Spent this weekend doing the filter and  fluid change on the auto box. Had the lurch when coming to s stop (once gearbox oil came upto temp). The change seems to have cured it by around 80% i reckon. Only lurches every so often now. and it seems to be when coming to a complete stop from quite a speed such as 30-0 rather than gradually slowing down. I will be doing another filter fluid change in around 1k miles to ensure majoority of the fluid is new-ish.
Also did the transfer box and 2 diffs. My what a difference, So much smoother.
Used Texamatic 7045e in the Transfer Box and Box.
75w-90 Fully Synthetic GL5 Gear Oil for the diffs.

Cheers

Sounds like a result.  Mine didn't like rapid stops so whether the gearbox just can't downshift fast enough, or doesn't bother until you're almost stopped I don't know, but it's annoying.

It would be a great help if you could put a shopping list up, with the quantity of each oil used Please.
I might do mine this spring. I had the auto box serviced at an Auto Gearbox Specialist last year as a preventative maintenance job. No problems before or after thank God.

For the diffs (used just under 3 litres in total)

http://www.fleetfactors.co.uk/lubricant ... 7045e-p387

For the AutoBox and Transfer Case/Box
The autobox used around 4.5 litres (thats what came out) and the transfer case used around 3/4 of a litre.

Hope this helps.

I assume you have the 5 speed gm gearbox as the zf6hp26 uses a different transmission fluid
