2000 GC Trans Question

There is what's called the "range sensor" on the transmission. That is an electical contact assembly that, via the open/closed states of it 4 or 5 switches, tells the computer what position it thinks the gear selector is in (of course if it is telling the computer that it is in Reverse, the computer will display 'R' and not allow you to start it - so the computer is properly doing its job).

Either the linkage cable between the gear selector and the range sensor is having problems (is it binding up at all? IOW - does the gear selector move normally - i.e., not tight or abnormally stiff?) or the range sensor is crapping out on you, in which case it would need replacing. Probably bad range sensor.

Thanks for your quick reply, the gear selector moves fine, not abnormally stiff or binding, except for this issue when hot I wouldn't have known this part may be failing. Do you know if this sensor is easily accessible to replace? I will price one out at the local dealer.

You're welcome. The transmission pan and valve body must be removed to access and replace the range sensor

That's to bad, I was hoping it was as simple as opening the hood and being a

Could be worse - at least you don't have to pull the tranny. :)
