I looked through the parts book. Very few parts are listed for the illusive WT 4 speed. One of the few parts that I find is a 476041 shift lever which includes a reverse latch. So I guess that seems to rule out the 1935 WT 4 speed. A little more research in the 1953 edition of the Hollander indicates that the WT was actually a 4 speed Warner transmission used in trucks up to 1 1/2 ton. The Warner case is certainly much different than the GM "Peanut transmission".
