Am I correct (I've never seen one in person)? I guess the transmission was a stock TH 400 with a different valve body. Did the TH 400s that went into the Hurst have upgraded internals?
Just curious.  |
The transmission cooler was a regularly available option on any auto-trans car. It is pretty rare, but not H/O specific.
The 68 and 69 H/O did get specific transmissions. The 68 got a modified 'OW' code TH400 (from the 68 W-30) with one fewer intermediate clutch plate and a different governor and valve body. There is no special code for this trans. For 69, they got their own transmission code, an 'OH'. This actually started out as a full-size car transmission (long shaft) and had quite a few parts changed out, but nothing truly exotic.
There is only a single cable going from the dual-gate shifter to the transmission so there is no difference in how the transmission works based on which shifter "gate" you use. There has always seemed to be a lot of confusion on that with some people thinking that using the ratched-gate side of the shifter gave you something like full manual transmission control. Unfortunately, not true.
