back in september the check engine light fallowed by the rest of the lights you guys know turn on and the transmission was acting up.
so bought the VGA cable the first thing i did was disconnect the battery for the hole day than i connect it to the FreeSSM and did a TCM reset.
The crazy light did not come back but the downshift to 1st gear feels a little harsh any ideas?

Yup, replace valve body. THis is probably the most common (although not very common) failure for our transmissions.

I had some shift issues that suggested the Valve body needed to be replaced several years ago - I still haven't replaced it and they went away. The only things I did?

Change the Fluid
Change the leaky hoses that lead to the filter & trans cooler hookups.

Fluid pressure being consistent is important, so definitely check for leaks and service your trans if you haven't recently.

No known codes, but I did have rough 2-3 shift and a rough downshift to 1.

Like I said, I did fix some leaks which could have been causing some fluid pressure dips, which *could* affect shifting.

I'm not saying it's a miracle cure, just that it would be good to service the transmission if it hasn't been and check to see if there are any leaks on the numerous soft lines going up to the radiator.

Noobie here, and thanks for the add.
I have a 2008 Tribeca 3.6L 5EAT AWD. It starts like this, my daughter was driving my wife's Tribeca a few months backs, she calls me and said that a bunch of lights on the dash came on while driving. AT oil temp, traction control, check engine, and flashing cruise light, she stopped the car, she didn't have anything go wrong just the lights. She googles this before I could do anything, found that it might be the transmission, what should I do?, I told her to shut the car off and wait about 15 minutes and then see if it will go. She did, it ran and the lights went off. When she came home I looked at the car, the lights were not on and I couldn't get it to do it for me. About a week later I was driving the car taking my grandson home, without warning, no hard shift, nothing, just driving on a straight road about 50 MPH, the lights decided to show up. I pulled over, and just sat there with it running, placed it in reverse, no problem, placed it in drive, no problem, lights still on I continued on driving, got my grandson home and visit with my daughter, we talked about the lights on the car. I got in, started it up and the lights were out. I hate to write a book here but, more input the better....right?
Anyways, got home and thought well check the fluid, we have had it for about a year, its got 100k+ miles on it, the fluid was dark but not burnt and just enough red tint to tell that it's tranny fluid.

So I go about the norm, look for fluid, check forums the usual google stuff and the youtube machine, so I continue to drive the car no problems, then on day about a week later visiting some family, I slowed down to turn onto their street and BANG!, it was like I got rear ended, a few seconds later the dash lights up, same as above but it didn't drive any different. Time to go home, we got in the car and headed home it's only a 15 min drive, the lights stayed on and the next day I got my friends scanner and checked for codes, P1017? the common one that everyone seems to be getting. So I do the search here and a few other forums and of course, youtube, boiled down to replacing the valve body.
Yes I bought one new from a dealer, got it for around 7bills, it came in, I installed it last week and went to test drive it and it will not shift out of 1st and I got lights, AT oil temp flashing, flashing cruise, ABS, check engine, and last but not least the traction control light.
Now with all that said... what did I do wrong? I do remember seeing something about the shift position and making sure it's in the right position on the valve body, not sure if it was or not and when I installed it, I did look to at the old one to see where it was placed and I positioned the new one in the same spot....I think....not sure though, but could this be giving me the problem?
thanks in advance.

I would check in over at subaruoutback.org or legacygt.com The transmission is the same in the H6 of these cars, and those folks are much more active.
