Honda 420 Rancher 2005 shifting problems

[sunvalleyfarms]

I have a 420 Rancher I deeded to chage out the battery after doing so, It will not shift gears in forward and in reverse it runs like the engine is flooded It was fine before I change out the battery.?

this is the 420 with automatic transmission This happens if in auto or manual I have run out things to check.

Have you read the service manual ? Is the dash flashing ? Have you tried getting the trouble codes out of the dash ?

Are you sure the new battery is good, and fully charged ? Have you checked the charging is charging, and regulating ? Are you sure you didn't momentarily connect the battery up backwards, or try to jump start it but connect the jumpers backwards momentarily ?

When you say it won't shift gears in forwards, do you mean it moves but only in one gear, or that it won't go into any forwards gears ? Just to clarify before I start looking in the books.

And in reverse, it moves ? but the engine runs badly or just has no power ? If the motor is running ok, but has no power in reverse it might be a gearbox/control problem, or it might be an engine problem..

Bummer when someone posts a question and members take the time to reply and the OP never shows up again.
Thanks @Mech for posting so much on the forums and helping others out. I am new here but looking forward to peruse the forums here and there and learn how to better service my own ATV from other people's problems and solutions and perhaps with time and more experience contribute back.
