Hi all,

I have a 2001 blazer 4x4 and am having a slight issue. Once the car is up to temp and I am traveling above 45 mph and left off the throttle to stop accelerating the car will shutter. The rpms remain steady when this happens. My theory is that the torque converter is stuck locked and the stutter is when it comes unlocked. I also notice it when I begin to go down a hill.

Looking for any suggestions or other theories as to what is going on.

Thanks in advance for any suggestions!

 

How many miles do you have on the transmission..Whens the last time you had the transmission serviced?The torque converter locks up into overdrive usually around 50 mph.When this happens the rpm`s will decrease.If the converter is locking and unlocking, the rpm`s will not remain steady, it fluctuate up and down.

 

I have 160000 miles on it and did a transmission flush at 100k. I just checked the fluid right before posting and fluid is still pink and smells normal and is at the appropriate operating level.

 

Check engine mounts tranny mounts etc.
