A Body Stalling at Idle

I don't know where your from, but around here, that would be a good price for a tranny replacement and torque converter.
Try and shop for a tranny here; http://www.tciauto.com/
I think MoPar has a low stall performance converter for about $200.

TCI® Street Rodder™ Transmission Packages

Perfect for a mild daily driver or a Street Rod. Equipped with a TCI® automatic valve body with a Valve Body Improver Kit, it allows you to achieve a firmer, yet not too harsh shift in the vehicle and remains fully automatic. Retains the stock shift pattern. For the system to operate properly, all throttle linkage, vacuum lines and kick-down components must be connected.

Each TCI® transmission package consists of a triple-tested TCI® transmission and precision tuned TCI® torque converter. In addition, we also include a universal transmission cooler and three gallons of premium TCI® RTF transmission fluid.
