#10 of 23 5-Speed rev'ing after shift
Apr 23, 2008 (6:32 pm)
My 1996 Pontiac Sunfire (2.4L, 5-Speed manual, 127,000 miles) has developed what feels like a slipping clutch, but is not. After driving the car 10 miles, shutting it off for 20 minutes, and then starting out again, I can shift from 1st to 2nd, or 2nd to 3rd, and the engine will rev as if it is in neutral before catching and slowly accelerating.
Anyone else have this problem?
I've had a trustworthy garage check the clutch without result. Could this be some sensor or an electrical issue?
Any ideas? I love this car and don't want to give it up!

I had to replace the transmission in my 2000 sunfire coupe not shortly after I purchased it at the beginning of this year. However, not too long after it was supposedly "fixed", I noticed a grinding between 1000-2000 RPM, between 35 to 40 MPH. This has been going on since May. The car never had any pick-up and go, but this all changed significantly when the transmission was fixed. Nevertheless, I still feel and hear the grinding, in spite of the fact that everyone I've asked to drive/simply be a passenger and listen has not felt/heard anything. One of my previous cars died from transmission problems so I do know what I'm talking about. The question is this: what part could it be that needs fixed? I only experience this one problem. Has anyone else out there got the same grinding in that gear?

i guess where talking about an auto tranny here. if it was replaced and started grinding , i would take it back to where it was fixed , should be under some type of warrenty. The pick up and go sounds like a torque converter prob, but could also be a bad transmission, if this is a manual tranny i would say you have some ring gear problems which will just get worse over time..

The problem was the ignition coil.

My 2001 pontiac sunfire will not shift into overdrive.
The previous owners replaced the transmission, and it still will not shift into overdrive.
It tops out around 50 mph at 4k-5k rpm.
If anyone can help me diagnose this problem i would greatly appreciate it.

So my '99 Sunfire was leaking tranny fluid and coolant. We checked to see if I blew a head gasket but there was no coolant in the oil. We changed the radiator and now my check engine light is on and if shifts really hard. There is also tranny #2 in the car. Anyone have any advice on what I should do/change??

I actually had the same thing happen to me, but I have a Pontiac Sunfire 95. It was extremely hard for me to go up the hills. It wouldn't go more than I'd say 10 mph. The RMPs would go up extremely high as if the car would just go into neutral. The car wouldn't go more than 45-50 mph when it was on leveled ground. It stopped for a week, but after a week it started happening again.. Well I took my car to the mechanic, ends up i need a whole new transmission.

#19 of 23 transmission/wiring problems with 2002 Sunfire
Sep 06, 2010 (7:46 am)
Automatic transmission. About two weeks ago I was driving down the freeway going 70mph and suddenly my rpms flew up and I had to exit the freeway, the rest of the way home I could not get out of first gear. I assumed my transmission was fried, so I took it to a transmission specialist. I drove it there, and it shifted fine, no problems. They scanned it and got codes that all of the selenoids (?) were bad, which they said was pretty unlikely, so they cleared the codes and gave it back to me. They said if it happened again I would need to take it to a wiring specialist, which I did and they gave it back to me and said they weren't sure if they had fixed it or not, (they didn't charge me anything).... it is def not fixed, my check engine light is on and it will drive fine and suddenly the rpms will go flying up and it will shift really hard, then be fine again. ANY IDEAS??? Thanks.
