#1 of 16 Pontiac Sunfire transmission by g0m3s Jul 12, 2007 (10:47 am)
I have a 1997 Pontiac Sunfire GT with an automatic transmission. Whenever I make a left turn at a reasonable speed it will shift down for a split second and shift back up, then will stay in gear (2 I think) for a few second and then shift back down for another split second and quickly shift back up and then will stay there as I accelerate away from the intersection. I thought it might be the way I drive, but it keeps getting worse. Any idea what could be wrong?

I took it about 7 or 8 miles,,on my way back there was a BANG like something had let loose,, and it felt like i was draging something,,but nothing there,,when i got it back to my home,,it has not moved,,will not go forward or back it will start but no movement,,,Now i have been told it;s the tranni,,,could it be the shaft,,could it had been broke some how when they did the shifter cable,,Someone please help me here,,I need my car,,, Replies to this message: acadian (Aug 13, 2007 5:50 am)

Replying to: weecat90 (Aug 11, 2007 9:12 am) I would guess the shifter cable broke, seeing that after you heard the bang, the car was able to drive home. Bring it back to the mechanic that fixed it originally, it should be at his expense if it did break.

#6 of 16 1997 Pontiac Sunfire - 5 speed manual transmission by jamarengo Jan 07, 2008 (6:11 am)
Hi,   I need to bleed my hydraulic clutch. Anyone know where the bleeder valve is? Is there anything I should look out for when bleeding a manual clutch that is different from bleeding brakes?   Thanks, Jim
#7 of 16 transmission trouble, shifts gears hard at low speeds & RPMs go way up by driveit3 Jan 17, 2008 (9:58 am)
2001 sunfire, 103000kms. I was returning home from a long trip on the highway doing a constant 110km then the RPMs would go way up unnecessarly ( going up by 500). It would constantly keep doing this , approx every min. So i went to a lower speed same thing. And the car also had less hp, extremely bad going up the hills ! Was getting passed by transfer trucks! BUT , when i brought the car into a GM dealership they could not find anything wrong. I picked the car up and it worked fine, until a week went by then it happened again. Brought it back to the dealership, 6 hours later I get a call the car is working fine they couldn't find anything wrong with it. I'm wondering if every time i bring the car in the techs at the garage reset the computer on the car,....because they can not find any error codes. SUNcrape. ANY ONE ELSE THIS HAPPEN TO >>>>> help Replies to this message: pontiacsucks (Feb 22, 2008 12:40 am) driveit3 (Mar 03, 2008 2:29 pm)

Replying to: driveit3 (Jan 17, 2008 9:58 am) My son's car (2000 Sunfire) had similiar problem. Went on for about a year and finally wouldn't shift out of 1st. $2450 later (transmission repair) and $900 in 2 other repairs which left us stranded on the road (instrument cluster and ignition switch), we are selling the car. I would give you the same advice! Replies to this message: driveit3 (Mar 03, 2008 2:29 pm)

Replying to: pontiacsucks (Feb 22, 2008 12:40 am) Thanks for the response. I was planning on selling the car any way this fall. Now i am certainly am going to sell IT. Pontiac Sunfire sucks!
#10 of 16 5-Speed rev'ing after shift by slackerman Apr 23, 2008 (5:32 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! Replies to this message: slackerman (Feb 17, 2009 4:26 pm)
