As stated above, the hydramatic was used in the duece and a half military truck (korean vintage). The automatics were so bad that most of the ones around here (still running) have Clark manuals put in them. There is a company making a full manual valvebody for them but in the end it is too much money for very little gain. The ONLY reason to use the automatic in the military trucks is the fact that the low range is in the tailshaft of the tranny, not the transfer case. Buffalo Ent. advertises a STEEL adaptor plate and custom flexplates to do a conversion to the later automatic. This should also allow you to use later model transmissions with appropriate bellhousing. I'd like to see some adventurous soul try a new venture five speed.
