I recently was given a 2006 red v6 from my mom for my almost 16 year old son. They live kinda out of the city near phoenix but in the desert. They have huge packrat out there and they got to some wires on top of the transmission. I'm just hoping someone knows an easy way to access these wires so I can repair them. I recently found a diagram showing where the wire harnesses are on the tranny and I can go scan the codes again to see which wire harnesses need checked. All the codes were tranny related and many were ground faults. I fixed the ground strap on the firewall by putting a piece of 1/0 ofc I had leftover in its place. This got some codes to clear but there's still plenty to contend with and from the trail of evidence they left behind it is pretty clear that's where they were staying. I hope I posted this in an ok spot. It's my first post on a forum ever. Any advice will be appreciated.
Thanks,
Nick

I've taken the powertrain out of one of these cars before. There's not going to be an easier way to access that harness for repairs than to remove the transmission itself, unfortunately. The problem is that the harness is secured down the spine of the transmission, and the transmission fits so tightly in the tunnel that you're not going to be able to reach above it even if you pull the crossmember and tilt it back.

I was afraid that's what the answer would be. Do you have any suggestions on the best way to go about this. I'm in the middle of swapping out a transmission for my jetta and I got it out surprisingly quick. I would like to take as little apart as possible considering that one of the bigger more important pieces needs to come out. I appreciate the quick response.
Thanks,
Nick

Removing the transmission is about the same as it is for any other RWD car. You'll want either a low-rise transmission jack or a sturdy board and good floor jack to support that transmission coming out and going in. As far as the wiring repair, match the gauges, solder the wires well, and try to keep the lengths the same, heat shrink tubing is your friend.

Never done it so this will be fun. Are there any special tools that I'll need. I have most things but definately not transmission tools if there are any. Any thoughts on just cutting through the floor, fixing the wires and welding it back? Can somebody link me to a walkthrough of pulling this tranny? I really appreciate the help and I'm starting to convince myself the right thing to do is pull the tranny. My hands are too big to pull off the miracle work others do.
Thanks,
Nick

Also, while I'm in there is there any maintenance I should do while I'm in there? The car is in pretty good shape but my dad does all the work on it but he can barely walk any more. If he gets under the car he might not get up. So some things have prolly gone forgotten.
Thanks again,
Nick

That's on a V8, but your 4.0 is similar.

Drop the pan and drain and fill the fluid and filter while you're at it if you're worried about it.

I'd honestly recommend buying a Haynes or Chiltons manual from your local parts store if you're unsure of any of it. I work on cars for a living, but the last time I worked on 5R55s transmission was two years ago, and that was in an Explorer. The last time I had one all of the way out was in a 2005 4.0L Mustang back in 2014. To me there was nothing difficult about it, but I work on stuff every day that would turn some of the savy guys on this site cross-eyed.
