shifters. I base the rest just on the molding lines of the transmission. The other notable thing is the little nub thing that is sticking up between the two shifters. I don't know what it is but I do not see that on any other transmissions. So can any body confirm my observations? I am trying to sell it but don't really know what it is to sell it.



This is a pick I found of another R150F

 

Maybe a w56b..

A pic of your trans cleaned up with our all the oil on it and a better side profile would help
The shifter base isn't raised up on your trans like a w59

 

W56 variety by that pic

:wabbit2:

 

You think it is multiple different W56 parts?
