First off let me say. I just had my transmission fluid change this summer. On my trip to Lewiston ID I had the Quadzilla on Level 2. I made it to the Casino outside of town and stop for a minute to grab a few things. Pulled back out on the highway rowed up through gear and it started clicking. WHAT?! Any gear had a very loud clicking noise even neutral as long as it rolling. I figure out pretty quick its was the input gear from the input shaft. Towed it home and pull the transmission. Yup you can twist the input and feel the gear is got broken teeth. 

 

NOTE: Remember the Quadzilla was on level 2 (stock fuel), fluid was just changed this summer and fresh and full. When I drained the fluid is was still clean but full of fine glitter.

 

Now I opted for a different trans builder. I got a connection with a builder up near @Dynamic up there in Northeast Washington. The gents name is Jason Hammer. He dove in and looked over my transmission basically I wore the hard facing off the those gears with over 435k miles. Totally normal wear for those gear and distance since those gears never been changed. Now the countershaft is one unit and will be replaced as a full unit. I'll post up the carnage as soon as I go back up north 5 hours away to get my transmission.

I don't even like the 6 speed in Thor. Row 4 gears just to get to 25 MPH. Just 2 gears to get to 25 MPH in The Beast. 

 

Now to give some more to the site then gent (Jason Hammer) doing my rebuild is going to teach work to rebuild Nv4500 and 5600 the the g56 as well. Then he's will to register up and help others with manuals. Funny part really close to @Dynamic. East side of Washington as well.

I was wondering why you aren't doing the build builds rebuild yourself.

 

Ive been wondering where dynamic is and if hes doing all stuff in house or still sending stuff across the world. 

No experience or tools to do the rebuild.

 

Dynamic is still doing in house.

 

Yeah sorry about my last post too many things going on and need a break.

 

Jason Hammer is my guy doing my rebuild. My transmission broke the input gear and the countershaft gear. New countershaft and input gear and being installed. So Jason said he'd be willing to teach me how to rebuild all manuals for Dodge. Then was will join the website and help other members too. Sad part I just found out he's COVID positive and he's trying to finish my transmission for me. As for Jason he's close to Dynamic.

I finally return from up north getting my transmission back. Yup I wore out the gears for the input and counter shaft. Look closely the input shaft had worn through the hard facing and then weaken the teeth and broke off. Again when this failure occurred I had the Quadzilla on level 2. Remember all these gears now had 435k miles and just plain wore out. Jason told me my previous rebuilder (Weller Truck, Boise)did a good job of rebuilding last time and he seen all the updated stuff in the transmission. There isn't much left to upgrade...

 

As for Jason Hammer I talked to him and he's more than wiling to join the forum and help other manual transmission owners. He's very knowledgeable and can work on ANY manual transmission. He is self taught as well. Now here in the future I'm planning on going back up to Spokane, WA and learning from him. He gave me a stellar price on the rebuild and 1 year warranty from this point on. Next step to re-install the transmission.

 

Input shaft and damage...

Here you can see the wear that weakened the gear teeth after the hard facing was lost.

As for the NV4500 transmission the counter shaft is one piece. Nothing to do but change the entire shaft.

Then the gear itself...

Purdy.

 

Yeah were gona break 500 on the 07 by Christmas. It hasn't had any transmission work. Just a few clutches maybe at its low power and lowering level the transmission will outlast the truck.

 

I have been impressed with the reliability of my 47re after throwing parts at it 8 or so years ago. 

Not sure if its cost to build versus some manual trans parts is better not. 

Just in clutches the 07 is nearing what i spent on the 47
