  A:

  One can suggest that problems can decide in terms of shift reaction, including jerkiness, no engagement, or the inability to downshift during hard acceleration. The possible causes of erratic shifting are many but the main solutions include; checking the transmission fluid levels and modify as required, using the right fluid. Check the condition of the fluid; if the fluid is dark, gives an impression of contamination, or has a burning smell, replace the fluid and the filter with the recommended standard since a burning smell may indicate internal slippage and possible future repairs. Check the installation of the transmission filter and arrive at the condition of the gasket; tighten any loose gasket, pressure line and fitting. Further, look for the signs of shift linkage or throttle linkage and vacuum hoses for the break or looseness. If the transmission does not shift correctly check the shift linkage for proper condition as well as adjusting it and check the fluid level in the transmission if it is low add more. If the linkage is correctly installed and the fluid levels are good still the engagement fails there may be internal damage needing the component to be removed and disassembled. For downshifting problems during powerful acceleration, look for non-functioning sensors or control units in vehicles with computer-controlled transmissions or go for correct setting of the kick down linkages or vacuum servos in other automobiles. We should always check that the electrical connectors in systems employing ECMs are correctly connected, clean and are not damaged in anyway and that the cleaners used in electrical contacts do not cause more harm.
