Easy Shifting for the Dewalt Transmissions?

In addition, your cutting ofthe white and yellow plastic cases may be out of square. If you tighten the 6-32 screws to seat the transmission end against the mount plate, you are probably distorting the case. To solve that problem, we make a ring that takes the place of the internal ring gear that you remove with the first stage. It's length sets the sun gear pinion to the correct depth for proper engagement, and squares up the whole assembly axially. The ring OD is equal to the internal Diam. of the white case and seats against the internal transmission shoulder, and the ID is about.010" larger than the OD of the "Top Hat" to help retain internal grease. The ring thickness is about .310". This ring then seats into a .020" counterbore we machine into the CIM mounting plate. With this arrangement, you don't depend on the edges of the transmission case to square things up.
PS: We reinforce the 1/16" shifter rod with a 1/8" roll pin so when the servo pushes the shifter arm, it won't bend. The roll pin has an internal diameter of about 1/16", so the rod will fit right through, and will be extremely stiff. Hope this helps. We have used these transmissions for several years, and have not had one failure. PM me if you need any more help.

This 2nd post was done to correct the "white" transmission case color, instead of yellow

Thanks everyone for your help. We experimented a little more with what you guys said and we did get it fixed! Thanks for all of your help and we hope to see you guys at competition.

What did y'all end up doing to get it fixed, out of curiosity? That might help some folks down the line who run into similar problems.
