My Cat excavator 302.5C...

My Cat excavator 302.5C is sporadic if it will shift into high range travel mode. Where should I look to solve problem?

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Construction Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts.

My Cat excavator 302.5C is sporadic about shifting into high travel speed. Where should I look?

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

Fixing myself hydraulic oil full, sprayed speed switch on grader up and down control lever with contact cleaner

Mechanic's Assistant: Anything else you want the construction mechanic to know before I connect you?

When I drive it, about half the time it will shift into high range after driving for 5 to 10 minutes

Hi my name is***** will be glad to help. Test with an OHM meter the switch and wiring harness for continuity and open circuits. Inspect for damaged wiring and connector pins. If okay check the hydraulic filter for signs of fine metal or debris that would flag a component failure occurring. Let me know the results and if we need to dig deeper into this.
