Re: Another Transmission thing, 2008 XR
Well I never had transmission down shifting problems, it always down shifted easily, maybe too easily. The 6 speed tranny is maybe too many gears, or engine is under powered. It wasn't a smooth downshift but I wouldn't consider it as hard. I had my mechanic perform a transtech fluid change around 100k.
The 3-5-R went around 128K. The only symptom I had was that I started out at a stop and it wasn't in 1st gear, it seemed as if it was in 3rd or 4th as well as it had no reverse. It was driveable, but I was across the river and didn't want to drive risk a breakdown going across the GW bridge to home. I had it towed to a shop, it drove off the flatbed in reverse, no problem and seemed like there were no problems. The mechanic hooked up his transmission code scanner and the only code was a mismatch gear ratio kind of thing, he test drove it, cleared the code and sent me on my way.
I drove it home and continued to drive with no problems for a two or three weeks, while doing some research on reputable rebuild shops and replacement options. While I was doing some research I came across some comments from dealerships about how they treat Lambda owners. Some comments I read about are as they joke, "Has your wave plate gone yet?" Just the kind of compassion you need from some business where you spend $36,000. Most dealership mechanics work on a flat rate, so they usually get a set number of hours for a particular job. The mechanic can actually loose out on money by taking on a transmission job. A guy at work has a brother who is a Honda mechanic. He says they must take turns on transmission rebuilds so one guy doesn't loose out all the time. Just the kind of expertise you want, Russian roulette transmission rebuilds. Some dealerships send out their rebuilds to a transmission shop. This is the kind of mechanic you want, an expert.
I took it to an independent shop where they had just rebuilt a Traverse, he showed me the failed plate. I knew this shop was the place to have it rebuilt since he already did a few. The most important procedure is to hot flush all the remaining metal particles, several times if needed. Since then I had two other transmissions rebuilt here so I do trust them.
After I paid $3500 for my rebuild, GM came up with extended coverage to 10 years and 120k on the 3-5-R problem. I applied for reimbursement and they sent me a check, before it cleared, they stopped payment on it since I was 8K over, just my luck.
So how many miles do you have? You should be covered with the 120k special program.
I also read that they can replace the plate before it fails and not have to remove the transmission, they just take the case apart in place, This saves a lot of labor and costs about half of a rebuild. Well I have over 185K and it runs great, I am hoping to put on another 100K.
