Hi group, I am very novice about car and few months back I bought a 93 Honda CIVIC LX Sedan. Last time I took for oil change, mechanic told me to change transmission fluid. I checked by myself using dipstick. Color looks brown, and it is touching only the very end of the stick, what I thought that fluid level is very low. I dont know when it is changed last. I am having another problem what might or might not related to this. My odometer gauge is getting stop at 0 once in a while. The engine check light coming out after driving couple of miles each time. Now my question to you, 1) Can you instruct me, how can I change transmission fluid by myslef.Whats the step involved? Do I need to lift my car up to do this? Mechanic is asking me for , but I am not willing to pay this, if I can do myslef by buyin transmission fluid from store.I have a friend who works as a mehanic, will do it for me by , but he never did this. He told me if I can rely on him, he has all tools do this. Is this risky to do from a beginer. Can this ruin my transmission. Please advice, with steps to do this.I would appreciatey your help. 2) Can this low/dirty transmission fluid cause my odometer to malfuntion? What is happening is, it is working for a while, then it is getting stuck at 0. It started working again suddenly.Sometime, it is fluctuating rapidly from 0 to the speed.Engine check light coming out. Any idea, whats going on?? Should I take care of it ASAP. I am not in a condition to spend extra money for fixing this car for those cause because of my affordability. Thanks,
