I have a 2001 Honda Accord, every time the car shift up the car is like chought or jerk, this mostly happen when the transmission shift from 1 to 2, I was try to chang ethe transmission fluid but I couldn't find the cap to put the fluid in and I also can't find the transmission filter under the car.

I have an other question is when I climb under my car I found the nut that let the transmission fluid goes out but I can't find the key for it, I went to Pep-Boy, Home-Depot and other car store, all they have the Hex Key, but my is not that, my is like a Square socke head cap.

Is anyone have any idead what happen to my car and how to change my transmission fluid ? Thank You

 

Your transmission should be under an extended warranty so take it to honda and tell them what it is doing. Also just stick the socket wrench without a socket onto that nut/screw. Its 3/8 size just use a 3/8 wrench.
