Jonathon, what kinds of transmission problems were you having before your engine blew? They told me it takes 3-4 weeks to get the core refund back from the time they receive the core.
I called Revmax, they didn't really seem to want to help me at all, had less than a 2 min conversation. Said I need to adjust something on the valve body, it will speed up or slow down engagement of the clutch, and he would send me an email. I attached what they sent, I think loosening the screw speeds up engagement which is the opposite of what I want. Nothing else was included in the email, just the picture.
Think I'm just going to stop at some local Transmission shops next week, someone has to be able to figure it out.

Well, you know you cant take the pig anywhere without someone trying to BBQ your rump, I would go ahead and replace the harness and adjust the screw while you are in there before you give up.

My trans was doing a hard 1-2 upshift, and hard 3-2 downshift. When I reset adaptation after the valve body job it seemed really good, but I had incorrect fluid level and it got bad quickly. I filled it again per the procedure and seemed pretty good but came back somewhat... I figured I was losing fluid over time causing it to come back. I did find trans fluid up to the TCM, but I thought how would that dmg electronics? It is a di-electric is it not? wouldn't it just insulate it? I'm not an electrical guy per se so I don't know these things very well. I can do wiring etc but theory of electrickery escapes me...
I prefer the mechanical stuff.
Anywho hope that helps you!

+1 it doesn't cost as much as your other options so I would go that route as well.

Revmax emailed me about my problems, they suggested not adjusting it as they thought it had a different problem. Took it into a local shop, they found so far some bad clutch packs. I don't have any specifics yet. This was as of yesterday and they were looking into ordering parts. I'll update when I get some more information.

If you ask me, it was shifting fine, because they clear TCM adaptation, so TCM was in learning mode. When my I had bad valve body, was acting as yours, and when I cleared TCM adaptation is was shifting like it should, but this last only around 100km, and then the problem came back.
It can be possible you still have valve body problems.
However keep us posted.

Alright. So I picked it up today, they said software update and reset the adaptations a few more time, they drove it for a day or two. Washed it too. Told me it was good to go. Pick it up and drove it, great. Shifts up smooth, no choppy downshifts while coasting. But, still an issue I just discovered. While in 6th if I give it a lot of throttle, it skips 5th (which I think it's supposed to do) slams into 4th and then immediately slams into 3rd. Does this 100% of the time from 6th gear. Also while in manual mode, up shifts ok, down shifts bad. Only played with it for a few minutes, but down shifting from 4th to 3rd is very very hard. I'm sure the shop didn't drive aggressively enough for these problems to show up in there test drives.
I just need it fixed before the snow comes, I'll be taking it back tomorrow.

Welcome to the forums. I think you're a bit optimistic in asking him this question since he hasn't been here since 10-29-2014 10:29 PM,
Thats almost 5 years.
I think you might do better starting a new thread on the subject. Please include a problem description and year/model of your Cayenne - preferably in the title. That will get you the best response from people who may be knowledgeable about the problem.

Wow, that is pretty wild on multiple levels:
1. You came back 5 years later to answer the question and had more information. That is epic.
2. The new transmission still did not fix it!?! Wow.
