I have a 2000 RCsb 4l80e converted truck and I'm running a Fti triple clutch converter and every time I hit 42-45 my truck goes into lockup and my entire truck shudders. Is everyone's triple clutch converter lockup really this violent?

 

Shouldnt shudder, should just feel like a firm shift.

 

^^^ my yank locks at 40mph and it feels like a firm shift also.
Sounds like something is wrong with the converter

 

Don't get me wrong my PI triple disk locks hard but the trans was built and tuned to do this also.

 

It can shudder... Mine is very firm. Doesn't have to be though.

 

You shouldn't have converter shudder.

 

Not converter shudder... But the whole truck can bang aroind pretty hard if you have the pressure jacked up all the way. The converter lock is harder than my shifts.

 

Just to clarify does the converter lock seem to pulse and shudder or are you simply referring to the converter locking so hard and quick it shakes the truck around?

 

Mine locks so hard the belts chirp.. Because racetruck

 

Mine used to when I was still 6 rib. Not now.
