I have a Saturn 1997 SW2 station wagon and the check engine light came on I did a diagnostic test on it.?

well first thing i'd check tranny fluid level with car running in neutral on a flat surface it should reach the cold fill line if you haven't been driving around or the hot fill line if you have been driving around. either way low tranny fluid doesn't carry as much heat away as correct amount i'd start there.

If fluid is within proper range, I'd take it to a shop. Overheating the tranny quickly leads to transmission failure. It could just be bad sensor but you have no way to check that.

>> My verify engine mild won't are available in my 1997 saturn and subsequently my motor vehicle won't bypass emission What? they are not think to be be ON. To bypass they could be off. ==== the two way, verify engine mild potential that between the sensors is broken. it particularly is conceivable on your sensors to be working all properly and nonetheless be failing emission. as an occasion, in the adventure that your gasoline injector is clogged, there is not something your engine laptop can do to desirable it. And your motor vehicle will fail - even however the CEL is off. it's time to take the motor vehicle to a DIAGNOSTICS center and do an old trend thinking to repair the motor vehicle. you may test the engine code. it particularly is conceivable for the laptop to shop slightly atypical values of sensor which could supply you clues to what's incorrect - however the values are actually not so out of norm that the CEL will mild ON. good success...
