I have a 200es big red. it was chattering in 4th gear for a while. and now none of the gears work it even chatters in neutral.

before I rip the engine open is there any thing I should check ?

it seems wierd that it makes noise even in neutral .


also would a 200s transmission fit in there ? I have 2 spare trannys from a 200s . but I'm not sure if there the same maby someone on this board would know comatability.

thanks in advance. I would like to save this atc from the junk pile .
