Remanufactured Allison Transmission М6620 S6620 H6620 H6620A

Model M6620
They are used to drive the chassis of off-road vehicles (mining dump trucks, mobile drilling rigs, etc.)
It has an electronic control system with a large selection of settings (including manual gear selection and control from a remote control), thereby ensuring the best interaction between the operator and the machine equipment.
The self-diagnostic function assists the operator in troubleshooting transmission problems, facilitating troubleshooting, thereby reducing downtime.
Possibility of equipping with a transfer box, ensuring the transfer of 100% of the power flow both to the upper equipment and to the vehicle chassis (to the front or rear drive axles). The chassis drive is mechanically disengageable, which makes these transmissions ideal for mobile drilling rigs, as well as mobile platforms with various equipment.
Possibility to install up to 2 PTOs (power take-off box). PTO control can be either manual or electronic, providing timely switching on and off, which makes working with them easier and safer.
The use of a torque converter operation control system in automotive technology avoids wheel slip and provides high vehicle cross-country ability
The option of a built-in hydraulic retarder provides reliable deceleration of the vehicle without additional load on the working brake system, which significantly extends the life of the brake mechanisms and increases safety, especially in mountainous areas and quarries.
It has 6 forward gears and 2 reverse gears, with two gear ratios.
