Review
The MT82 manual transmission has six forward gears and a reverse gear. It is installed along the longitudinal axis of the car, and its maximum torque is 360 Nm. The cast aluminum gearbox housing is bolted to the transfer case via a cast aluminum extension.
The 6th gear ratio has been chosen to improve economy and comfort during fast driving. Optimal gear shifting ensures economical fuel consumption and efficient use of engine torque. Six-speed transmission provides a wide range of gear selection for improved economy and controllability (e.g. when maneuvering at low speed or when towing a trailer).
Name "MT82" reflects the distance between the two shafts in the gearbox:
- M - mechanical
- T - gearbox
- 82 - distance between two shafts in mm
The transmission is refueled for life and a service level check is not required unless a leak is found.

Rating plate on the right side of the gearbox in the area of the output flange for attaching the cardan shaft.
It is for the sole purpose of identifying the transmission. All orders for spare parts are subsequently carried out using the vehicle identification number (VIN).

The input shaft is movably connected to the output shaft through a guide bearing (3). To absorb axial forces input shaft ball bearing (7) has additional protection.
All input shaft components can be serviced individually.

The intermediate shaft transmits torque from the input shaft to the secondary. The drive and driven gears are located on the shaft, as well as the 3rd/4th gear synchronizer clutch. Gear wheels of 1st and 2nd gears and reverse gears are non-removable.
The countershaft drive and driven gears can be replaced separately. Improved manufacturing tolerances eliminate the need to replace pairs of gears.
The intermediate shaft is solid. To prevent axial movement of the shaft, it is additionally fixed with a bolt (1) and bearing retainer plate (3).
The direction of rotation of the output shaft is changed by means of the intermediate gear of the reverse gear (21).

The rotation of the output shaft is transmitted through the output flange to an extension shaft connected to the transfer case. The 1st, 2nd and 6th gears, as well as the reverse gear, are located on the output shaft. The gears of the 3rd and 4th gears on the secondary shaft are non-removable.
By analogy with the input shaft, the 6th gear drive gear has a mounted synchronizer ring gear (4). It provides torque transmission when the 6th gear is engaged.
The output shaft drive and driven gears can be replaced separately.
Triple synchronizer assembly

| 6 | - | Cone surface |
The synchronizer assembly has three friction surfaces. Due to the additional conical surface (6) the total friction surface with triple synchronization increases significantly. This allows you to reduce the required shift effort into 1st and 2nd gear.
Since the tapered surface is part of the drive gear, no additional synchronizer ring is required.

With the help of an intermediate reverse gear, a change in the direction of rotation of the output shaft is ensured. The reverse idler gear is fitted with a needle roller bearing mounted on the idler gear shaft. The axle is mounted in the support bracket (1) and reciprocal hole of the gearbox housing.
To absorb radial forces, the reverse idler gear is additionally located on the support bracket.
If the reverse gear can be replaced separately.
