I'm positive that it is a W-56, it has that little sensor on the side of it and the Bell housing is not any where near the same as an R series trans, plus like I said it has a top shift t-case, but it does have these cool red leather shift knobs that I will be taking as a fee for all the trouble this has been.
What I think happened is that they realized how cheap that they were giving a R-151 and t-case away for. When I called them a week ago they said that the "original" tranny they had was no good so they were going to find a different one. and give me that one. They probly thought I wouldn't be able to tell the difference. Boy were they wrong.
Going to go up to Denver this weekend and take the W-56 back and make sure that I get the R-151.
