ManwithSupra Posted September 24, 2005 Share Posted September 24, 2005 I have been having a few issues with my car recently and i wonder if anyone can help me with a few questions i have. For some reason under heavy acceleration more often than not the gearbox wont change up 3rd - 4th it would just hit the rev limiter in 3rd unless i eased off the power and then it would change up. Has anyone come across this at all ? I havent had a chance to check the tranmission fluid yet would this cause this problem if it was low ? Also when i started her up this evening she was misfiring until i gave her a little rev and all was ok - what do you think this may be ? A few days ago i had to have my car jumpstarted as the battery was flat and after that my speedo went funny along with some electrics that seemed to have resolved themselves. However does the ECU control the gearbox if so do you think a ECU reset will be useful. Please help as i am getting a little concerned Quote Link to comment Share on other sites More sharing options...
ellis Posted September 24, 2005 Share Posted September 24, 2005 My assumption would be that the ECU does govern the auto box - I reckon a reset would do the trick. Quote Link to comment Share on other sites More sharing options...
absz Posted September 24, 2005 Share Posted September 24, 2005 i would start by checking the fluid level first, as low level will affect gear changes Quote Link to comment Share on other sites More sharing options...
carl0s Posted September 25, 2005 Share Posted September 25, 2005 yeah I'd say check the ATF levels, but it does sound like you screwed up something relating to the speed-signal, which of course the ECU uses to control the autobox Quote Link to comment Share on other sites More sharing options...
