Maybe someone should explain the terms "forward shift" and "top shift". My '84 xtra cab 4x4 had what I assume is a G52. One day I saw a '87 R151F "turbo" transmission, with transfer case, for sale (for $400 <img src="/forums/images/graemlins/kewl.gif" alt="" />) and bought it without even thinking about compatibility issues. Fortunately it fit perfectly. In both set-ups the transmission shifter and t-case positions were the same. The t-case was shifted from the adapter housing, not from the top of the t-case. I believe that this is what is meant by "forward shift".

What about the transmission shifter positions across all the various five speeds in 1979 - 1995 Toyota 4x4s. Are they all roughly in the same position? G52, W56, R151? I might pull the R151 for a 4runner that I've got. If I rebuild the '84 I'd like to put a W56 into it. Is there a W56 that would go in without floorboard cutting? If so, from which model and year truck/4runner? -- Matt
