I need help with my 88 sunny 1.3 auto... it's the same auto transmission as in the 1.6. It is carbed. the car will acellerate in first gear. It won't swtich to second gear unless i am really fast and let off the gas. It won't switch to third unless i do the same thing.

Now i have taken the govener out. the gear is not stripped. I have a new gear i'd like to put on it but i cant get the stinking pin out. Argh. Any help would be appreciated. Thanks

Hi Sam,
The pin that holds the govener gear on is usually a roll pin, and should have a split on one side. If you stick the govener assembly on something like the jaws of a vise, and use a trensfer punch, or a broken drill bit, that is slightly smaller than the diameter of the roll pin, you should be able to "tap" it out with a hammer. Since you say that the gear on the govener looks fine, you should also check the cable linkage that goes from the throttle plates to the transmission. If it were out of adjustment, or broken, the transmission would think it was at full throttle all the time, and wait untill you hit a high RPM to shift. If it does not have a throttle to transmission linkage, you might have a broken or leaking vacuume modulator (never seen one on a Sentra though).
Bob
