Take it out of automatic mine does the same thing if it's in automatic an it only has 3 gears on them an that's it no more an no lessI've owned a 2003 Rincon 650 for over a year and have been reading this forum from day one! I can almost always find answers here. I started with a Rincon that was smoking when I bought it and the prior owner told me it wouldn't go into 4th gear!:laugh: So I found that it needed top end service and that the wrist pin had severe wear. So a new crank/rod and top end service later I have it all back together and it runs like new... In first gear! When I shift from 1st to 2nd it feels like it's down shifting or almost locks up the back wheels... Nothing grinds or makes any noise it's just like the break is applied. I pulled the codes and have 10 (tcm) and 11 (tps) But I thought that could have been triggered by the disassembly process so I cleared them and they haven't came back. the service manual list a trouble shooting procedure for this that points to the 1st clutch... But it shifted great before the rebuild. Any suggestions on where to start would be great!
