Cat 315AL stuck in high speed tracking

[Tim98TA]

Serial #6YM02363
Light switches on monitor if I move it to low speed but the machine does not respond.
Being in high speed the machine will not turn on its own.
Could it be the low speed solenoid/valve not reacting? I'm not sure of the process when the button is pushed.

I think you will probably need two things. The System Operation document for the hydraulic system that explains how the 2-speed travel works, and the electrical schematic to go tracing power. I need to go digging for the first one, I'll send you the second so keep an eye on your messages.

Attached the SysOp document for the hydraulic system.

I have bad swivel seals do similar but soon or later it would find low for a little way.
Something to check

Thank you Nige. Much appreciated.
Tyler, we recently rebuilt the swivel. It was doing it before then as well.
