Well Hello There Fellow Technicians And Hivers!
This Might Be One For The Books!
I say this because this transmission got a really big failure, a common one but what is different about this one is that the client didn't absolutely destroy it once it got the failure!
Most people would continue to drive along trying to gain speed out of the vehicle even when they know they should in fact stop and turn of the vehicle!
Kudos to this guy!
At first when I started tearing down the build I thought this was going to be a totally lost case, especially when testing the vehicle, we can some what predict what is at fault by how the vehicle drives and more than often we expect to see a lot of gunk in the oil!
This one didn't even have gunk on the magnet at all!
A Rare Thing To See!
Damn I was wondering when I will see one of these again. This is one of those pickups that has the stop/start function, when the vehicle comes to a stop it turns off and when you accelerate again it starts up.
I like tearing up builds and seeing something new inside it, not new to see but I haven't seen it in so long that it actually feels new to me!
Now this one didn't actually work right because of a loss of pressure inside the transmission, highly unlikely that this is the problem, let's dig a little deeper!
Cracked open, now let's pull out the internals!
I might be giving you a surprise, you'd never expect to see how small the actual insides of this build are!
That's All There Is To It!
It feels a little mad doesn't it? I'd say it feels a little mad, I knew the first time I was tearing these apart my jaw somewhat dropped.
It didn't make sense how that big pickup could be moved by just that alone!
I mean it's more or less three of my hand sizes. How even!
The Most Common Problem On These!
The most common problems on these are that this sleeve moves... It also doesn't move a lot! Maybe a quarter of a millimeter and that quarter makes all the difference in the world inside this transmission!
What happens when that sleeve moves is, it cuts off the oil supply to the channels, maybe not 100% but it sure loses some pressure along the way, whether it's 5% or 2% it makes a difference and the longer you drive with a loss of oil pressure the more it would get buggered up, slowly overtime!
It's better to lose all of the oil pressure at once than to slowly lose it over time, slowly over time causes slow damage and wear inside!
The Last And Final Clutch Pack!
The last clutch stack on these are usually slightly burned!
I wonder what I might see with this one?
Now this guy was really concerned, must have been because even the clutch stack that takes the first hits are in an almost pristine condition!
This guy can be so lucky he made the decision to stop and not drive further!
Now all I can do is spread it out and wait for bossman to give the confirmation of finishing up this job, it might be put one side for a few weeks till the client gives the go ahead!
