TCI BREAKAWAYÂ® CONVERTER, GM,
1965-91 TH350/400 With DUAL BOLT PATTERN
The first step into serious high performance, the Breakaway® is
a great torque converter for moderately modified street machines and weekend
racers also used as daily drivers. It provides approximately 2400 to 2600 RPM
flash stall without negatively affecting part throttle driving. Designed for
efficiency at highway cruising speeds and to launch hard at wide open throttle,
the Breakaway® is a fantastic all-around torque
Hardened pre-ground pump hub
Improved low end power
Bolt-in (no modifications required)
1,000+ RPM increase in stall over stock
Fits TH350/TH400 with dual bolt pattern (168-tooth
Important note from our company president, Skip White.
Low-grade torque converters are plentiful on the market and are priced far below the high quality units. Their general appearance may look identical to the high quality converters, but rest assured, the build quality is very poor. The performance is
noticeably poor and failure rates are high. True stall rates are not accurate. These converters often lined up poorly with the transmission spline. Strange noises were often a problem also, and this was indicative of failure soon to come.
If these low c
ost units were even close to being similar to the high cost units, we would sell them. As a matter of fact, in years past, we did sell them. It wasn't long before we realized they were not the product they claimed to be. The warranty on them from the manufacturer was also a problem. Over the years, we have dropped numerous non-branded products due to quality far below what is acceptable. I can't see any justification for ever running one of these low cost units in a car. You would be better off buying a high quality used converter and take your chances with it rather than one of those low-grade units. It is my strong recommendation that you invest in a high quality torque converter.
What is the difference in the terms
"Flash Stall" and "Foot-Brake Stall"?
Of the two measurements of stall, 'Flash Stall' is the most accurate.
Foot-Brake stall is dependent upon too many variables (i.e. type of braking system, disc or drum brakes,
how well adjusted the brake system is, ring and pinion ratios affect foot-brake
stall more dramatically, idle characteristics of engine, cam installation for
low end torque as needed by automatic transmission).
Flash Stall can be determined a couple of different ways:
1. With the vehicle sitting still and idling in low gear, apply full
throttle. As the vehicle begins its motion forward, notice the RPM hand on the
tachometer. That is your Flash Stall. (Engine
should be very responsive from idle. If not, camshaft timing and/or carburetor
adjustments may need to be made in order for engine to be crisp from idle.)
