Hi
We are stillrunning a Valmet 6600with the serial nr. 664599. Now, the cicuit for the Delta Power shift gave up and the Part is not available any more. And, to make it worse its competly casted in epoxy.
Did anyone rebuild this circuit or has a scheme for it?
This should be very low tech
On my 1998 Valtra 8150 (mega) there are only two on/off selenoids, and some hydraulic schift valve.
So both off is direct speed (1)
One on is second speed
The other one on is third speed
Some olders may have the direct drive in the middle speed.
So you could build something with just swiches and double pole relays.
Are you sure its dead, there are a switch (s24) on the clutch pedal, that disconnects the delta power shift, to make shifting gears easier, just to be sure.
I disconnected it on our 6800, 10 years ago

You can install the newer control unit in autocontrol 2 tractors. Se attached instructions.
Thanks a lot for your help, i really appreciate it.
@ roblui that would be perfect. but i can’t get the mounting kit 33464200.
So if someone has one for sale let me know.
@ Pat that would be my plan C if everything else fails.
@ jlbjerre a wellknown switch shortcut when i boght it but impossible to shift. so i reinstald it
