Did TH400 trannies ever come with T-handle shifters in any Firebirds?
Yes, the 67 400/400 has a T handle for the automatic. As far as I know the handles were the same for all 67 automatics ( T handle with the “button” above/inside the T). In 68 they went to a T handle with the “button” that sort-off wraps around the top and sides for the automatic. In 69 the THM-equipped went to the new simulated walnut knob round knob with the button on top (Knob shaped like the new real walnut knob available in the manual floor shift) and a T-handle ONLY for the 2-speed automatic. Keep in mind this was a new shifter for the automatics, with the ability to speed-shift without skipping up past the next gear. Sort of a poor-man’s Dual-Gate. Just lean the knob to your right, and when you push it to the next gear, it stops in a detent at the next position. The differences were in the linkage mechanism and not in the handles (for the different types of automatics). All years had the early “bird” emblem in the pushbutton style.
