I have a TTA. Just had the tranny rebuilt, when I first got it out of shop it shift perfect. About 2-3 months later, it stopped shifting at WOT. I dont have a rev limiter so, I pretty much screwed up motor(strecthed timing chain). Took it back to shop, they thought it was the band, changed that nothing. But it shifts fine at mild to normal acceleration. But I get on it, I have to let off to shift, if Not I'll peg the tach. Any Ideas and info really appreciated.
