The gear box was installed and appears to be working

The gear box was installed and appears to be working. The only issue I had is that it arrived with gear oil in the plastic bag. I tightened the bolts and hope that leaking is not a future issue. The company seems to be very responsible and will handle that if it is an issue.

Hi Marie, thank you for your detailed feedback! We're glad to hear the gearbox is working well. We appreciate your understanding about the oil and are here if you need any assistance in the future. Thanks for choosing Flip Manufacturing!
