"Drag" feeling at 40mph and 20mph? by cobains
Oct 07, 2008 (6:32 pm)

Hello all!
 
Just bought a base '08 MDX (after eyeing one and constantly thinking about for over a year) a couple of weeks ago and I try to "hypermile" whenever I can.
 
It seems that when I am coasting to a light, the car seems to have a "dragging" feeling (like brakes are being applied) when I am coasting down to around 40mph. It seems to happen again around 20mph.
 
Am I just being paranoid or is this normal from the automatic transmission?
 
Any comfort/advice is appreciated

I noticed the samething when I got my 08 Sport/Ent. MDX. Watch the tach when you feel the drag. The vehicle is actually down shifting to a lower gear. I thought that was pretty cool and it actually helps out by saving your brake pads.

I had a smiliar problem but the car was a bit older. The steering wheel would shake significantly when applying the brakes at 55+ mph.
 
As it turned out, one dealer told me they replaced the rotors. They lied. They resurfaced them. All other dealers went off the assumption the rotors were new.
 
What happened was the resurfacing was not done properly, which was causing the shaking. The fix: brand new brakes and rotors on the car.
 
You should contact Acura Client Care (I think it's in your owners manual) and tell them the problem. They will get you in touch with the right people. For me, they even contacted the dealership they felt was the best and made all the arrangements. I got excellent care and the car was finally fixed.

Unfortunately, yes. Transmission had to be replaced, cost me $1200, but after that the car is running fine. Other people reporting that the problem was caused by one of the 2 control valves - I don't remember which ones. Sorry I can't be of more help

Thanks for the reply. Let me vent a little.
 
My transmission has been very good from new up to 117k miles when 3rd gear went. Acura dealer said save money and go to AAMCO so I took it to a local AAMCO dealer who identified internal problem. The took apart and found third gear bad. replaced third gear clutch plates and the piston. Replaced a pressure valve and re assembled with typical rebuild kit and a rebuilt torque converter. Cost me 2700.00. Right away I noted hard shifting etc but opted to hold off since I had to take it back for 10day check up. But within a couple of days i noted the tach jumping 100 rpms and then a loud vibration noise that sounded like going over grate in the road. This showed up when the tack was jumping but only some of the time.
 Well long and the short I took it back to them 6 times and they rebuilt it 2 additional times and replaced the linear solenoids and the torque converter lock up solenoid at additional Charge on other visits, Now up over 3400. They even had me take it to acura to have them put on diagnostic computer and they even paid the bill.
Acura said a bad valve or the torque converter. On the last rebuilt the AAMCO tech found the torque converter lock up valve was sticking a little so he honed it. Got car back and noted tach still jumping but no sound. But a few days later the sound showed up again but very faint.
 
AAMCO is trying to tell me it is engine problem eventhough Acura ruled that out.
I am now going through Credit Card charge dispute process in an attempt to get my money back. Dont believe they should get unlimited attempts to fix the problem that I believe they caused by initial faulty repair.
 
Anyhow the problem I have occurres like this.
 
Cold start up, drive for about 10min, house to freeway. Get on I-4 and head to work and the tach starts the jumping within a few min. and the noise is there but faint. It usualy goes away after about 5-10 miles of travel. However since it was cold this AM 65 degrees (cold to me in FL) it lasted the whole trip. Usualy the pulsing goes away after all castings are good and hot and possibly since ambient temp was lower than it has been the problem presisted until I got to work, about a 16 mile drive.

I know I'm jinxing myself here but has anyone had to replace the tranny on their '04 MDX? I've read lots of problems with earlier models and so far (57k miles) have not had any issues.
