+2 on the used 700 shell and monster internals. Another reason to look at the newer trannys is an inherient flaw from the original overdrive. the original 700's allowed OD to come in in 3rd gear due to the pressure switch being placed in the appropriate port.At this point in Gm history the OD was added as a means to help cool the tranny better by routing more fluid through the tranny and cooler. It is a simple fix but if you buy a rebuilt one in these years it is likely that the pressure switch will be in the same OE port not to mention the other upgrades like a stronger pump.

This is all good news. I was going to trade my 93 700r
4 for an older unit. Not to thread jack, but my 93 700r4 doent have a tv cable only a plug connector on the right side( I may be wrong let me check again tonight) and the speedo is electric what can be done to make this work in carbureted trucks?

I am pretty sure all 700R4 have a TV cable.

Guess mine is a 92 ... is it worth rebuilding for overdrive? I have a turbo 350 in my truck now but wouldn't mind having overdrive, heard the 700r4's were a bit weaker though any truth to that? Running a slight 350 with a bit of work but nothing crazy, just daily driver useage.

700R4's are not weaker than a TH350.  With the right components they can handle more power than you can plant on the street.  The were factory rated at 450lb\ft and can be built to handle in excess of 650lb\ft.

I would drive on down to monster trans and pick one up that what I did ended up with a hd build 450hp/tq rated for a few dollars more you can get the monster build no core needed and I ended up with a k case tranny. picking it up yourself saves you a little bit as well.
