Just rebuilt my 904 and was adding shift kit mods to the valve body. Instructions indicate a different converter valve spring (photo attached) as my valve matches the 2 plunger style in illustration. Installed the yellow spring per the instructions. It is stiffer but substantially shorter than the one I removed. Does not seem right to me because it does not come in contact with the plunger. Has about 1/8 inch slack between the spring and metal bracket. First, what does the converter valve do? Second, does this seem right? I'm tempted to just put the stock one back on the valve.
