Today while driving home I noticed that the powershift on my VL 4-speed auto appeared to stop working. When accelerating from a standstill, when the powershift was engaged (light on) it would drop into top gear as normal. Also engaging the powershift when cruising in top gear at 60-80km did not cause a gear change.
Some details:
•Fluid was replaced about a week ago. 3.4 litres approx~ of Dextron II. This was the first change I had done on this type of car, the manual said 3.4 litres. Is that the correct amount and type?
•I had been giving the car a good flogging as I was driving through some steep terrain and needed to keep my speed up due to traffic.
•Aside from this powershift fault, as far as this Layman can see, there are no other faults with the transmission.
•I pulled over to check the fluid levels when this problem started and I although I could not make heads or tails of the reading (which was way up past full - the engine was not running but was still at op. temp.) there was no indication of total fluid loss.
What are possible causes of this condition?

It's as if society expects me to act like a cockmongler when I'm driving the Commodore. People always look at me weird when I go the speed limit, or indicate for more than 2.5 clicks or accelerate moderately off the lights... wtf
basically its really an overdrive button to engage 4th gear.
Could be the plug under the T bar as well
or faulty button so the Trans ECU is not recognising button position.
i would suggest check plugs on Trans ECU i know that if it is unplugged it only uses First, Second and Third gears and not overdrive.
Located under drivers side plastic panel roughly where your Right knee is while driving.
Goodluck bud
overfilling the trans fluid causes many problems
check fluid level when all is warmed up and engine idling, put selector thru all settings first, yes its not easy to read fluid on dipstick, some newspaper against bottom of it makes things easier
how dod you get rid of the old fluid?helps to measure what comes out and to put in an equal amount of new fluid
easiest way to remove some is to undo a line to trans fuuid cooler, start engine in idle and some will leak out
these 2 fluid hoses should be replaced as they often eventually leak
Well I drove the car this morning and the problem seems to have fixed itself. Did the climb up McIntyre road with no troubles.
Is it possible I just trigged some sort of safety cutoff from the spirited driving?

i find that i drive approx 5 mins before things warm up and can shift into overdrive.
