hard shift / flare shift = valve body
I wanted to put my experience out there because I dealt with lots of issues and avenues for replacement and found one solution that worked very well.
First I have a 08 Touareg and when at about 80K miles I was driving up a hill and went to pass somebody like I normally could and when the vehicle went to downshift It as if It went in-between gears and revved up to 5000 rpm and then slammed into gear. I slowed down and waited for a transmission or engine light Nothing. so I tried it again and the same result. I was freakin out, I had just passed my powertrain warranty and thought I was screwed.
I tried something else, when I wanted to pass somebody I used the Tiptronic method and downshifted letting my foot off the gas slightly between shifts and everything worked perfectly.
I drove like this for another 40,000 miles and it never seemed to work itself out or get worse. I did a ton of research contacted about 20 VW Audi Mechanics and could quickly tell the ones who didn't want to deal with it and the ones who were up for a challenge. I'll skip all the conversations and tell you the most helpful
This was a VW specialist and he told me 3 things to look at.
1. check the fluid level if it's low it could just not be pushing enough fluid to properly move the valves.
2. because the triptronic method works fine does the rig pull or slip like it might be a clutch problem
3. Watch the heat of the transmission because It could be a wiring issue and heat will ruin wiring and put you in limp mode.
His conclusion was it's likely just a valve body if the fluid was full and the clutch was fine.
I had the fluid checked and indeed it was dark, not pretty and pink like new, and the clutch was fine no slipping. (at the end of this I'll detail an issue that may present as a clutch issue)
So I read on some forums here on clubtoureg about valve body replacements the best site to get them is revmaxconverters . com/product/09d-tr60sn-oem-updated-valve-body/ Simply the best. don't bother with any other place. get your fluid and filter from blauparts,com they have a whole kit and it's fantastic. it's not going to be cheap, kit and valve body are going to set you back some 800 USD, and it's about 3.5-hour job from a shop.
Personally, I wouldn't just change the fluid because at 200$ a kit that's a hefty amount of coin to just toss away.
the whole process went super smooth and when it was all done have the shop perform a gearbox reset, or manually do it by following this process
1. turn key on but not start.
2. push the throttle all the way down for 10 seconds (repeat 3 times)
3. let off the throttle and turn the vehicle off.
Simple. works perfectly.
When I went for a test drive I expected the issue to come back but nope, I had my old Touareg back, and she runs like a beast. even at highway speed, I could mash the throttle and it would shift perfectly normal and fast too.
Now for the issue that may present like a clutch issue. When your accelerating and the vehicle shifts into 3-4-5-6 gears and if feels as though your RPM's "dipped". You'll know it when you feel it and hear it. it's not a smooth acceleration scale there's about a one-second dip in RPMs. this is a timing issue. Chances are if you've felt this your Reg has higher miles, or if your Touareg has higher miles look for it. I'm not positive about expressly chasing the timing chain on these wagons but if your hyper performance oriented then you might look that way because the system is compensating for a little timing lag due to a couple of worn components. Point is it's not a slipping clutch but a timing compensation.
hope this is helpful. cheers.
