My mechanic convinced me to do a full transmission service on my Corolla 2001 with 80K miles. I know some places flush transmission under pressure with special machine which is much better then just drain and replace transmission fluid. My mechanic does not have this machine, however he charged me $110 for changing transmission fluid, gasket and filter. I called other shops that have this special machine and they quote at least $175 for fluid, gasket and filter. My first question is if it is really necessary or highly desirable to flush transmission with specialized machine vs. just draining and replacing fluid. Second question is if replacing gasket and filter is also necessary. Finally last question is how often I need to replace transmission fluid and how often I also need to replace filter and gasket. Is there anything else in transmission service that I also need to do?
