what is the shuddering noise from the tranny when it goes into overdrive ?
is it tc slipping or do i need more pressure via new valve body ?
thanks

 

I aint much of an auto tranny guy but we have a few around here that can prolly help you

please fill out yer signature so we can get the full picture on yer truck

 

do you feel the shuddering when during the 3-4 shift or only when the TC locks? if you're trans is stock and it's only happening at TC lock-up you may be able to get buy with a quality aftermarket TC. there are TC's out there with 1 clutch or as many as 5 clutches. what you need will depend on your mods and typical use. as whit said, please fill out your sig as it may help us help you

 

thanks for you replies and i think i will just go ahead and get a single disc tc
