Hi,
I drive a Honda Accord 03 but recently, i noticed the gear malfunction by not selecting properly. Mostly if i put on A/C in traffick, it will engage but forcefully transmit with high jack to next. (2) Is there other ATF to service this accord transmission apart from ATF DW1?
Thanks

BTT:
It is a 2000 Infiniti G20 (Nissan Primera, if you like).

The gear does not pick once I engage the gear in D after a long cold-time, eg, first drive in the morning. It usually takes between 1 to 2 minutes before it responds. But once the car picks, it works fine for the rest of the time, except when it is packed again for long.

I am trying to troubleshoot. Any help please.

It's called Morning Sickness.

I see you quote the same car in your signature. Any ideas?

Usually, it's a clogged line pressure solenoid in the valve body. Gears 1 & 2 will soon be affected if not already. No problems with the reverse.
Options: (i) attempt to clean the solenoid; (ii) attempt to replace the solenoid; (iii) replace the transmission.
