Having problems with your 1999 Pontiac Grand Am GT ?
Changed transmission not shifting properly
\015 I recently changed a automatic transmission in a 1999 grand am se 3.4ltr.New fluid and filter.The tranny slow shifting at times.The speedometer stopped working.Changed out the vss sensor but no change. Also had the key lock up at same time.Replaced assembly .Did the ten minute to get the car finally going. I notice the passenger side driveaxle has a shiney portion on end shaft at transmision still showing about 3/8 of inch.Can't recall seeing this when I pulled the shaft out.Not sure if its completly in place,but seems to be when I tap on it useing large hammer and wooden drift. Please inform if possible. Stumped\015
If there still is a shiny portion still showing, you'll need to remove the shaft and double check the "C" clip at that the end if the shaft, going into the transmission. If the clip is still in good shape, take grease and "cake" it around the shaft and clip to hold it in place. Double check this and then we can move forward to the other issues.
Are the two transmissions have the same transmission codes on the transmission ID identifacation plate? if not you do have a problem with a miss matched transmission
