Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

NHTSA — Power Train: Automatic Transmission Problems

2001 Acura CL (Page 1 of 9) Notes: The automatic transmission on the 2nd generation CL (2001-2003) is a downshifting mess. According to reports it slips, flares, and eventually fails --- sometimes around 40,000 miles.

The troubled transmission got an extended warranty for some CL owners that was later extended even further thanks to a class-action lawsuit in the United States. But even with the extended warranty, the transmission in this car is well known for overheating and locking up suddenly and without warning.

I have had 2 transmissions replaced and my 3rd transmission is failing as well. I have gone through Acura to see if they could goodwill the transmission since I am a victim of thier faulty transmission recall. They refused to replace my transmission and told me it would be $5,100 to replace. I feel that this is not my fault as they have engineered a defective transmission that has reulted in deaths and serious accidents. I was just out side the 3yr/36,000 mile warranty and the would not help. As a member of our armed services I feel I am being treated very unfairly and I fear for my life every time I get into my vehicle. I am not able to pay this kind of money to replace there problem.

Check engine due to transmission problem. A lock up occur due to a problem in the solenoid in the transmission. This car had a recall before for the transmission. It was replaced, however. It has new issue. Many people suffer from this problem.

CL 6-cyl

  • 58,300 miles
Purchased 2001 Acura 3.2 Cl type-S (replacing my first Acura 3.2cl that was totaled in a 1/2009 crash) on 3/2009 as second owner from Acura dealership with 35,232 miles. Got all service records for this automobile from dealer including the record dated 9/9/04 (mileage 14,660) for the installation of the oil jet kit during transmission recall. While driving home on the highway this evening, the engine and vehicle stability assist (vsa) system lights came on and stayed on. When I finally stopped at a light and then processed through it at a normal slow speed, the tachometer jumped from 2,000 to 4,000 rpms while in first gear. Luckily, I was within a few blocks of my destination. When I returned to vehicle to drive home, car would not shift out of first gear. I had to park the car on a city street that same night. I hadn't experienced any transmission problems until this one night. Had car towed to my regular mechanic the next day only to be told it was a transmission problem. Contacted local Acura dealer to be told that my vehicle was out of the warranty period and they tentatively offered a good will split of the cost. (I had bought my first new 2001 Acura 3.2cl from them and they had installed a new transmission during the earlier recall.) had vehicle towed to a nationwide transmission specialist shop. They determined that transmission had to be completely overhauled. Agreed to have it repaired and they used new factory parts and Honda genuine automatic transmission fluid (atf-Z1). After completion and payment, I was advised to drain and refill fluid every 15,000 miles and flush transmission system using atf-Z1 every 30,000 miles. I had never been told this transmission servicing schedule by my original local Acura service department consultants. Owner manual states changing the fluid at 45,000 miles or 36 months in their maintenance schedule for driving in normal conditions. Vehicle had 58,300 miles when this problem occurred.

I have a 2001 Acura 3.2 Cl just days before my birthday the transmission started to slip I took it to Acura dealer and they informed me that the transmission will have to be replaced at owners expense ($4800) and they also informed me that no goodwill gesture will be exercised because vehicle is out of warranty I am the 2nd owner of this car since late 08 and had no idea of the issues I am still paying for the car and it is my only transportation. I do not know how I will be able to afford both the car and transmission and there is no way for me to sell it this car not only nearly killed me but is now draining me financially (due to Acura not replacing a clearly faulty transmission) and I am now stuck not being able to work and could lose my job this is a huge problem for me I even had to quit school!!!

While driving my 2001 Acura Cl type S to work (about 10 miles) my car would not go above 45 mph, then only 30 mph, but was able to make it into the parking lot. An hour later wanted to take the car to an auto shop and all seemed normal until about 6 miles after when the car would no longer move (engine still running ok). Tried all gears but to no avail. Let the car sit for 10 minutes and car worked ok again and was able to drive it to the auto repair shop. The next day they called and stated the transmission is "shot". all clutches are bad. They installed a jasper remanufactured transmission. I was told that Acura only used this transmission type for the 2001 model. It was the first year for that transmission and the last year. I assume there were a lot of problems with it and Acura went to a different transmission for the 2002 model year. It cost me $4500 to replace the transmission. I had about 102,000 miles on the car at the time of this failure. Note: There was a recall on the transmission from Acura and I did bring the car back to Acura for the recall notice.

2001 Acura Cls (VIN [xxx]). when pulling out onto a major road (55mph) with oncoming traffic the car paused as the trans slipped, the engine revved to 5000 RPM, the trans then locked into gear, the tires squealed and the car lurched forward. Thank god that my wife didn't run into someone or lose control of the vehicle. Now I read that this is common with this model year and transmission. The NHTSA knew of the problem and a class action settlement was offered. However nothing was done to make owners and the general public safer. It seems to me that at a minimum the NHTSA should have mandated Acura to warn owners, and mandate Acura to perform more routine inspections on this poorly designed transmission, and perhaps more frequent fluid changes. I read that the NHTSA was considering additional action on this issue and hope you do. This incident occurred with no prior warning. Allowing a 240 hp car on the road with this type of known failure is unsafe to owners and the general public in my view. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I have a 2001 Acura Cl-S, having severe problems with the transmission. There was a recall, but they say it is out of warranty, by time. Problem is when I bought the car 2 years ago I brought this to someone's attention at Acura, and was pushed away as if I knew nothing, and now they want to charge me close to $5000 to replace the transmission.

Now on 3rd transmission. 2nd owner replaced under warranty about 9 mos. Prior to my purchase (I am 3rd owner). Transmission blew about 1 year after I purchased the car and I purchased new transmission through Acura who offered absolutely no assistance even though this is a known defect. When the transmission failed, we were traveling on a highway at approx. 65 mph and car violently downshifted, nearly causing loss of control of the vehicle. Acura is not taking responsibility for these transmissions. The transmission that the 2nd owner had put in was a transmission that supposedly had been manufactured to correct the known problem. Obviously not, since the thing blew with only 77K miles on it! 152K miles on this car and 3 transmissions. Ridiculous.

I purchased new, a 2001 Acura Cls, and gave it to my mother, about year later in 2002. At only 39,620 miles the transmission started to severely slip, and required towing to the Acura dealership, where, at a cost of $5,076.66, required replacing the complete transmission and ECU. The dealer service department associate could explain specifically what caused this damage.
