Toyota Transfercase Question

[JDaniel85]

I have a 1993 Toyota 4Runner. 3.0 V6, R150 transmission, stock chain drive TCase. Scored a geardrive 4.7 single case with the adapter for the transmission. Does anyone have any first hand experience as to whether or not I will have to modify my cross member? I want to have all my ducks in a row to make this as smooth a swap as possible.

Not sure abt the cross member. No mention of it in this.

This link mentions a few other hiccups but says to use 79-90 4cyl tcase Mount with v6 cross member.

I bet you need a new cross member. Trail gear will probably have a part number for it.

I actually just went and got a crossmember today. I will need to modify it to mount up but I should be good to go now thanks guys

Ok so I just finished installing the 4.7 gear drive case today. It was a pretty simple but tedious fix for the crossmember. The mounting holes for the TCase itself were the same and even used my old bolts from the chain drive case. All I had to do was move the mounting tabs back around 7/8” and weld them in. One side had to be extended upward as the mounting holes were farther up the case. Pretty simple just took a little time to get it just right. Pretty clean swap altogether and now I have some super low gearing in low range.
