Always go for the stronger, World Class (WC) T-5 boxes. A quick way to spot a WC trans is this cluster gear cover with the step, as opposed to being smooth. The best way to identify any T-5 is to reference the tag number. We found four Camaro V8 T-5 WC codes: 1352-195, -196, -212, and -213 (used only in ’92 and ’93). These numbers can be found on transmission tags, not on the case.
