Your post is a little misleading. The Lexus have AWD just as the MDX does. The difference lies in the side-to-side vectoring that the Acura is capable of.
Note that 4WD is different as it is typically manually adjustable and in some cases can be turned on and off (AWD shifts back and forth based on need and is automatic).
In ideal conditions, all AWD systems should be rear biased during acceleration as weight is transferred to the rear of the vehicle during launch (physics). Therefore by adding power to the rear wheels, you are able to make the most of the resulting downforce.
All of this is really has no bearing on this thread however as we are discussing the problems with the MDX and it's weak torque converter and the company's failure to properly address the problem.
#726 of 996 Slight jolt while acceleration and decceleration
Dec 02, 2011 (8:22 pm)
I am a new owner of pre-owned Acura MDX 2009. Lately I have felt slight jolt or jerk while slowly starting from red light and while slowing down in a stop n go traffic. Its like feeling when gears are shifting. It happens occasionally. Sometimes in slow traffic, if I take foot off the gas and let vehicle slow on its own, i feel this sudden jerk. Coming from sedan usage for years, not sure what I am feeling should be investigated further. Are you suppose to feel (this slight sudden shock or push) while auto gear change in MDX?

Not sure how old the car is that you are coming from, but newer transmissions seem to be programmed more aggressively.
They have more speeds, and seem to be programmed to mimic a manual transmission... It's especially noticeable during coasting to a stop, without braking..... aggressive downshifting seems to be the norm...
Older cars tend to coast freely, only downshifting to keep the engine from stalling.. It's disconcerting, until you get used to it..

You're describing the full fuel cut technique now being used to conserve fuel. During coastdowns the engine is completely starved of fuel but the transmission is sequentially downshift to keeping the engine turning over.
#729 of 996 2004 2nd Transmission Replacement
Dec 08, 2011 (1:22 pm)
1st one replaced at 76,000 miles under extended warranty and 2nd one just replaced by third party transmission shop at 146,000 miles. In both cases I had little to no warning prior to complete failure. Third party shop replaced the transmission for $3200 and gave me a 3 year, 100k mile warranty. Acura offered to do it for ~$5200 and give me a 3-year, 24k mile warranty.

Bless your 3rd party shop's little heart. What is the name of the 3rd party shop? that seems like a good deal

If you purchased extended warranty and have low mileage why would you have to pay anything more than the deductible?

Sorry this is a bit off-topic for the transmission category -- I have a Lexus and an MDX. When shopping the MDX vs RX350, the Lexus was much more refined (especially the serenity of the cabin). I bought the MDX because it was just right for my needs -- seated more than 5, great for pulling my camping trailer, decent fuel economy, fun to drive. The dealership experience is worth nothing to me -- I maintain and fix my own vehicles -- but if I have to get the transmission replaced before 150,000 miles I wouldn't get another Acura (I'm currently at 58,000 miles with no significant problems ... fingers crossed ... having just done 3 x 3quart synthetic transmission fluid flush and transfer case fluid change).
#733 of 996 Statistics?
Dec 13, 2011 (7:52 pm)
I'm still curious amongst all those with MDX transmission problems ... does anybody have statistics on what percentage of trannys or torque converters fail (either for the pre-2007, the newer generation 2008-2009, or the 6-speed 20010+)? There is a big difference between 5% (1 out of 20 seems very high to me) and 0.5% (1 out of 200 probably isn't bad). Of course that doesn't help you if you're one of the unlucky 200
