Also having trouble with a herky jerky transmission
I drive a 2007 Acura TL with an automatic transmission that has ~58K miles on it, and I'm having the exact same transmission shifting problems that CALNEW described above at #36. I have a friend who frequently drives my car, and she's noticed the same shifting problems.
I bought my TL two years ago when she had ~35K miles on her. I noticed the transmission was a bit herky-jerky right from the beginning, but my car-fanatic guy friends told me that that's normal for "an aggressive sports car." Um, okaaaaay. :sqnteek: (Granted, my previous/first car was a Grand Prix, and that car shifted like butter and was able to "coast" without harsh downshifting, so I figured maybe I had just been spoiled.) Anyway, the shifting problem with my TL has only gotten worse with time.
I'm dreading taking her into the dealership, both because of the difficulty you've described, and because when I took my Grand Prix in for a similar problem back in the day, they all but patted me on the head while condescendingly telling me that there was nothing wrong with the car and sending me home without a solution. Less than a year later, Pontiac issued a TSB detailing the exact problem I had complained about (it was due to a bad pressure control solenoid in the transmission.) Anyway, if you fellas think you have a tough time convincing a dealer that an intermittent problem you're describing is real, imagine what it's like for us ladies. :rofl:
My underlying worry is that the transmission problem that was common in the previous generations of TLs is cropping up in our generation, despite Acura's insistence that they had finally fixed it. I bought my TL as a certified pre-owned, so thankfully my power-train warranty runs through 100K miles, but judging from the way my car handles and what I'm reading online, it looks like I'll be trading her in before the 100K mark just to be on the safe side. It's a damn shame, because I love my car otherwise, and a huge part of the reason I chose the TL over the competition is the car's superior reliability ratings.
Anyway, I'll check back in after I visit the dealer. Here's hoping they don't give me a hard time! I plan on printing out relevant forum discussions to illustrate that I'm not the only person having this problem. In the meantime, if anyone has had any luck fixing this issue, please chime in!
