Torque converter shutter

Has anyone replaced their torque converter on the truck? I've done everything beside this to find the vibrations in the trucks drive line

 

Your u joints and center bearing are solid?

 

Man dude I've changed everything, don't the new 8" clamshell from ECG and new u joints with hanger bearing and also have a whole new chunk, everything beside the torque converter it's the only thing I have found it could be

 

what kind of driveline shutter do you have? I had a vibration from 25-30mph under light acceleration. When i flushed my trans fluid for fresh, it went away (also i believe i was 1-2 quarts low)

 

Same and I've flushed it twice in 16 months

 

ever find a fix? I have a vibe under load in all gears around 18-2300 rpm I'm fighting that I cant find much info on.

Yea I ended up pulling the tranny putting a HD torque converter

 

Where from, what stall speed?

 

Can you describe a little bit what kind of vibration it was causing? Ive been to a transmission shop and took them for a drive, Been to the dealer and took em for a drive. Trans shop said it didn't seem trans related and I would be wasting my money to tear into it. Dealer said normal engine harmonics and maybe driveline vibes. , some are worse than others. I describe it as almost a hum, or like a cellphone vibrating. I get it around 17-2300 rpms the worst. Has nothing to do with speed or gear, its all influenced by rpm with load on it. Though I get the worst when in D at about 60 mph on a slight incline. Its like a drone sound with vibration just kicks in. I feel it everywhere. Steering wheel, pedals. Floor. My thoughts are it cannot be anything in the drive shaft because its not speed related.. If you shift into another gear, it stops.. Yet the speed and load on the shaft is exactly the same. Only thing changing is the rpms. Now, leave it in that gear, and let the rpms get back into that range, and it starts again. That to me rules out any driveline issues. It has to be engine/transmission related. And the torque converter is what is going to experience the load. I also have a lot of vibes from 3000 rpms and up, but even under no load in neutral. I'm just at a loss with it, on the edge of selling it.

 

I replaced mine due to a shudder at light throttle acceleration

 

Was the shutter seeming to go straight up into the dash and shake the whole dash it self? I am having issues with acceleration at low speed/throttle but not when I punch it, there seems to be no hesitation. If I do encounter the problem then all I have to do is let off the accelerator really quick and then back on and it seems to not have a problem.

Thanks
