These can be identified outside the vehicle with the torque converter removed by a narrow front pump spline. Externally the switch pitch version has two electrical connections, where the non-switch pitch THM has only one. GM used a Switch Pitch torque converter in the Buick twin turbine Dynaflow transmission between — and the Super Turbine two speed transmissions used by Oldsmobile , Pontiac, and Buick divisions between The switch pitch is not the only THM that utilizes an external 2 prong connector. Other units to include the 2 prong connectors had an internal pressure switch that was used to control spark timing retard. It can be identified by ” THM” cast into the tailhousing.

Modern automatic transmissions go far beyond the old slushbox technology inside the typical TH or C4 you find in most hot rods.

With great power comes great responsibility…oh, wait, wrong story. Knowing that these guys have more overdrive gearboxes running around some seriously heavy-hitting powerplants, we knew these were the guys to hit up. Gearstar uses top-shelf components in their performance transmissions.

Because finding the pedals, Z-bar, and a decent new or rebuilt shifter and matching transmission would take a fair amount of both time and money. The auto conversion has some small advantages, such as the smooth shifting and fuel economy you’d get with the R4 overdrive. But the new or new-looking console and horseshoe shifter aren’t cheap.

One advantage the four speed would have is that they seem to add more value to a car than an automatic. Nothing is more fun than revving the engine at a light, or catching 3rd with that much power.

Maybe someone else here has a better estimate of the time and money for either or both?
