Are you sure you're not stuck in 3rd gear? It seems unlikely that first gears tops out at 80mph. Does it feel really sluggish when starting from a stop? Many cars have a "limp-in" mode that holds the transmission in 3rd or 4th gear but that is also usually accompanied with a check engine light
I am having this problem! My car is really sluggish when starting from stop and I can go 70 on freeway, but it's not changing gears. My check engine light came on too. This is all after having a bad transmission fluid change. What do I do? They're saying I just need a new sensor.
yes check engine is on

My 1999 SE was having a similar issue with being stuck in first gear. It wouldn't drive over 35mph but i check engine codes and replace the variable speed sensor around $45. It fixed all issues. it is on top of the transmission coming out at a 45 degree angle toward the driver side. If your car is stuck in 3rd this may not be the case, i suggest you check your codes and start with whatever the codes suggest.
Check the neutral safety switch...I had similar problems and replaced mine and it was fine!!
noke sensor my dear

my self, i;ve washed all the sensors with wd40 and it worked fine for couple months and later all of them faild unfortunatly. ahahaaa
There is a shift control solenoid available from AC Delco # 19113523 and other manufacturers for your vehicle, But you should have a transmission expert check it before you damage you engine from over revving.
