automatic gear problems

Hi 2 u all,
could anyone help - having had my 98 grand voyager 3.3lx for nearly two
years i'm experiencing problems - the gears seem to change for no reason
rather than the previous comfortable exchange - they change down for no
reason and it seems she cant decide what gear to be in - at low speeds she
keeps going up and down the gears for no reason - furthermore when getting
upto to higher speeds she wont go into top gear and high revs in the lower
gears - can anyone offer any advice / tips prior to me getting an expensive
garage bill,

thanks in anticipation of any responses

 

It sounds like one of your transmission speed sensors is on the edge of
failing. When the TCM doesn't get an adequate signal from one of the
speed sensors, it goes into limp mode where it forces it into 2nd gear.

If that's what it is, the sensors are $20-35 each. A 20 minute DIY job.

There could be other explanations, but that one comes to mind.
