http://s839.photobucket.com/albums/zz311/BIGREDGOAT1/Broken%20Getrag%20pictures/there is the link. thats a few pictures i havent got it completly apart yet. i just took a few pictures of it to show everyone. i took one picture of the synchro assembly. it looks like some brass from the 2nd gear is gone. right where the assembly slides... but on 1st. its all there. or so it appears.

The input shaft is twisted. at 313hp and 782tq. that isnt healthy

 

wow i thought these could hold more than the numbers you are running. how many miles are on that tranny and what were you pulling?

 

ya Derrik I would probably change that assembly I can see a lot of heat in that whole cluster when it changes colors it changes the whole structure of the material

 

d@mn it brice, that isnt what i wanted to hear. did you notice the brass though?

and as far as i know, 186,000 miles and it was still running when i pulled it out cuz my 2nd gear wasnt functioning correctly

 

ya see what you can clean out ant we will go from there and for the love of god man dont take this apart like you did on the back there a ***** to put back together

 

hey guys im new to dodge trucks but ive always wanted a first gen cummins and i finally got one. the only thing i dont like about it is the auto trans, if i was to switch to a manual what would be the best to go to?

 

use the search button in the 1st gen section there are some good reads about that question

 

Number 1, what's shown in Post #5 is NOT the cluster, it's the mainshaft, synchronizer assemblies, and it's gears.
The cluster is what is erroneously referred to by some as the the "counter shaft".
The counter shaft is the large "pin" that holds the cluster gear into the case.

Number 2, that heat damage didn't come from pulling alone, that was from long term continual low lubrication at road speeds, "neglect", if you will.
Resting your hand on the shifter while driving down the road can also do this, as well as burn up the shift forks in the top cover.

Given that the transmission is in great physical condition and doesn't have issues, the Getrag will hold the numbers this gentleman has, but you gotta' keep them overfull so the lube gets where it's needed.
You can't run gear lube in them and expect them to last, either, they weren't designed for that type of lube.

The NV4500 also has it's own set of issues, from a power standpoint, mainly mainshaft and 5th gear retention related, plus lube requirements.

Either is a "Light Duty" diesel transmission, which is expected to take people turning them up 200+ horsepower above their original design limits, which they weren't intended to do.

Mark.

 

Lol yes, I got the truck about 30,000 miles ago and am guessin that the heat damage was already there

---AutoMerged DoublePost---

when i got it, i over filled it. so i didnt create the heat damage.

 

LOL, I didn't say you did it, just the likely causes of why it happened.
Most of us these days know what the consequences of neglecting these trannies can result in.

I've seen perfectly good, well maintained NV4500s with all the best pieces, puke their guts for no apparent good reason.

Sometimes it's just the luck of the draw.
