John deere that nobody can fix!

[kgas]

Hello , I have a premium John Deere 6930 with AutoPowr gearbox , but a problem is arising , it is always starting from the traction gearbox , it has been mounted by specialists more than 3 times , the maximum time it took was 20 hours of work and the traction box is always breaking, the last time I went to assemble it, start the engine and immediately heard it breaking ....
We went to measure the transmission box pressure and it was at 40 bar which is a high value, while the technician said that the transmission box is broken because it has a passage that increases its pressure.
I would like to know your opinion on this situation!

The tractor's on-board computer gives me the following errors:

PLC 221 328016.31
and
EPC 3 524176.19

Welcome to the forum.
Not familiar with that issue. Is that a pretty common European model?
I'd check with some sites on your side of the pond.
Here's a link where they talked about issues similar to yours. I didn't read the whole thread but it may give you some ideas.

JD Autopower box. Good or bad?

Wife's nephew was asking me last night what I knew of the Autopower gear box. He's seen a 6420 for sale and wondering about it. I know that a friend of mine had one on a 6410 which gave a lot of trouble. Thought I'd ask on here.
