I forgot to mention that when i'm engaged on any gears other than the netral, I can't move forward and only backward. I don't know if it's possible but maybe the whole gear system is upside down.

i'm pretty sure it's not the brakes, it blocks completly and if I try pushing it forward, it's making a sound like two gears rubbing because they can't support the force a bit like if you put reverse while moving forward. I figured out how to move forward by rocking it back and forward so now it's in neutral i guess because i can move forward and backward. There is still something wierd: the others gears are when i downshift but it's supposed to be the opposite. Sorry for the wait, I wasn't able to send the message.

I succeeded to put it in neutral but i'm still not able to go to the 1's, 2's, .... 5's speed.

lIndeed, there is no reverse. I'm pretty sure it's not the brake that is playing up, the wheels are completely blocked when i try to move forward. Where is the over-run/sprag clutch and what is it's fonction?

where would this lever/cable be if there is one?

I can only move it backwards but I manager to put it in neutral. You’re right, there is no reverse, I checked in the user’s manual but how is it possible that it does not move forward but can move backwards?

Can somebody help me? I am actually working on my three wheeler and I don’t know what to do: I can’t shift gears. I think it’s in reverse (because I can’t move forward but I can move backwards) but I can’t shift to any other speeds not even the neutral.
