Model / Part Number: Allison 30845
Category: Fully Automatic Transmission

Product Overview

The Allison 30845 Transmission is a proven heavy-duty automatic transmission engineered for demanding industrial, construction, and off-highway applications. At Industrial Reman, we specialize in restoring these critical drivetrain components to OEM-level performance and reliability through a comprehensive remanufacturing process.

Each 30845 transmission is completely remanufactured to factory specifications—providing operators with the same power, shift quality, and endurance as a new Allison unit, but at a fraction of the cost.

Function and Application

Designed for high-torque, high-load environments, the Allison 30845 provides smooth, efficient power delivery across multiple gear ranges. Its hydrodynamic torque converter and precision gear design allow for seamless operation, reduced drivetrain stress, and exceptional durability under continuous heavy use.

This transmission is commonly found in:

• Off-highway haul trucks

• Heavy construction machinery

• Mining and material-handling vehicles

• Industrial transport and specialty applications

Remanufacturing Process

Our remanufacturing process for the Allison 30845 ensures precision, consistency, and long-term reliability through these key steps:

1. Complete Disassembly & Cleaning

   • Every transmission is fully dismantled and cleaned using advanced methods such as ultrasonic washing and media blasting to remove contaminants and residue.

2. Inspection & Measurement

   • All internal components—gears, shafts, clutch packs, and housings—are inspected to verify dimensional accuracy and structural integrity.

3. Replacement of Wear Components

   • All seals, gaskets, clutches, bushings, and bearings are replaced with new, OEM-grade components.

   • Torque converters are rebuilt or replaced, and valve bodies are calibrated to Allison standards.

4. Reassembly & Testing

   • The transmission is reassembled using precise torque settings and factory alignment tools.

   • Each unit is dynamometer-tested under load to confirm pressure balance, shift timing, gear engagement, and leak-free operation.

5. Final Quality Control

   • Every remanufactured 30845 undergoes a final inspection and performance certification, ensuring full compliance with OEM performance benchmarks.

Key Features

• 100% replacement of seals, gaskets, bearings, and clutch packs
