Description
TCI Competition 112700: Overview
The TCI Competition Transmissions 112700 belongs to TCI Auto’s Competition transmission range, a product line designed for the demands of drag-racing competition.
This particular model is a remanufactured three-speed automatic transmission configured with a full-manual valve body and reverse shift pattern. Unlike a conventional automatic transmission designed to shift automatically during normal driving, the supplied product information states that TCI Competition transmissions retain no automatic shift features.
The 112700 uses a Mopar bellhousing bolt pattern, making this an important consideration for buyers evaluating engine and transmission compatibility. It has a 2.45 first gear ratio, a 24-spline input, and an 18.375-inch tailshaft with a slip-on yoke.
One of the defining features of this transmission is its trans-brake, which is included with the unit. This feature forms part of the transmission’s specialized drag-racing configuration.
TCI describes its Competition transmissions as being built with performance-oriented internal components, including high-performance clutches and bands, special heat-treated races and sprags, and improved lubrication.
TCI also states that these transmissions are blueprinted and modified for maximum performance before being dyno tested and pressure tested. These details distinguish the Competition line from a standard replacement automatic transmission.
The 112700 uses an OEM-style aluminum transmission case. It has a stock-style transmission pan and is not lockup compatible.
The transmission is sold individually and does not include a torque converter, flexplate, transmission controller, wiring harness, transmission cooler, transmission fluid, or dipstick.
Designed for Drag-Racing Competition
The TCI Competition Transmissions 112700 is specifically positioned within TCI’s Competition transmission range for drag-racing applications.
TCI states that Competition transmissions are designed to withstand the demands of drag-racing competition. The product line is available with full-manual and trans-brake configurations and does not retain automatic shift features.
For the 112700, the full-manual valve body and reverse shift pattern are central parts of its configuration. Buyers looking for a transmission intended to operate as a conventional automatic should therefore distinguish this model from standard automatic transmission products.
The included trans-brake is another important feature for the intended racing environment. Because the trans-brake is included as part of the supplied configuration, it should be considered when comparing this transmission with other TCI Competition models.
The 112700 has three gears and a 2.45 first gear ratio. Its 24-spline input and 18.375-inch tailshaft provide additional drivetrain specifications that should be checked against the intended application.
TCI identifies special heat-treated races and sprags, high-performance clutches and bands, and improved lubrication as features of its Competition transmissions. These components are designed around the demands of performance use.
Construction and Performance Features
The TCI Competition 112700 uses an OEM-style aluminum transmission case. The transmission case does not have a built-in transmission shield or flexplate shield.
The Competition transmission line incorporates several performance-oriented internal features. TCI identifies heat-treated races and sprags as well as high-performance clutches and bands within the range.
Improved lubrication is another stated feature. TCI also describes its process of blueprinting and modifying these transmissions for maximum performance, followed by dyno and pressure testing.
These manufacturing and testing details provide useful context for buyers evaluating the transmission as a specialized competition component.
The transmission uses a stock transmission pan and an aluminum case. It is not lockup compatible, and the supplied specifications do not identify a numerical horsepower rating for this specific model.
Because no numerical horsepower rating is provided in the supplied information, buyers should not assume a specific horsepower capacity beyond the product’s stated Competition application.
The transmission is remanufactured, so its condition classification should also be considered when comparing it with new or other remanufactured transmission options.
Why Choose the TCI 112700?
The TCI Competition Transmissions 112700 combines several features specifically associated with a competition-oriented transmission.
Its full-manual valve body eliminates automatic shift functionality according to the supplied TCI description, while the reverse shift pattern provides the specified shift configuration for this model.
The integrated trans-brake is one of the most significant differences between this transmission and many conventional automatic transmissions. Buyers specifically looking for a Competition transmission with a trans-brake can therefore consider this configuration.
The 112700 also incorporates the Competition line’s specified high-performance clutches and bands, heat-treated races and sprags, and improved lubrication.
Its three-speed design and 2.45 first gear ratio provide additional drivetrain characteristics that should be evaluated alongside the engine and rear-end configuration.
The Mopar bellhousing pattern, 24-spline input, 18.375-inch tailshaft, and slip-on yoke are equally important when determining physical compatibility.
Another important consideration is what is not included. The 112700 does not come with a torque converter, flexplate, transmission controller, wiring harness, transmission cooler, transmission fluid, or dipstick.
Who Is the 112700 Designed For?
The TCI Competition 112700 is primarily designed for buyers building or maintaining drag-racing vehicles that require a specialized full-manual transmission with a trans-brake.
Drag racers, performance vehicle builders, racing teams, and drivetrain specialists may consider this transmission when its Mopar bellhousing pattern and other specifications match their application.
The product is particularly relevant to buyers who specifically require a full-manual, non-automatic-shifting transmission. Its trans-brake configuration further positions it toward dedicated performance applications.
The 2.45 first gear ratio, 24-spline input, 18.375-inch tailshaft, and slip-on yoke should all be checked against the complete drivetrain before purchase.
This is not a general-purpose replacement transmission. Its Competition designation, full-manual valve body, trans-brake, and lack of automatic shift features make application-specific selection especially important.
Customers comparing other performance automatic transmissions can review related transmission options based on application, gear ratios, valve body configuration, bellhousing pattern, input spline count, and other drivetrain requirements.
