Np435 transmission help
I’m currently rebuilding my np435 transmission for my 1980 ford f-350. I’m almost done but when I measure the clearance between the 3rds speed and syncronizer it’s like way out of spec(.12 when spec is .070-.095) i want to add shims but can’t find any anywhere is there anything else I can do or anywhere I can find shims in stock?

Who did you get the rebuild kit from and I am guessing you checked with them?
Who else have you checked with and is it they done have in stock but can get them or are they N/A as there is a difference between the 2.
Also if they dont list the shims in their sites I would give a call just to make sure they dont have them and ask where you might get some from.

It must be something with the NP435 as my 3rd / 4th shift is not happy but I bought the transmission used so who knows what it had been thru?
Now I have a BW T18 that this NP435 replaced that is really bad as it has chipped gears and no syncros and why it was replaced.
It is also how I bough the truck.

Synchronizers are a normal wear item like the bearings and should be replaced if you have the tranny torn down.
