Are they not the same?
Texas Speed lists some of the low end stuff like TCI, but they also sell good stuff like Circle D and Yank.
for the 4L60E,jegs stocks B&M and Hughes as Summit stocks TCI,
if you're after a performance convertor,those 3 brands(along with many others probably)are to be avoided. a good performance convertor should be custom made. I've had TCI and Hughes and now running a Yank SS3600.Yank and CircleD can provide convertors that'll 'wake' your car up and let the 'beast' out.
“There is nothing in the world that some man cannot make a little worse and sell a little cheaper, and he who considers price only is that man's lawful prey.”
And "prey" is the critical word here.
