Damn bro! Mine shifts at about 4200 at WOT.
Really? Stock, my '88 7004r would shift at 4800-4900 or so... after the rebuild it will shift at about 5100. It downshifts easier now too. So if your putting along at about 25mph and punch it, that sucker kicks down and flat out scoots.
The th350's have no trouble winding out. The th400's shift too soon for my tastes, especially the Burb. There's no tach, but I think it shifts at about 4K, lol.
