I had an oil change about a month ago and engine-transmission program updated.
Texaco oil was used,nearly 8 lt,original filtered.
It drives better,gears are smoother,but this started new: all of a sudden you take your foot off the gas, and then put it back on and it goes "THUMP" and kicks into gear.
Is this acceptable?

Sounds like its taking up slack in the drivetrain. From the wheels to the gearbox all the components can get a small amount of wear, this adds up to play in the whole system. It's often worse in the higher gears after the TQ has locked up. I notice it if driving round country lanes and I back off the throttle and then reapply.

What's your mileage? I notice this at 120k.

I have a TDV8 and the box is very smooth but does occassionally thump just a little when its changing down/engine braking.

Could it be that the gear changes are so smooth you're now noticing this more where as you didn't before? Or is it really that much more noticeable?

Obviously if you have had work done then that makes one think that could be to blame, but I don't know how a simple oil change could cause this issue, the theory I was going by was that I have a different gearbox but I get a slight clunk too. So the only thing left is the drivetrain - Hubs, UJ's Prop Shafts, Diffs etc?

Just an idea.

Possible.Because it was harsher before reprogramming.
Will this occur if enough oil wasnot filled?

It is much more noticable in low gears.
