I'm puzzled

Kinda sounds like one of the 3rd gears snapped a cross pin / hogged out a spline holding it to either top or bottom shaft.

Pull the trans case off, run it upside down in 3rd and squeeze tires on an axle to put load on it. Should be able to see which gear slips on shaft.

either that or the shiftier is not throwing the gear far enough to engage, see if you can get it in manually

>that's what she said!<

Thanks for coming through, on manual shifts ok, I changed the servo to a metal high torque, much better but not perfect. Just like real car, switching into third from stop, takes a lot of throttle before it takes off. Not The same as my other High lifts, but at least it moves.

check out the servo throw, it might not be engaging enough, longer servo arm or adjust end points on radio if yours has that setting
