TO-CR94 A518 46RE Torque Converter
The TO-CR94 is designed for 1996 and newer vehicles with the A518/46RE family. It features a 90-degree bolt pattern, four mounting pads, and a 23-spline input. It’s positioned as an OEM-stock stall option with lockup capability to optimize highway fuel efficiency and transmission heat management.
Key details: 90-degree bolt pattern, 4-pad mount, 23 splines, lockup function. This converter aims to maintain stock drivability while offering reliable lockup engagement for towing and normal street use.
TRANS_ONE TO-890HS 2400-2800 Stall
Designed for the A518/46RE family, this converter targets a higher stall range of 2400-2800 RPM, which can improve throttle response and acceleration in towing or performance driving. It uses a 90-degree bolt pattern with a 4-pad mount, and a 23-spline input for compatibility with typical Dodge transmissions.
Considerations include stall height versus driveability, potential towing needs, and the impact on engine torque curves. This option suits builds seeking quicker lockup engagement without sacrificing daily drivability.
MB-890 A518 46RE Torque Converter
The MB-890 converter targets a 2300-2700 stall range for 1996 and up vehicles within the A518/46RE family. It features a 11-inch diameter with a 4-pad mount and a 10-inch bolt circle, designed for lockup operation and durable performance under typical highway and light towing scenarios.
Engineers should weigh stall choice against camshaft, rear gear ratio, and overall torque output to ensure smooth lockup and consistent shifts during gear changes and acceleration.
47RE, 47RH, 48RE, A618 Single Clutch Billet Converter
This billet converter targets a range compatible with Dodge diesel applications including 46RE variants. It emphasizes single-clutch billet construction for improved reliability under higher torque, with lockup functionality to optimize highway cruising efficiency.
Key considerations include compatibility with diesel builds, lockup performance, and the balance between stall speed and torque handling to avoid shudder or slip at light throttle openings.
B&M 20400 Tork Master 2000 Torque Converter
The B&M 20400 Tork Master is positioned as a value-priced upgrade for mild performance improvements. It offers a 1900-2100 RPM stall range, intended for daily driving with stronger launch potential and improved torque handling without dramatic shifts in street manners.
When selecting this converter, assess engine torque, gearing, and transmission cooling to maintain reliability under extended highway and towing use. It serves as an affordable option for street rods and daily drivers seeking a firmer launch.”,
GM92SS1-4L60E 4L65E Torque Converter
Note: This option is listed for 4L60E/4L65E families and LS1 engines. While not a direct 46RE product, it is included here for readers pursuing broad torque converter knowledge across similar GM and Mopar torque converter generations and lockup principles.
Consider this section for comparison purposes, particularly when mixing components within multi-transmission builds or cross-brand projects. Always verify compatibility with your specific model year and engine size.
Buying decisions for 46RE torque converters hinge on stall speed, lockup behavior, mounting compatibility, and overall drivability. The right choice balances launch performance with highway efficiency, engine torque availability, and cooling capacity to prevent overheating during heavy use.
Buying Guide
Key purchase considerations
- Stall speed and drivability: Higher stall speeds boost off-the-line response but can create harsh feel at low speeds. Match stall to your engine torque and use case (daily driving vs. towing or performance).
- Lockup and efficiency: A reliable lockup mechanism reduces parasitic losses in mid-to-high speeds and helps stabilize engine RPM in cruising ranges.
- Compatibility: Confirm the bolt pattern, input spline count, and mounting pads (4-pad, 90-degree pattern) exactly match your 46RE/A518 transmission and vehicle configuration.
- Durability and construction: Billet or reinforced components improve torque capacity and longevity for heavier loads or aggressive driving. Consider heat management in towing applications.
- OEM vs aftermarket balance: OEM-stock options offer familiar drivability; aftermarket options can improve performance but may require tuning or gear changes to keep shifts smooth.
- Application scope: Some converters are designed for 46RE only, while others cover broader 4x family transmissions (A518, A618, 4L60E/4L65E). Ensure exact fitment for your setup.
Comparison at a glance
- Stock-stall OEM options: Emphasize reliability and fuel economy with smooth lockup managed to maintain normal cruising.
- Moderate performance upgrades: Stall ranges around 2300-2700 RPM provide quicker throttle response without sacrificing daily comfort.
- High-stall competition: 2400-2800 RPM options can significantly improve launch for towing or hot-street builds but may impact low-speed manners.
- Diesel-focused variants: Some converters target heavy torque and single-clutch designs for engines with high torque outputs, trading some quietness for strength.
All options should be evaluated alongside related drivetrain components, including transmission cooler capacity, gearing in the rear axle, and camshaft/turbo/supercharger configurations. When in doubt, consult a transmission specialist to select a converter that aligns with your vehicle’s power curve and intended use.
