Them other folks is right. The bellhousing will bolt right up. What might not be so easy are the torque converter (may have to adapt the flexplate and use a switch/kit if you wanna use the locking TC, the rear crossmember and the driveshaft length (the TH700 is 3 inches longer than a Glide or TH350.)
You'll also need some provision for a TV (throttle valve) cable, since the tranny won't work without one. It's a whole different ballgame from a TH350 detent cable that's only needed for kickdown shifting...it has to be there and properly adjusted for shifting to take place.
Again, if you want to use the locking torque converter, there are numerous ways of approaching it. I think the easiest (other than not connecting it at all) is to wire it so that it automatically engages when the tranny shifts into 4th (OD.) There's a
diagram that shows how to do it on a TH200-4R on my
web site\'s links page. The TH700 and TH200-4R are real close in their use of the TCC solenoid, so this could be adapted real easily. It's a heck of a lot cheaper than the Painless kit that sells for around $150 for a vacuum switch and some wires.
The other option you might wanna choose is the TH200-4R. It's also a 4-speed with overdrive, but the gear ratios are a lot more evenly spaced. The bellhousing patterns are the same and the length is the same as the TH350/Glide. You'd still need the TV cable, since both trannys use it in the same way...as is the case with the locking TC.
Good luck with it,
But, lots of good info. I already have a rebuilt 700R4, everything 'beafed up' I was going to put it behind a 350 with about 425 HP running Nitros in my other 46 1.5 Ton, but I may have to look into the 200 for this project.
