Np 435
I have a NP 435. The only problem I am having is that it will 'walk' out of first gear after awhile. It does not 'pop' out but slowly 'walk'.
I would like to know what causes that to happen. I have it out and the cover off but can not find anything so far. The inside looks good.
Can this be a problem in the shift tower? a rail? or dentent spring or ball?

A few years ago I replaced one in a 86 F150 for a friend. We found a nice one in a bone yard because we found that the shift rail parts were expensive and had to be ordered and it was cheaper to get a used one than try to rebuild old one. There are two verisons of 435 used in Ford trucks that year. The 2wd and 4wd models have different output on them so be advised if you look for one in a bone yard or buy a rebuilt one that there is a difference.

Ford used the 2WD transmission on some 4WD with the "divorced" or seperate transfer case, so just getting one off a 4WD doesn't mean you get a 4WD trannie...
