TRX 420 AT TRANSMISSION ISSUES

[ericggg]

Hi, all 

I have a 2010 Honda try 420 at and I'm having an issue with the transmission.  Every now and then the while riding the transmission goes into neutral or stays in gear high or low.  Recently while riding it stayed in 4th gear, had to come to a stop and rock it back and forth and it want back to first.  Did any one have similar issues and what can be the diagnosis to this problem and is it worth fixing.  I called the Honda atv dealer and told them what happened and they said it's going to be $2000-$3000 to fix that seems crazy.  Any help or idea will be greatly appreciated.  

Thank you all

I presume you mean a TRX.. 

You really need to get a service manual and have a read through the diagnostic section about the trans...

I'll get a book and have a read but it's going to be pretty impossible for me to talk you all the way through if you haven't familiarized yourself with the bikes layout and what's involved, and not much point if you don't feel up to doing the checks..

This would be called a rancher would it ? And the trans is called hondamatic ? Sound familiar ?  There are several variations of what can be described as auto.. some are just auto shifting manual boxes.

 

Oh I see the AT..  I got the model..

First question is.. is the dash flashing it's gear position indicator ?

[ericggg]

yes, the gear indicator on the dash was flashing when it popped out of gear.

Yup well it flashes a code, a two digit code. Count the flashes and let me know what it is and I'll look in the book.. But you really need to look at the manual so you can follow what I'm describing.

The code is probably made up of long and short flashes. Longs are tens and the shorts and ones. So long short is 11 long long short is 21.. I think that's how it will be.

ok, I'll try to figure out the code this weekend thank you for your hel
