If it where mine, I would forget about both transmissions and go with a NV4500 5 speed manual. However, if you do go with a 700R4, make sure to get an 87 or newer. My 82 Suburban 6.2 ate through several 700R4's in short order until I went with an 89 700R4. And even then, it had to be tweaked several times in order for the torque converter to hold in 4th gear. The 6.2 had enough torque to cause the torque converter to slip in 4th gear.

In my 1990 Suburban, I went with a manual transmission and couldn't be happier.
