#2 of 34 2001 Aurora Transmission hard shifts
Oct 08, 2007 (11:30 am)
I have recently purchased a 2001 3.5 Aurora, and was advised by the previous owner that the transmission occasionally had bouts of rough shifting. I experienced this today, and it is like popping the clutch between gears. Even shifing from Park to drive, the power train "clunks". Shifts occur where they are supposed to, but there is no cushion. I'm told that turning off the engine and restarting usually solved the problem in the past. We'll see.
Can anyone point me in the right direction? Past inquiries at the garage came up empty, says the prior owner.
#3 of 34 Any clue to this problem?

Driving my '98 Aurora (140K miles) at about 80 when I feel a slight "clunk". 15 seconds later, a HUGE "clunk" (felt like I hit something). I immediately pull over, but as I'm slowing, the engine is missing and there is some jerking deceleration. As I coast the last few feet in neutral, the car jerks to a stop - I never touched the brakes. I managed to 'baby' it off the freeway, but it was stuck in 4th gear. Got it into a gas station. Checked the tranny fluid (engine running) and it was surging up & down in the filler neck. Engine was idling all over the place too from 500 up to 1500 rpm. Tried reverse - no reverse. Only forward in 4th. The tow home cost $300. Next day I check trans fluid again, and it's empty. Put some in, started her up, put her in gear and she dropped smoothly into 1st. Tried reverse, it worked. BUT, just coasting in neutral in the driveway, I kept feeling these "grabs" like someone stepping on the brakes. At one point, the car would not move in neutral. Got out & tried to push, and could not. It will go in gear, but feels like something is hanging up in the tranny. Any guesses? Love this car, but I'm done with the majot repairs.

To the 1995 and 1998 aurora owners with tranny issues.
I have a 1998 Aurora with 175000kms on it. My tranny went at 75,000. I started it on the garage pad, heard a large noise and stopped the car. I started it later and everything seemed fine, One week later, the gears all went. Maybe there was a weakness in the tranny--I do not know.
I checked with various tranny rebuilders and they told me that since it is a cadillac tranny, the costs of rebuilding could cost more that getting one from GM. I got a new tranny with 80,000 Kms warranty. The new tranny still runs as smoothly and perfectly as a tranny can ---as does my entire 1998 Aurora, which I intend to keep for many years. I just bought myself a 2008 Solstice GXP as a fun roadster car since e I could not find an adequate replacement for the Aurora---so now I have 2, which is silly, but fun!!!.

Johnnyboy, how much did that cost? I've heard upwards of $3000. I love my Aurora so much I am tempted to go for it against the protests of my friends and family ("good money after bad...."). Easy for them to say (they all drive premium leased cars). Until you have owned and driven an Aurora, you don't know what falling in love with a car really is.

I had the exact same issue. It is in the shop currently and I am waiting on them to take a look at it. They are going to drop the transmission to look. ($225). The codes indicated the speed sensor was not functioning properly... that makes the pressure go up.. the result is the hard shifting. I will know more tomorrow.

Thanks, Hilltopperdad, for the update. I've had this problem occur twice since taking possession of the car in October. Please let me know whart you find out. The previous owner said he'd had it in the garage, but not faults were detected.
I really like the car, and am glad that I purchased it. If this can be resolved without too much pain it will really be a joy.

$2,700 sounds pretty reasonable on a rebuild for this car. I've had more luck using private transmission shops versus national chains over the years (decades), referred by folks who drive cars cradle to grave like I do. Funny how the tranny problems in my fleet faded when the teens were out of the house and driving their own cars.
The shop I use now was recommended by a friend who drives high end cars and puts a ton of miles on them. When he developed a serious tranny problem, he took his Acura back to his regular local dealer of many years/cars, got quoted $5,400, flipped out, went transmission shop shopping, and wound up at one that did the same job for over 35% less. No follow up issues, and that same car soldiers on five years later.
When I pulled up to the same transmission shop (located in a lower rent industrialized area of town), I saw Acuras parked there. When I asked the owner what all the Acuras were doing there, he said he does that same dealer's overflow.
I like the idea of getting the same level of quality without getting ripped off. Ask your more knowledgeable friends and acquaintances, and shop around.
