Building a New Process 435 Manual Transmission (True Spirit #35)

The New Process 435 was used for a lot of years by a lot of truck manufacturers. For the most part, they are the same (or nearly so) internally. In this second-part of the process, I'll re-assembly the transmission.

I was wondering when we would see a new vid. Always good to see a detailed video 🤜👍

[@tanis4457]

Excellent presentation

[@charizardsniper5064]

What type of oil do they take? Does it matter or?

[@YoshimoshiGarage]

80/90 synthetic unless you're in the arctic or maybe summer desert/jungle in which use I'd use 30W and 80/140 respectively

[@alexnelson8]

Yes it matters. 80w90 GL-4 gear oil, not GL-5. Hard to find in auto parts stores these days, but available online.

Great video; it was clear, concise, and very helpful. Note for anyone working on a 70s Dodge NP435 with tapered input bearing: There is a roller thrust bearing between the input shaft and main shaft. Also, if you have a 2wd or divorced transfer case unit, you will need seal P/N: 8160S, as none of the standard kits (even for dodge) come with one.

Is there anything you don't know about building mechanical things? Lol

[@damnimcooltom1]

Oh, no... Don't feed his ego!

Had a np445 professionally rebuilt now it shifts super hard between 1st and second, what would be the problem, they did replace a new synchro, ?

[@YoshimoshiGarage]

I would expect a new synchro to make it easier. I wonder if it's adjusted tight and has to break in?

[@FranciscoLopez-qe3sm]

Is this the same as the one in the 1966 d200 with granny gear?

[@YoshimoshiGarage]

Probably. The NP435 was used for a lot of years across a lot of vehicles, not just Dodge. If it's a NP435, the only possible difference would be that input bearing being a tapered roller instead of ball, but the rebuild process is the same.

[@kikojofraserrano]

Thank you. Very well presented and thorough in all details.

[@ToddAnderson-gn4hi]

Yes

[@mikespoelker8963]

I believe that opening on the side you described as an inspection port is actually where the optional PTO bolts up for an axillary hydraulic pump.

[@YoshimoshiGarage]

Yes, you definitely can find a PTO that bolts to them. Could be a pump, or just a shaft to drive really anything you want

[@joekelley1014]

Excellent presentation. You explained the procedure very well. Great easy to understand narration also. Working on one of these in a Fairmont railroad motorcar with a 2.3 L Ford (1979) engine. I have used Novak Conversions for parts, I make all my gaskets. Thanks very much!

[@YoshimoshiGarage]

Novak is a great resource

[@joekelley1014]

Right now this 435 is bound up for some reason, we'll review your video in great detail on the reassembly process to make sure we have everything assembled correctly!@@YoshimoshiGarage

[@NCmoose121]

What rebuild kit did you go with and is it a good one?

[@YoshimoshiGarage]

Really it's all about what bearings are in the kit. Most of the rest is gaskets, etc. I went with a kit from Cobra Transmission but made sure to order one with name brand bearings.

[@dickdangles3453]

Just curious where did you find the clearance specs of 50-70 thousandths. I have one I need to go through again and see if my specs are correct and if all NP435 have the same tolerance’s. Thanks!!!!

[@YoshimoshiGarage]

In my factory service manual for 1974 Dodge trucks
