my 2001 2.2 petrol autobox seems to hold on to its gears for a long time(especially when setting of from a standstill on a hill)gear changes are quick and smooth when the engine is cold,but once warmed up the engine revs to just over 4 thousand before 2nd gear is engaged,then same for 3rd gear.always has a smooth gear change .although first thing in a morning it does seem to go from park to drive with a thud,ive checked the auto transmission fluid level,that was fine,and its colour was a very clean red...
gear selector works fine and i have no warning lights or messages coming from the dash...the car has done 84 thousand,no towbar fitted.any ideas,
neil..

any engine codes stored?  or transmission?

have you changed the fluid, or just topped up?

have you ever had the software on the autobox checked / updated?

no codes stored in the transmission
topped up the gearbox with engine running but didnt take much,was pretty much full
never had an ecu update done.
can the filter in the gearbox get so clogged it would reduce the fluid pressure ,hence the need for high revs?

Interesting........ DLK commented on mine when we we went out at the Lakes Meet, he seemed to suggest it was holding the gear for a while..... :-/ :-/

My experience is that when cold, holds first for a long time, slow acceleration..... If you drive with your foot to the floor it will hold the gears a more gentle drive and the gears will change up quicker....... :)

I am currently doing unscientific tests which seem to suggest that I get more MPG when driving normally in Sport mode, particularly around the town..... :-/ :-/ :-/

thats the weird thing about mine,when first used in a morning,it slides through the gears fairly quick,drives lovely until warm.hates changing gear on even the slightest of inclines,from a standing start.

Right, that does not sound right to me, and quite used to 2.0 / 2.2 Auto's hopefully someone with more technical knowledge will be along with some advice.... :y

would the filter in the gearbox get so blocked as to reduce fluid pressure to the servos in the box,or could this be a sign that yet another component is slowly failing..got car in nov 2010,since then ive changed the following,all genuine gm parts..
air flow meter
cat downpipe
both lambda sensors
camshaft sensor
new rocker gasket{now no oil in plug wells)
spark plugs(bosch super 4s)
exhaust manifold plus gasket..

just an update to do with the problems ive been suffering,ie holding gears for a long time etc,eventually eml light came on and gave code p0130,lambda sensor position 1, part number 9202577,changed that,and what a difference,lovely smooth gearbox,changes gear quicker,engine feels more responsive now,at long last it now drives nice...hopefull better mpg to.for the last 10 months this car has caused me nothing but grief,but for some reason,i still think everytime i get in it,i dont know what else ide rather have :@)
