And Last But Not Least I Plan On Rebuilding The Transmission A.s.a.p Before It Leaves Me Stranded Somewhere I Have A 350 With A Couple Mode Headers Intake 4 Barrel Cam.....etc N Was Wondering What Torque Converter Would Be Good For The 700 Trans I Use The Car On A Daily Basis For Now But I'm Trying To Have It Street Performance Nothing Drastic Like To Take It To The Strip Or Nothing Like That I Plan On Putting A Shift Kit On The Trans Bit I'm Not Sure What Would Be My Best Option With The Torque Converter N Would Like Some Opinions Or What Would Be My Best Option...thanks

Soft shifts after the Trans get warm/hot is a sign of low pressure. Worn seals, too much clearance in the Pump etc..
A pressure test would help show what's going on in the Trans.

The best Stall for the TC would depend on the Cam and rear gear ratio.

700R4's don't use a Vacuum Modulator, so it doesn' need a Line from the Engine. It uses a TV/ThrottleValve cable which controls, line pressure, shift points, shift feel, part throttle downshifts and the detent downshifts.

Have you checked the TV cable adjustment?

If you're using an Aftermarket Carb it will also need a TV geometry corrector bracket.

XE274H >> http://www.compcams.com/Company/CC/c...x?csid=87&sb=0 2200rpm stall recommended, so 2200-2500rpm stall would work well.

Price will depend on the Brand and if you use an (off the shelf) or custom TC.
For a mild Combo these should work fine. Good quality & very reasonably priced. Right row, 4th down.
