Question about 2002 Acura MDX

1 Answer

Transmission lugs in D5 gear at low speed, low RPM.

2002 Acura MDX, 105K miles, Operating in D5 at low speed (15-25 mph), the vehicle doesn't appear to know what gear to go in. It shifts up/down/up/down and has a lugging type sound. Some vibrating. If I put in D4, it operates fine, however, it does appear to be shifting hard. The shop says I need new transmission at $4400 CDN. My brother, who is a heavy-duty mechanic feels it could be a shift sensor or something electronic.

The auto parts stores cary a special kit for removing these wear eye protection and if you have air tools it will make it much easier. don't use sockets not rated for air tools (they break and will hurt you)

SOURCE: Why is my 1994 Chevy S10 Blazer lugging?

Could be vacuum leak or bad ignition wire(s).

I had a similar problem on my "93 Ford probe. The engine idled pretty rough with shakes, Turned out to be a head gasket leaking engine coolant into the cylinder during low rpm's. At fast rpm's it was fine becuase the internal cylinder pressure was greater than the hot coolant pressure & would prevent the coolant from leaking in.

A friend has the same problem with his "94 Blazer 4.3 L, throttle body injection, manual tranny. He hasn't fixed it yet, It started a few weeks ago & is getting worse. His gets a fast idle with hiccups which causes the engine shake. He already checked the EGR valve. He also has a severe exhaust problem, Not oilly but very gray & terrible smelly, but only when the fast idle problem happens. THis fast idle hiccup problem starts when the engine is warmed up.

SOURCE: lug pattern for 1999 Chevy Malibu

the lug pattern should be 5x100mm, you having the loaded malibu it could be the 5x125mm. if you still have the factory aluminum wheels on there then you can either take one off and look on the back of the wheel you will have to look closely it will tell you though, or you can go to www. tirerack.com there website will navigate you through and give you the proper size. hope this helps. sorry not more specific.

The trani is electronically controlled. without a diagnostic computer you are not going to know. It may be the speed sensors (for the trani.) but thats a guess. how long since the last trani service. Fluid level and condition can affect its perfomance. Good luck.

I put my car in drive and will not move why?


it can only be 2 things.
1: transmission slip
2: engine died, or has weak power.

if you know what engine rpm is, you can solve this riddle.
A: RPM RISES FAST, MPH (SPEED) DONT. BAD TRANNY
B: Rpm sicks low, car dont move, bad engine (weak, or 100 other reasons. but (bad engine power)

it be impossible for me to express RPM with sounds,
so only an RPM gauge works. does your car have one.? "dash"?
im too lazy to look but, most cars have sub models that dont have this
important gauge.

RPM shot up to 4.5/5 while idling


I have a 2003 Acura TLS, bought new Oct 2002 currently with only 42600 KM (real low) My problem appears to be the same. I noticed specificly on warm days after 30 min driving, when coming to a stop, the idle was about 3500 RPM. Parked the car, turned it off. When starting up again, RPM stayed at 3200, also couldn't put into drive (possibly safety mechanism to prevent damage to transmission). After 30 min when cooled, was able to start again - OK.
I brought it to the dealer thinking possibly connected to FAULTY TRANSMISSION". There was a special extended warranty issued by ACURA >>> http://www.internetautoguide.com/auto-recalls/09-int/2003/acura/tl/index.html I believe it also includes 2002's. Your Dealer should check into it again.
My dealer, ACURA LAVAL (in Que, Canada) seemed to look at nothing else than the transmission. In fact, 2 days after not hearing from him, he told me that they had already ordered a NEW Transmission which is being put in as I write.

Hope this is helpful to any Owner/Dealer who reads this

Stick shift # Automatic RPM


That is normal,If you do the same speed in 4th gear the rpm's will almost double.

The rpm's will repond faster in a manual than an automatic.

In a manual the engine supplies the power required directly to the gear that you have selected thus the engine rpm's will increase or decrease as needed.
