13 speed splitter problem

I have been told that we are not supposed to do that with the RTO, but RTLO is good for preselect. I might have been misinformed but the strange thing is that it happens just sometimes in 5th gear.
And I agree that if I'm not supposed to preselect when I go from 5H to 6L that might happen, but why does it make a bang when I go from 5L to 5H. I don't know how else to shift that except flicking the switch and releasing the pedal...

 

You are right, that is other way to do it without getting the bang but I don't think they designed it to shift that way...
I already paid shop to fix this problem by rebuilding it so it's under the warranty everything they have to do from now on... and they are willing to pull it out again but my concern is that if they didn't find the problem first time, they won't find it now either

And now that you said you have the same problem I feel a little better, every time I would try to explain someone that I have a problem and what it does they would look at me like I'm crazy and don't know how to drive... I grew up in trucks, driving them and fixing them all the time, I did everything from engine rebuild to brakes except for transmission, my friend broke his arm and almost got killed with transmission so I avoid that...

 

That's how I'm doing it, thank you for confirming that I'm doing it right.

 

He was doing it all by him self and he isn't a very careful guy, I'm not sure exactly how that happened but he was hurt bad and couldn't work at all for months...
