Disadvantages, breakdowns and problems of automatic transmission 6F55
This is a completely reliable machine, but it is installed only with especially powerful turbo engines.
And for overly active owners, the GTF lock friction wears out quickly
This dirt then clogs the solenoid block, resulting in a decrease in lubricant pressure.
The pressure drop turns into a quick wear of the bushings, and sometimes the oil pump
Typical for this series of gearboxes, the problem with the disruption of the stopper is almost never found here.
