Had a lockup issue with my PT4000. o-ring was messed up inside. Sent it to them and they had it in/out quick and took care of me! Works great now and having lockup with that killer converter is awesome now. Thanks for the free shirt also.

 

Great to hear you have lockup now,Should be a world of difference on gas

 

All 3 of my converters have been Yank. Nothing else will do.

 

I've had three awesome Yanks also. Can't beat 'em .
