If my transmission is bad or going bad would my check engine light be on or it doesn't necessarily have to be on when the transmission is bad or going bad?

 

Well its a check engine light...not a check tranny light. So no it dosent have to be on. Just take it to the dealer for crying out loud.

 

What Is The Issue?

 

depends on whats going on.

 

If your were not having this problem before the mount broke, yes its the mount. In a transverse mounted engine with a transaxle, when you break a mount (especially on the front or rear of the engine) the motor will rotate when torque is applied (i.e. when you step on the throttle). The mount must be changed. This rotation can cause other anomalies, such as sluggish acceleration due to the fluid not flowing properly through the valve assy in the automatic transmission. If you can replace the mount on your own, do so (unless the dealership will cover it under warranty). The sooner the better. I have also seen throttles stick like this, so be careful.

Hope this helps.
