I have a 1991 Toyota Camry, 4 cylinder, with a 5 speed transmission that will not go into gear when car is started. I can put the car in 1st gearwhen it is not running and when I turn the key while it is gear it will move forward. The clutch resevoir was empty of fluid and I refilled it, but it still does the same thing. I am assuming that the master cylinder is bad (leaks), but and not sure. I do not see any obvious leaks. I am capable of fixing the problem if I am sure of the problem. Any suggestions?
