Question about 1992 Saturn SL1

1 Answer

I have a 92 Saturn SL-1 and it runs fairly smoothly except the auto. transmission shifts hard at times. However, the gas mileage has dropped to probably 15 mi per gallon. I have replaced the fuel filter, air filter, and used a quality fuel system cleaner with some improvement. Gas mileage is still horrible. Could there be a fuel injector or fuel pump problem?

Try changing fluid and filter. If this does not correct it, then test the vacuum pressure in the vacuum controlled actuator and the circuit on the tranny. If it turns out ok, then tranny servo or other internal part may be faulty

My standard 99 Saturn sl 1 acts like its running out of gas when I shift up from 1st to 2nd is it fuel related ? Transmission related ?


If it starts fine and runs. It could be the fuel filter. I would start with the fuel and air filter. And check fuel pressure.

My 92 saturn sl burns through gas way too fast. I barely make it 30 miles without having to fill up again. What do i need to do to get better gas mileage?


Need some more info. How much gas are you putting in it? Does it smell like raw gas at anytime? Under the hood or under the car? Possible broken (rusted) fuel line. Any service engine lights on? Does the car seem to run well?

Transmission shifting very hard


Unfortunatly my transmission does the same thing. I had it repaired for about $800 only to have the same thinig happen again about 4 months down the road. It seems that there are alot of horror stories about these saturn transmissions. My trans has been slamming for about 3 years now and it still works...per say. Id say either replace it or just drive it until it breaks.

1999 Saturn sl with shifting problems first gear and reverse


Ms Derry ,I would check the pair of shift cables and shifter itself before suspecting internal transmission problems.The cables attach to the shifter then runs to the linkage on the transmission.One cable is responsible for side to side movement as the other is for moving front to back(like 1st to second) Center console removal is fairly simple which requires mounting screw(4) removal on the front sides and in the rear cup holder.This gives you an opportunity to view the shifter and cable operation from above while this movement should also be appreciated at the transmission linkage meaning someone shifts the vehicle as another inspects proper movement at the transmission.If all this is actuating properly,you may need to tear down and inspect transmission but hopefully it can be rectified with external repairs mentioned...good luck

1999 saturn shifting hard what do i do boys


Check the transmission fluid level and condition. Make sure the level is correct, if it is then it may be time for the transmission for service. The transmission service time is every 30,000 miles, and if it has not been serviced the Transmission line pressure solenoid could be gummed up with dirt. Have the transmission fluid flush and the transmission oil filter replaced and hope that helps. Hard shifting is a sign of fluid restriction in the valve body in the transmission and will lead to a costly transmission failure. Good luck and keep me posted, the other thing to that would give you a hard shift is a bad throttle position sensor. But that should have given a check engine or service engine light on.

My saturn sl2 is shifting hard on his bad days


Yes, with another transmission...they have a problem with the valve body going bad. Go with a junk yard trany. Just make sure that it has low mileage. $700 is a ball park figure...$700 for labor.

1998 Saturn Sl 1 Won't start some times.


I could not find any diagrams.......but it may be the park lock cable.. or you could have something jammed underneath the shifter.... a penny....or some other misplaced object that can slip underneath the cracks and cause it to not go into park all the way....the center console is fairly simple to remove a few bolts and I think a couple pop rivets.... a Haynes Manual on all the s series Saturns is available at your local auto parts store (advanced auto, auto zone, Pepboys) it'll run you like 20 bucks but will definately prove helpful to you ... Im looking at mine right now and it shows you how to completely tear it down and rebuild it.
