I've had it for 2 months and only get to mess with it a few hours a week right now so its taking me awhile to learn all the the stuff on it. Its a 78 model with power shift tranny. I keep saying I'll get the manuals next week. Anyway, on my Ford tractor the hydrolic fluid and tranny fluid are the same with the same resivour. I discovered yesterday that on the D31S its different (I think). Below are pics of 2 dip stick tubes in front of the seat. They are very close together and one stick is flat and the other stick is round. I'm wondering if one is tranny fluid and the other final drive fluid. The hydrolic fluid is under the right arm rest. Does anyone have an idea what they are and what fluids s/b used?
In the close up pic you can see the shifting/valve body plungers at the bottom of the fluid tubes. The plunger on the left (right side of D31) is all the way in for reverse and out for forward (or maybe vis versa). The one on the right is the gear plunger and selects 1st, 2nd, or 3rd gear. The gear plunger moves in and out about the same amount as the f/r plunger but I only have 2 speeds instead of 3. I'm not sure which speed I'm missing but if I had to guess it would be 2nd. Any ideas on how to proceed with investigating the missing gear issue. If I remove the lever that controls the gear plunger will it pop out?

Also, below is a pic of a loose bolt on the left side of the pic (right side of D31) below the valve body. I can't see that it holds anything but to tighten it I had to remove the lock washer. I might try a slightly longer bolt but I'm curious if it will cause an interference problem inside the tranny.
