I had the suspension work done on my automatic Cuore and gear oil was leaking in it, so according to the mechanic, there was a seal leak in the chamber, so the whole gearbox was removed and a new seal was installed, and 1 liter of additional gear oil was also included by the mechanic. Since then, there has been a problem with its gear shifting. The gears are not shifting on time as they have been shifting at very high RPM and before this mechanic's work, they were working smoothly.
