So just recently within about 5 days, iv noticed that while going through the gears that im getting some resistance while going into 2nd, 3rd, and 4th. Iv been driving this car almost everyday for almost a year and a half now and its always been very smooth and easy to put it into gear. Now its almost like im getting locked out sometimes and the shifter just feels really stiff and rough going through the patterns. I have checked my clutch cable and its fine. Does it sound like its time for a drain and re-fill on the trans?
