Disadvantages, breakdowns and problems of automatic transmission 3L30
First of all, this is a very old box and its main problem is the lack of spare parts.
It is also quite difficult to find a donor on the secondary, since there is nothing to choose from
And so it is a very reliable and unpretentious machine with a resource of more than 300 thousand km
The standard heat exchanger is rather weak here and it is better to install an additional radiator
After 250 thousand km, vibrations are often encountered due to wear of the oil pump bushings.
