Transmission problem no more! :)
I successfully put together a dozer and worked for a little over a week. Everything seems to be working well, after a while the pressure in the transmission should be measured.
You were right, the transmission can be removed, disassembled and reassembled all in one day if you know how to do it. Not as complicated as I expected.
If someone else is confused, like me (unlikely) the display of D6N gears then-
1.5- 1st gear, high rpm
2.- 2nd gear, low rpm
2.5- 2nd gear, high rpm
3.- 3rd gear, low rpm
3.5- 3rd gear, high rpm.

The question is, what is affected by the "pressure accumulator" above the transmission housing and what are the signs if it has lost pressure?

The purpose of the accumulator is to supply additional oil flow in the power train system in any case where the pump is supplying insufficient flow. To measure the nitrogen pre-charge pressure you will need a charging kit. See attached.
