Cliff, it doesn't actually slip in first gear (once the vacuum line was reattached), it's more like a chattering or hesitation then a slipping. It's definetly in the drivetrain and not in the motor. The chattering only occurs with the shifter in the 'His' side of the Hurst dualgate (which doesn't really make any sense because the tranny gear selector is positioned the same as in the 'Her' side of the shifter. Plus, as mentioned previously, the tranny is designed to remain in low gear as long as the shifter is held in low. However, now when the 'His' side is selected, it shifts out of first by itself.
