Chris, you have a couple of options. You can get an after market over drive
such as a gear vendors unit. Or replace the th400 with another GM over drive

tranny such as the 700r4 or 4l80e. the 700r4 is a lighter unit and I
personally don't think they are up to the task in anything but a 1/2 2wd
truck or car. if you went with one of those you would have to change the
transfer case to along with it. The 4l80 is basically a 4 speed
electronically controlled th400. you can reuse the transfer case but you
need to buy the transmission and tranny controller for it to work. With any
of the 3 you will have to have new drive shafts made or your existing ones
altered. I personally went with a 4l80, and kept the costs down by buying
all the parts I needed on eBay and the local salvage yard. the Gear vendors
are neat because you basically can overdrive all your gears making it a 6
speed. If you have access to a machine shop or have a buddy that does I have

seen Volvo over drive units used you just need to fab up the adaptor. If you

have any questions let me know.
