Getrag 360 jumps out of 1st.

[GoatBoy4570]

Hello...
Kind of an obscure question to put forward it seems as i haven't even found a hint on a internet search.
So i'm looking at a 1993 Dodge D350 with mini dump firewood truck that's seen some hard bush work.
The relatively low mi. 5.9 runs like a champ but the transmission on the other hand is another story.

The problem,,,, the trans kicks out 1st gear as soon as the clutch is let up. Even on the flat with no load its spits out 1st as soon as the clutch starts to engage.
I realize this trans is gonna need a full overhaul kit, perhaps including the needle bearings too. what im concerned about is 1st gear itself, is this gear going to have damaged teeth where the shift collar engages the gear? im thinking probably so i should replace that too, but where to source that gear? it looks like i can buy a 5th and a 3rd but i didn't see a first gear.

im wondering what would have caused this to start with? perhaps being stuck in the mud and lead footing between forward and reverse in a effort to get moving.

Anybody got insight on this problem ?
Maybe i can buy a good used gear from a rebuilder somewhere, or even here?

Thanks and looking forward to meeting some folks here.

These guys appear to have a good selection of parts for the Getrag, including rebuilt units.

Its a combo of bearings andf syncros . Nobody has had much luck rebuilding .Id source a nv4500

I was hoping a ''been there done that'' would respond or even a ''so and so had that problem and he did this''. Blowing first is some kinda rarity, probably not gonna get to much insight before i rip into this one.

I guess replaced minebfor the nv450

Was the NV4500 a rebuild or used, was the transmission a easy find?

How much did that swap cost?

I got a NV4500 from a dodge gas truck for $500 then got $900 worth of parts from Standard Gear and Trans to fully rebuild it to diesel specs and fix the the 5th gear issue the 4500 is known for, when I say fully rebuild i mean every thing, input shaft, main shaft, 5th gear and retainer, cluster gear, plus all the bearings and syncros

I bought my NV4500 new from a guy whom bought it and sold the truck for $1200 there is a in Bend Ore on Craigslist that is a rebuilder good guy to deal with
