Check the bushings in the trans to make sure they are all in the right spots and not slipping out. Take the case off the trans and run thru the gears with the motor on. Look for for anything not moving or sliding correctly. I will try to open one up and take a picture of what I am talking about to check. should be the 3rd sprocket from the rear of the trans that is your second gear I belive. Ill double check for you. Also double check the rod from the servo to the trans, make sure it is the right size and adjust if needed just 1mm off and it could give you an issue too.....
