I posted a thread a few months ago I was having while replacing the valve body in my 04 3.2. I bought some "bad" used valve bodies that were being sold as remanufactured and was having issues. (See previous thread here if interested 04 3.2 Touareg won't move after valve body replacement) I ended up buying a legitimate remanufactured valve body from RevMax. I installed it and it has been shifting perfectly smooth the last 3 months. I put approximately 1000 miles on the touareg since installing the RevMax valve body and there has been no problems. Yesterday I get into the Touareg to go for a drive and it starts out fine shifting through the first 3 gears, then all of a sudden while shifting into 4th gear it "slips" out of gear and just revs like in neutral, then clunks hard into 5th gear. It was driving perfectly fine the day before. I tried driving for a few mins and it seems that every time it shifts into 4th gear it "slips" out of gear. I had to limp back home giving it very low rpms. It seems when trying to go anything above 2000 or so rpms it slips out of gears in 4th-6th gear. For some odd reason it seems to work fine in 1st-3rd gear and reverse. To me it seems like a clear valve body issue. I just cant believe I had another valve body go bad. I haven't taken anything apart yet, the only thing I did was get the trans temp up to 40 or so deg C and remove the fill plug and weirdly alot of trans fluid came out. At least a 1/2 quart I would say. It wasnt dripping out like it should. The transmission level was filled according to spec 3 months ago when I installed the Revmax valve body. I have already contacted Revmax and am waiting to hear back. Anyone have any idea as to what in the hell could have happened besides another valve body going bad?!! This just seems extremely odd to me how it was shifting fine one day and then the next it is shifting like I have a broken valve body again. Any suggestions would be appreciated. Also there are no stored fault codes except a tiptronic switch implausible signal, but I have had that fault for the last 5 years. I am 99% sure that has nothing to do with this issue.
