Disadvantages, breakdowns and problems of the Niva box
Most of the complaints come to the noisy operation of the manual transmission and its fuzzy switching
In second place are strong vibrations and howl of the box at certain engine speeds
Next come oil leaks from the seals, followed by switching difficulties
And the last is the spontaneous disengagement of the transmission due to wear of the latches.
