Update time again got van back today yippee rattle gone from engine aircon compressor replaced , service done to AT software update done , fluid flush and renewed , drove home 5 kays and it was back to same problem seemed worse than before 4 times it slipped at intersection "bastard" had to stop and restart right in middle of road drove off fine 300 metres along at lights does it again then twice more driving up hill to home and then it slipped going along our driveway !!! . It seems that its fine whilst driving normaly as soon as you lift off accelerator as you stop or slow down when power is reapplied it slips again . Restart fixes problem I just dont get that part . Any way VW man told me that they were approaching VW for new valve bodies , that was at dealership . When I got home I rang him and told him that when he talks to VW tell them not to bother with valve bodies I want a new tranny as its even worse than before it went in . When I picked it up he tells me that the turbo is leaking oil somewhere so I ask what new seals to sort leak oh no he says new turbo , another $2500 on top of the $3680.20 I already spent on the other stuff , I will now play the wait and see with VW , I was happy when he told me that the service was done on the AT only to be crushed when the mongrel slipped like it was on ice . Will keep you updated with further news .

Mate, valve body doesnt fix it, if it gets a new valve body itll be ok for around 6 mnths then be same again. The trans makes metal that stuffs the valve body so itll need an overhaul with the valve body. Only my opinion, but seen it many times, you have the 09K trans and its the big brother of the 09G in the Gokf, Beetle, Polo, Jetta etc, all do the exact same. The original valve body gets reamed out and re sleeved with the fix and an overhaul is the go. Only going on what ive seen ( plenty) , but you have to play with the rules i suppose, just my opinion, reason i have confidence is i do a fair bit of work with trans shops and i take more than just a look when the trannys are apart.
Hope im wrong
Cheers

Just went for a 50kay run around the bayside hills and flat sections was all good until turned a corner and back came the thumps now after service its doing it in third as well as the 4th to 5th etc , what was real bizarre it seems under heavy acceleration that it skips 5th gear goes from 4th straight to 6 th . then about a kay from home more short runs with corners slips again then goes okay until turn into our street with an uphilll climb and it goes full slip mode . The question why turning it of and on fixes it I just don,t see the correlation of turning the car off and on to stop it slipping , I,ll just wait for a response from VW , but as I have said all along they would not service it 3 years ago now they have and its worse .

Further update as we had a weekend booked for weeks up at Stanthorpe no bloody auto was going to spoil our weekend at the wineries etc . It all was fine until near Ipswich at the Cunningham merge slips again 3 times in short distance as I have said I do not understand how just turning it off and on sorts it out really bizarre . Onwards we went all good whilst at highway speeds even went up Cunninghams gap withut to much fuss just seemed erratic on which gear it wanted to use , all good to Warwick and on to Stanthorpe . Played up slipping etc Saturday a few times and then was fine for rest of day Sunday morning did it a couple of times but always when slowing down to either stop or turn corners etc once up to highway speed it seemed fine . I will give VW till tommorrow to reply and then start jumping up and down . Whilst I can do the neutral shift turn off and on real fast the wife cannot and is now scared to drive it .
