the gears seem to be a bit strange as in often when you are for example driving along at 40 then you slightly press throttle nothing happens press a little harder and slight ecceleration press a little more and she drops down 2 gears then races off. or going up a hill when you can feel it needs to be in thrd and she's in fourth. i was told the tcu can be updated with new software which greatly improves the changing of gears i was also told the later models had a tcu with improved software. which i suppose should really have been my original question. is the ar tcu a later model with updated software and will it fit or have i been misled? :-/
wish i had taken note of fault code when i was at the garage i know this would help. think it said tps signal not present. there were more serious issues but those are now fixed thanks to this site. for anyone interested. flickering gear lights{auto} random gear selecting. answer new gear program selector switch. quoted £450 from vauxhall plus fitting. haynes said you need to drop the auto box to fit it. i got it for £4 from local scrapyard took half hour to fix and align and didnt need to drop box. anyway without incuring more diagnostic costs and with the local scrapyard having a 2.2 auto is it worth me trying the pedal or something else. thanks for all yr help. j
