Recently, my unit Axis 500 (2020) will only go into reverse and neutral. I am not able to get high or low. The engine itself sounds fine and I do not have other issues on this unit. I change the engine oil but have not yet changed the gear oil. Before this happened I occasionally encountered issue where going from reverse to high gear, it would grind some and i had to reposition to shift into high gear. I also for last couple weeks heard a squeaking sound. I couldn't tell what it was. Was looking for a grease point I missed. The unit has around 70 hours and is kept in the garage. Anyone else encounter this type of scenario? Any suggestions on troubleshooting would be appreciated. Thanks. -

I've seen those advertise on the net. Seen a guy on YT that installed one. He said they work. But like you, I would like to hear from others before I installed. They are kinda expensive. There's a writeup here on how to get into the ECU to read codes and get the engine parameters (parts and software required). From my understanding the ECU also has flash memory that some parameters can be changed and saved. I haven't tried it. If you do let us all know how it goes. Good luck. -
Boydog40, Don,t get in a rush and don't hook color to color just yet. I will find the schematic and try to help you get it wired. I'll get back to you. -

Just because your machine is a coleman it is made by Hisun. Just like the Massimo, (my) Axis, and others. The computer reset is the same. Hisun uses the delphi MT05 ECU. There is 2 ways. I like option 2. And should always wait for fuel pump to build up pressure and kick off before attempting to start engine Option 1 (From MotorCycleDoctor . Com) . Start machine. Leave it in park. Warm engine for at least 2 minuits. Hold throttle wide open for 5 seconds. The rev limiter will prevent it from blowing up the engine. Turn off engine for at least 15 seconds. Then start machine and allow the computer to re-learn the computer. Option 2. Start with the machine off. Turn keyswitch to on. Make sure the fuel pumps kicks on. Then turn the key back off. Do the on off thing 5 times within 30 seconds. Make sure the fuel pump kicks on each time. Once the 5th time off, leave off 30 seconds. Then start and allow computer to re-learn. ECU-Reset-5.pdf -
Jim, Keep good notes because I believe I'm heading that way myself. Lot's of pictures.
