The transmission doesn't have to come out to install the valve, but it has to be pushed back some and the torque converter removed to access the check ball/capsule in the front of the input shaft.
He may have just been confused, as a lot of units are set-up so that the TCC doesn't apply until the transmission makes the shift into OD. This is usually accomplished by wiring the TCC solenoid through or grounding it with a normally "open" 4th gear pressure switch.
I've tried using a TCC for retrofits into older cars, and like the non L/U deal a LOT better. A high quality torque converter with efficient characteristics is required, but the whole deal makes using OD's in older vehicles much easier......Cliff
