i got rid of my 93 bonneville ssei,,,,, and got a 1999 pontiac grand prix gt with the grand prix i am having tranny problems it is the 3.8L non supercharged it has 245,000miles all orignal from 1 owner ,
it shifts from 1st-2nd fine at like 25mph ,and from 2nd to third it wont shift ,it goes stright in to 4th ,and then o/d fine , i had it tested and it says 3rd gear isnt engageing
so i am trying to figure out what it could be it seems like it trys u can feel a buck
it shifts from 2nd in to forth right at 45mph and wont shift untill you hit that speed.
THINGS I DID-
i had the tranny filter and fluid changed no shavings and it wasnt that bad
and i got a code po717 and po716 speed sensor but this just started .
SO ANY HELP WOULD BE GREATLY APPRECIATED CAUSE I REALLY WANNA FIGURE OUT IF MAYBE ITS JUST A SENSOR.thanks for replys!
o and were is the speed senor turbine thing located in the tranny?
