Rumble strip sound/feel

Ok I’ve had the rumble strip feel and sound at 39000 miles. I have read it’s more than likely low fluid level in the trans. So I did the process of checking the level and indeed it was low(might have got a total of 8 drips from the hole). My questions are; does this low level cause any damage? And can I add fluid to fix the issue until I can get the fluid changed?

 

Rumble strip feel?

 

Yea supposedly if your converter locks out with a low fluid level it feels like you’re driving over a rumble strip on the side of the hwy

 

Is it constantly while you drive or at a specific speed or RPM?

 

It’s usually between 1500-2k rpms between 2-3 gear.

 

I’m wondering if it’s just the driveline vibration issue that plagues these trucks.

I’ll let someone else chime in.

 

I would almost agree but there’s times the converter kicks off and on and it’s almost like a hard shift. Then a few rare cases it acts like you’ve shifted up in manual truck a lugging it uphill

 

I’m hoping someone else can confirm my suspicions. At any rate the level is still low.

 

Oh yeah if you’re having issues with shifting as well I’d say you need to look at trans fluid.

My truck has the driveline vibe at 2k RPM’s and nowhere else but I have no issues shifting. *knocks on wood*

 

I’m just glad I have that lifetime warranty if it does hurt it I hope yours holds out

 

Nah I did some research on it and conclusions basically came to it being an imbalance somewhere in the drivetrain that doesn’t cause any harm. People spending hundreds of dollars trying to remedy it and it just doesn’t go away really..

Truck is at 169k miles and still kickin.

Hope you figure out your troubles!

 

Sometimes a vibration at a certain rpm could be a u-joint. Happened to my old taco and it drove me nuts until i figured it out

 

I had the same issue. I added this to help with torque converter shudder. Started having the problem around 35,000 miles.

When I did a trans flush/fill at 40k I added this instead of the shutter fix stuff. No problems since, at 60k now.

I understand where y’all are coming from with the vibration thing but mine isn’t just a vibration the rpm’s are going up and down as I’m having the vibration.

 

Was your fluid level low like mine?

 

Yeah def something different. Didn’t mean to derail just brain storming for ya.

 

Does it still vibrate in 4Hi?

 

Much appreciated with the storming.
I have not tried 4hi yet. If it still does it what does that mean?

 

If it goes away then you can join the million others affected by the needle bearing deficiency in the front diff, driver side. Check ECGS for solid replacement. If it is still there, keep searching.

 

My fluid may have just a bit low. Which worked out good as you don't want to over fill if you add additives.
