Hey can anyone recommend a good trustworthy tranny shop ..im drivin a 85 bronco with a 300 inline 6 it has a np435 4 speed in it. its throwin itself out of third gear under load mostly ..think its the syncro.. not set up to do it my self.. so easy to get burned out there.want to make sure its a full rebuild not just the broken syncro that gets done...:confused:

do you have a bodylift? make sure the body isn't hittin the shifter. could be a detent spring, not sure how they work on the np's. likely is a sliding collar though...

It's usualy bad bearings that'll make a syncro pop out of place. Happens when helical gears go out of alignment under load.
