if yall don't already know, i blew my tranny after i installed my 3k stall. so i brought it to a local tranny shop and had them remove, rebuild, and install the trans with the 3k stall. this thing is freaking awsome. it fries my 20's for nothing and the shifts are great. the only thing i noticed is that when it comes into lockup around 45mph + or - 5mph, and i stay at that speed, i get a vibration comming from the trans or converter. is this called "shudder" from the converter/trans? help me out. opinions welcome. thanks guys...

 

If you can't get it to vibrate with trans in neutral and bringing up the rpm chances are it isn't in the verter. could be a shudder from new clutch in verter. if you have the ability turn off the tcc lock and test drive it.

 

it revs up good in neutral, no vibe. i'm pretty sure it's the verter b/c i remember someone a few months back saying they had this problem. i don't have the ability to tune it. only my nelson tune and it is tuned for everything i got

 

Just a guess and this mayy be way off but have you checked to see if the converter bolts werent loose?

 

I know what your talking about and mine does the same thing. I think it is the converter lockup also. Does it do it a wot? Sounds almost like a peace of sheetmetal vibrating.

 

Could be the converter or the driveshaft. Take the bolts out of the converter and rotate it to the next hole and see if that works. If not do the same with the drive shaft, rotate it 180 degrees.
