Question about 2003 Mitsubishi Montero

1 Answer

Engine shudders at 35-40.

While accellerating, the engine shudders between 35 and 40 mph. It doesn't feel like its between or changing gears, and doesn't happen while decellerating. Kind of feels like when you're on the highway and you go over those don't-fall-asleep bumps on the side of the road. Any help would be greatly appreciated.

Hi,

Appreciate the direct "Ask Me".

Initially
, what comes to mind is probable faulty universal joints (U-joint), actually two of them and/or missing retainer clips. They would be coupling the transmission to the propeller shaft and then to the differential. The power train is nearly perfectly balance system and any missing needle bearing on any of the four ends of the U-joint wold cause a slight wobble on a particular speed. To check, the vehicle must be lifted and the propeller shaft yanked. There must be no noticeable play or slack.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

2010 Jeep Wrangler unlimited sport extreme shudder at 40 mph- if I press the gas-pedal and get the RPMs to rev, the shudder ceases, only to return once I am back down around 38 mph-41mph.


which engine the 3.6? v6?
that shudder is called MISFIRE.
get a tune up yet, even $1.49 spark plugs?
no its not the trans,
if it dont slip, its not trans, (see RPM races? that is slip or too low gear)
if it shifting to the right gears, its not the trans can you count them?
is the CEL lamp glowing or flashing driving, is yes, that means
scan me now. in fact scanning while it shudders, is like (magic)
why start guessing, do a tuneup,
then scan it.
if its is misfire the PCM will tell you what cylinder misfires.

are your spark plugs 6 years old, if yes, why?
going for 200k miles on them.?

Why does my truck shudder when shifting into a higher gear with manual transmission 83 F100 Straight Six


not knowing the quality of workmanship used in the engine rebuild, it is difficult to answer exactly what is wrong
plugs and leads will not be faulty
I think the clue is in the remark about the carby being replaced and it ran a bit better
that indicates ,along with the very rich settings, that it could be an valve timing problem
I suspect that the cam shaft lobes are damaged or the timing chain gear is loose on the cam shaft
running well in the beginning and then slowly failing all points to the cam shaft lobes, cam followers or loose cam gear

Well, you did a really good job of describing the symptoms, but you didn't do so well describing the car. Are we talking about an automatic or standard transmission? are we talking about a four or six cylinder engine? You are asking about a drivetrain problem without giving any information about what drivetrain the vehicle is equipped with.

With all that said, IF we are talking about an automatic transmission being pushed by a V-6 engine, then there is a Technical Service Bulletin (TSB) that matches the symptoms you are describing. In this case, the problem is most likely being caused by a deformed or damaged exhaust pipe "A" mounting bracket.

Inspect the rubber bracket for cracks or torn rubber. If the bracket is damaged replace the bracket. Bend the stud on the exhaust pipe if necessary to get the stud to go through the bracket as straight as possible so the stud does not "ground" against the sides of the bracket. (see diagram)

1994 Buick Regal "shudders" while driving/ won't always up-shift


It is a 24 year old vehicle (made in 94), it probably needs to retire :>)

Take it to a transmission specialist rather than a normal garage, as it sounds like a sensor problem. It may also be rubber mountings that have perished, and the engine and transmission are only partially mounted to the chassis.
