How do I change the manual transmission fluid on my 1.6L 5 Speed 2001 Accent? I have 113,000 miles on my car and have never changed it. From reading various posts I probably should have changed it a couple of times already since I drive 35 miles each way to work and about 10 miles of it is stop and go traffic. I've recently started having problems with shifting. I have to wait at least 2 seconds before shifting, or wait until the RPM's drop below 1500 to shift, otherwise they grind a little bit as if I didn't push the clutch in all the way. I tried bleeding the clutch and replacing the clutch release cylinder, but no luck. I'm hoping changing the oil will fix the problem. It's about $115 for the clutch master cylinder. If the repair is going to involve dropping transmission, then I'm out of luck.
