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.

While trying to bleed the clutch , The bleed clutch valve was damaged. I have tried to replace it but with no success . In this regard i will appreciate it if anyone can tell meabout how and where i can get this bleeder clutch valve. It is manual transmission.

Is your car an ecotec? i'm having the same problem I have no clue what it is I changed the transmission, the computer, and gauge cluster, and even ran anti slip for the tranny and it just won't work

I have a 2005 Pontiac Sunfire with a 4 speed automatic transmission and a 2.2l ecotec. The car is used for 1/3 mile dirt track racing. I'm having a very big problem I burnt up a tranny at the begining of the season and changed it. Now the car runs fine during the heat races and shifts fine (i put the tranny in second not in drive) however when i race the feature after about 10 laps the car stops shifting it feels as though the car is slipping. But if you let the car cool off and start it later it will shift just fine. One other thing is that the speedometer goes off when this happens. I've tried a new computer and also unplugging the gauge cluster I don't know what to do anymore.
