I was driving my car on the highway has normal yesterday and all of sudden my VSA light and check engine (that looks like the transmision) light came on. I immediately drove it back to my mechanic. It felt like i only had 1st and 2nd gear. i was driving 55 on highway and my RPMs were around 4.5 and 5. when i slowed down when the car downshifted it buckeled rather than coming to a slow stop. any ideas what when wrong?

 

well, what codes did it throw?

 

no codes.
its an automatic transmision. and my D (drive) light was flashing. i put the car in neutral and it came up as a red light. VSA was solid and than check engine light. no codes.

 

it could be a number of things.

you need to know what codes it threw, ask your mechanic.
he should have hooked up a machine(a little code reader) underneath the dash.

Autozone also provides free code diagnostics.

 

That sounds very similar to what happened to me last tuesday! I now have a new transmission! Check my thread "another one bites the dust"

 

mechanic says he has a new sensor getting shipped in today. lets hope that's all it needs.
no warranty or nothing. out of pocket : (

 

3rd gear pressure sensor?
or the APP sensor?
you should have asked what code it threw when you spoke to him

 

.... you're right. when i hear back from him ill ask the code and repost
