Do you have a shift kits in it? The reason I ask is because some of a
700R4 stocks parts are not too stong and shift kits can strain then to failure (particularly the sprags). If hard shifts are your game, you should consider a 4L80 instead of repairing the 700R4. The 700R4 is not a bad tranny and used as designed will last a long time put when you start tweaking it you can sometimes shortens its life.
