Re: Standard three speed trasmission stuck in first gear

sometimes the way the grears on the sm 465 mesh make them hard to shift and if it is a np205 they have to be rolling to get out of 4low. i have had one for 6 years now and it has done this a few times and i found if you rock the truck alittle it pops out fine. i think it is the syncrows not lineing up right. these will not do it in low do to the cut of the teeth.
