180sx AUTOMATIC problems

[sshep46]

I have just purchased an auto 180 with a CA18det. The car wont change past 2nd gear. 

The speedo doesn't work - Its sitting maxed out at all times (not on 0)

Theres plenty of transmission oil.

I've disconnected the Speed sensor on the auto gearbox and nothing has changed - does this mean its definitely the sensor? If so does anyone know where to purchase one? Nissan wants $350 and theres none in australia....

Did the car display this behaviour before you purchased it? Or did it work and then stop working?

[sshep46]

No it was like this when purchased. Supposedly it has been sitting for four years but did work prior to being parked up

Oh ok. You bought it so you must have had some idea how to fix it. Good luck. Sounds f**ked.

Could be a broken speedo. Sounds like you bought someone else's problem. Good time to learn how to fix cars though, so start taking it apart. Stuck in 2nd gear is limp mode, so something is up with either the control unit or the box is stuffed.
