Np435 help

[nabes68]

Ok I got it installed it works great I drove it for the first time 15 miles and gear oil looks to be coming out of a bolt hole on the drivers side. Looks like a mount of some sort what could it be any thoughts?

I had the same issue with my NP43, and the solution was simple...I over filled my transmission. If you don't have a crack in your case, or a pipe plug not torqued properly I had oil coming out of the rear 4 adapter bolts. Once the oil leaked to the proper level I had no more issues.

I will take a picture of it when I get home and email it to you.

If it help mine was a one ton it had a 35 spline output and the 7 1/2 inch input with 10 splines. Not sure if they have a different case or not

Must be a different case as I've never seen any NP435 that has any bolt holes on the drivers side. Of course I havent seen many of the larger truck NP's so it could be a mount for something. If a bolt fits I'd just install one.

This is the pic nabes68 sent, drivers side of the tranny. My np435 doesn't have the bolt holes either, so I'm unsure as well.

Sorry but as I remember there is a bolt that can be left out that is the leak.. Search about 2 years back.. That was when we all installed NP435's now everyone installs NV3550 ....... Maybe some other old fart will chime in.. But I'm thinking there is a bolt that needs to be added.

 

[nabes68]

Ok thanks will do that tomorrow does the length of the bolt matter?

 

[broncnaz]

shouldnt matter much that boss is pretty high up should be clear of any gears. just so its long enough to thread in the hole to stop the leak.
Both the NP435's I have are slick on that side. pass side has some bosses but not the drivers side.

 

[nabes68]

Thanks that's ht I thought about the length of the bolt but wanted to make sure. And yes I think I have a oddball np435 it's the same size it just has those extra bosses on the drivers side

Put a bolt in and the leaking stopped took it for a drive and it didn't mark it's spot. Or it's out of gear oil
