Transmission stutters when vehicle comes to a halt

Pumping the gas pedal doesn't do anything. the fuel is computer controlled. Find another mechanic.

On some vehicles the computer module will lose the memory it has (which was backed up by the battery) for engine operating conditions like idle and transmission shift speeds and possibly other patterns like typical driver patterns for acceleration, etc. These patterns are lost while the battery is disconnected, but after some driving time with varying driving scenarios the computer relearns the patterns and the problem is corrected. Check with a Mazda dealer to see if the 2005 is affected like this.

It sounds to me like a passing gear issue. Or even and Over Drive issue. Try this to find out. When you put the car in gear, instead of O/D, try regular drive. If you have a push button O/D then deactivate it. If you only have Drive, then try shifting into 3. Run the car up to the same speeds you were having problems with. If you don't have the issues with the higher RPM's then it is an Overdrive/Highway gear issue. If it still stutters, then it could be a fuel delivery issue. Good luck.

Hello
The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Well I am not a mechanic, but I am fairly handy with a wrench. My initial suspect would be some sort of transmission issue whether it be mechanical or sensor related.Is it more noticeable when accelerating slowly vs. a quick acceleration? That could mean a torque converter. When is the last time that you had the transmission fluid changed? A good shop should be able to rule out many issues by looking at the fluid that comes out (looking for metal shavings and the like). Taking your car to a transmission specialist may be your next viable option. Hope this helps

You have a blinking battery light
and a condition when pedal is pressed
to the floor

Diagnose those 2 issues first & maybe you
will resolve the stutter problem
Most likely ignition issue

Try a different mechanic

The fact you tell use what your experiencing,
is proof that your mechanic isn't working
on the issues you have.

i would hazard a guess and say the ECU has packed up on you and its been going down for a while

YOU MAY HAVE A BAD U JOINT.

p1677 code on ssangyong stavic 2.7l turbo diesel. Engine light comes on and vehicle loses all power and coasts to a halt. Also has 3 open circuit glow plug codes.

have the egr valve checked
