Foreman 450 es wont shift above 1st

Hi, Im new to the Honda foreman. I just bought this one ac couple days ago. I bought it with the shifter not working figuring I could figure it out and put some money into it and have a nice atv to have. Its a 2002 Honda foreman 450es selectable 4×4. Trx450fe2(I believe)

So here the problem. With the key on, engine off you can press the shift button and it (with no problem) will shift firmly into reverse neutral and 1st gear easily. If you continue to go shift to 2nd you can hear the motor actuating and trying to turn, but no firm "clunk" into 2nd gear and the guage display will still read 1st. The same thing applies with it running but if course you cant hear the shift motor over the atvs engine. So im pretty sure the motor isn’t the problem

I’ve noticed also that the lights will dim slightly when shifting but it seems to look normal and not an excessive draw. It will run around the yard in 1st gear and will not shift at all. Reverse neutral and 1st are all I’ve got.

Now I tried to use the manual backup shift lever and running or not it is hard to move the lever and will not go into either gears from neutral. I don’t know if this is normal or not. With the key on engine off and I try to use the manual lever when I put pressure on it the lever the neutral indicator (the N)will start flashing.

The atv has a new battery, a new shift motor, and a new shift position switch. I’ve also checked the fuses and the main power and ground wires. I’m assuming this is a mechanical problem but im not sure and I would like to get some input before I go tearing into the case…
