I2007 acura mdx will not shift into 5th gear.

Have the codes read. Probably bad clutches inside the transmission. Once the computer see's them slipping a bit, it pops a codes. The longer you do this, the more it will cost down the road.

I have Acura 2003 3.2 TL, its Malfunction indicator light is blinking... suddenly stopped on way and when restarted... it started...possible causes?

Blinking check engine lights usually indicate the problem is severe enough that it could be doing damage to the catalytic converter. Typically engine misfires will cause this to happen. Check to see what codes caused the light to come on. Post them here and I'll be happy to help you further

Ok, my 2000 acura 3.2 tl egine light blinks and the tcs light stays on, also the engine has a slight shake at idle. Took to autozone to get the codes came back as all 6 cylinders misfire, multiple misfire,...

This is strange. The tcs is a traction controll error. If you are getting misfire codes and traction control warnings, then I would have your control module tested to make sure it is not having intermittent power issues to each component.

Possible issues with the engine light coming on in my 2003 Acura TL if it is still running great?

Stop by local Autozone,Advance or any good auto parts store and have them do a FREE fault scan. It could be as simple as glitch due to cold weather, a stall, etc. Your OB tracks all functions and might be something that happened only once but enough to trigger sensor. It could also be early warning of part failure. When they do the scan, they come out to your car,plug in and read codes. They can print out the codes for you and reset your lights - FREE

When the Check Engine warning light has been reported on, turn the ignition on, pull down the passenger's side carpet from under the dashboard and observe the LED on the top of the ECU. The LED indicates a system failure code by blinking frequency. The ECU LED can indicate any number of simultaneous component problems by blinking separate codes, one after another. Problem codes 1 through 9 are indicated by individual short blinks. Problem codes 10 through 43 are indicated by a series of long and short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the problem code.
