The TCI Breakaway 240900 is an 11 in non-lock-up torque converter for GM TH350 and TH400 dual-pattern applications. It uses furnace-brazed fins, needle bearings, a hardened pre-ground pump hub, computer balancing, and a dual bolt pattern.

This converter is aimed at moderately modified street machines and weekend racers that still see daily-driver use. It provides a 2200 to 2400 RPM stall range and is built to improve low-end power and acceleration without requiring vehicle modifications.

TCI notes that the Breakaway is a bolt-in converter with no modifications required. This version does not include an anti-ballooning plate; TCI points to 240901 for the heavy-duty anti-balloon plate version.

The TCI StreetFighter 241001 is a 10 in non-lock-up torque converter for GM TH350 and TH400 transmissions. It uses furnace-brazed fins, needle bearings, a hardened pre-ground pump hub, dual bolt pattern, and an anti-ballooning plate.

This converter is built for street-strip combinations that need a higher RPM launch and stronger low to mid-range response. TCI lists a 3000 to 3400 RPM stall range and notes up to a 1500 RPM increase in stall over stock.

The anti-ballooning plate supports harder use in more aggressive combinations, while the dual bolt pattern helps cover TH350 and TH400 applications. TCI recommends confirming vehicle weight, engine displacement, power adders, rear gear ratio, and tire diameter for accurate stall matching.
