Well, after 218K miles, the last 20K of which have been on 37's, my 700R finally died. I was just driving down the road at ~50 mph when all of a sudden my motor red-lined and I lost power to the ground. Pulled over, all looked good, but when I pulled back on the road I had to rev up to ~4500RPM just to get moving, the same thing in all gears. Since it had 218K on it and I was 2 miles from home, I said to he** with it and drove it home like that, slipping the whole way home. So here's my question, should I put another 700R back in or find a TH400? I have found a military TH400, adapter, 208, converter, and front driveshaft for $400 5 miles from my house. Is this an easy swap? Is it a good deal? I don't care about overdrive anymore, haven't used it much since the boggers anyway. Can I make my stock column shifter work? Is a TH400 the same length as a 700R? What is a TH400's 1st gear ratio? Thanks in advance. Oh yeah, as of now it has a 305, 700R4, 208, 60/14FF, 6 inch lift, and stock length driveshafts (the front has some slop in the slip joint also). Truck is a short bed.
