Motelec MotorSport

Hi , i having some issues with my truck , If i fit manual 2 in a hill the truck go very slow or don't go , in manual 1 go perfect , If i turn on the truck and fit directly D the truck engaged the gear go only 2 second and fits neutral , if i throttle up the truck engaged the gear but hitting ... I saw also in hill 1 and 2 go well 3 also but when change at 80km/h to 4 gear the transmission goes erratic and hitting, if i have full throttle at 3 gear the truck speed good but a "sound" "click" sounds from engine/trans bay .

I set up the trans pressures up 15% with my sct livewire , but no changes...

Anybody with same issue ?
