My newly acquired Cayenne was suffering from harsh down shifts mostly from 4-3 but sometimes 3-2 (under load). After researching all the options I decided to order a rebuilt valve body from http://www.revmaxconverters.com/

The order was shipped out within a day and when the valve body arrived it looked like a new part and they also include a return shipping label. My mechanic did the change but I supplied the valve body, parts and trans fluid (I went with Mobile 1 ATF 3309). The total cost ended up being just under $1200

The transmission now shifts MUCH smoother with no harsh down shifts at all.

Revmax also processed my core charge refund within a day of receiving my old valve body.

If you need a valve body I would recommend Revmax.

Thanks for posting this review, I'm considering Revmax for a rebuilt valve body on my BMW and I feel much better about that after reading your review.

Still going strong?

What was your mechanic's itemized labor charge? Thanks.

I echo your sentiment OP. My post from another board:

Got the cayenne back from the shop for the alternator and decided to tackle the valve body this weekend. I knew it needed to be replaced when I bought the car so it was a necessary expense. Guys from Revmax hooked me up and sent me the kit on Wednesday to arrive Friday. Got the fluid from Amazon (mobil 1 same specs as factory for about 1/8 the cost) and a case of beer for talking a friend into helping. After getting the car jacked up and everything taken off it was really an easy job. Took us 3-4 hours total. VERY VERY MESSY. Holy hell. I have a large drain pan but it kept leaking on the ground. Once the pan is out it drips the entire time you're working on it, and it's difficult to work on just on jacks with the pan in the way so we just dealt with the mess. Anyway, downshifts are now perfectly smooth and the only rough upshift is 2>3 but its only about 10% as rough as it was. The fluid that came out was dark red like robitussin. What went in is nearly opaque red. Big difference. Props to revmax. If you're thinking about doing this yourself, I'd rate it a 4/10 on the difficulty scale. Just be patient, don't use force on the wiring and pay attention to the details. Everything else is simple.

Since I did the work myself I'd estimate my total cost somewhere around 750-800.

Yea, as far as the mess goes, as a minimum if available pull the plug and let it drain overnight or longer if able to let it drip.

Really wish I had done this. Had no idea it would drip like it did the entire time.
