Repairs of all systems and mechanisms of your car starts with diagnostics. And automatic transmission is no exception. Timely diagnostics will save you from problems with major repairs and big financial costs, since it is much easier and cheaper to eliminate any malfunction at the initial stage. It is necessary to perform diagnostics for preventive purposes approximately once a year. But there are some situations when your iron horse itself gives you a hint that it would be great to visit a car service.

Cases when you shouldn’t put off the diagnostics:

• An indicator on the dashboard (if there is such) lights up or flashes informing of a malfunction;
• Jump-starts and bumps when changing gears, in such cases they also say "the gear box kicks";
• External noise and vibration;
• Monitor the oil condition, if it turned black and acquired a burning smell, do not delay, sign up for diagnostics immediately.
