TCI Circlematic Transmissions 742020P1

This remanufactured two-speed is a clutchless design that holds low gear only, running a torque converter that comes included in the box rather than sourced separately, with a direct-drive flash stall and a full manual valve body on the Chevy bellhousing pattern. How it differs from a standard automatic Because it's clutchless and limited to one forward gear, it suits a narrower set of builds than a multi-speed automatic, typically where simplicity and direct-drive behavior matter more than having several ratios to shift through. Seventeen splines carry the input shaft, first gear sits at 1.82:1, and a steel clutch hub rides inside an OEM-style aluminum case finished natural. The tailshaft runs 11.250 inches, long by comparison with some other units in this catalog. What's already included Unlike several other remanufactured automatics in this catalog, this one ships with fluid and a dipstick already in the box, along with the torque converter itself, so there's less to source separately before it goes in. Output runs through a slip-on yoke, and the whole unit is remanufactured rather than built new. Each is sold individually and checked before it leaves the shop. Does this shift through multiple gears? No, it's a low-gear-only, clutchless unit by design, not a multi-speed automatic. Is a torque converter included? Yes, it comes with the transmission rather than needing to be bought separately.
