Product Overview
Many aftermarket truck torque converters match the casing but fail quickly under heavy haul loads. Shudder, climbing transmission temperatures and lock-up slip trigger unplanned downtime that derails your fleet schedules.
Built for heavy-duty transmission replacement, this unit delivers stable lock-up and controlled heat buildup during hill climbs and frequent stop-start cycles. Each batch is verified against OEM pressure profiles, not just outer dimensions.

Manufacturing Process & Quality Control
Every truck torque converter starts with raw material sampling to rule out flawed castings under heavy load.
Critical components run CNC precision machining to hold tight tolerances and keep fit consistent across batches.
Every finished unit undergoes hydraulic pressure testing to catch hidden leaks before delivery to your workshop.
Dynamic balance inspection reduces harmful vibration that would otherwise wear transmission bearings prematurely.
Full test records are securely stored, offering complete traceability for your internal fleet quality audits.
Application Scenarios & Product Value
Regional Highway Haulage
It handles repeated uphill pulls and long highway runs, resisting lock-up slip and heat build-up that cut short converter life for your on-road fleets.
Municipal Heavy Vehicles
For waste trucks and service fleets with irregular duty cycles, it reduces unplanned breakdowns that disrupt fixed public service schedules.
Construction Site Trucks
Frequent stop-start cycles and uneven heavy loads are common here. This unit maintains steady performance amid rough, unpredictable site operating conditions.

FAQ
Q: Will this unit bolt straight onto my existing transmission?
A: It fits the matched transmission housing directly. Just double-check your OEM part number to avoid fit issues.
Q: What happens if the unit keeps slipping under heavy hauling?
A: Persistent slip builds excess heat, which quickly ruins your transmission fluid and internal clutch parts.
Q: Does your warranty cover lockup failure on the truck torque converter under regular haul work?
A: We cover factory defects of the lockup assembly. Damage from wrong fluid or overloading won't be included.
Q: What oil type works best with this assembly?
A: Stick to the specified transmission fluid. Wrong fluid leads to rough lockup and shorter service life.
Q: How do you secure this heavy assembly for ocean shipping?
A: We wrap it tightly and fix it on a sturdy pallet to stop knocks and moisture damage during transit.
