What do you mean? This is custom made.

Hello! If you are 100% sure for the hydraulic pumps, the only other connection to the hydraulic system is the emergency parking brake relief valve. I cannot find any other place that the two oils could be mixed...

Hello! Sorery for the late reply, just saw this comment. Yes, we do test Ecolife with our device.

​@@christosmourafetis1656Can I know the brand and price of this device?

Hello!! What exactly do you need? Can you send in English please?

In all gears? What is the model of the transmission?

Not in our setup. We use our own device to control it. 😉

What do you mean? I cannot understand unfortunately...

With a hydraulic motor driven by a 300hp engine.

Hello!! No, there is no provision for temperature sensor on the AT. On the side we have neutral start valve. If you want to istall a temperature sensor, Allison puts in on the outlet from the transmission to oil cooler, so you have to find that hose, install a T of somekind and add a temperature sensor...

Totally different engineering schools. USA vs Germany. USA is more friendly to the Engineer, and have the trend to make things big and long lasting. ZF on the other hand has managed to transfer much power in such small volume. This makes things more delicate, and easier to brake. So, both have their advantages and disadvantages...

@@christosmourafetis1656 Ok thanks 👍 I work in a repairshop for Dana/Spicer. So we do alot of repairs on Dana Gears.

@Stefan Andersson where are you located?

@@christosmourafetis1656 In Sweden, little outside Stockholm.

@@stefanandersson7969 Great!! I was there last month!!!!!

Hello!! You refer to DANA 32000 transmission? What was the problem in the first place? If your pressures are OK, you either have a problem in the torque converter (most probable since your problem is in all gears, and both directions), or you have worn discs or some other mechanical failure. In general, if our hydraulic circuit is OK and the pressures are all ok, then the transmission has to be dismantled in order to identify the mechanical failure....

@@christosmourafetis1656 it was said to slip while driving then went on a stand still, it just shake when you put it in to drive. I I remove the prop shafts and engage a gear it starts slowly and gain speed and when you put it from front to reverse while in gear it slows down and stops then follow the direction of the gear Pressure on Pump 240-260 Spool 125 Toque convertor 120 psi

@@christosmourafetis1656 yes its a Dana spicer 32000

Is it with a remote torque converter?

@@research5136 Is it with a remote torque converter?

Yes, it is changing gears. The drive is hydraulic.

What kind of problem? Please send an email at cm@jpc.gr

I just wish the ecomat would adapt to driving conditions. When I’m doing 40km/h in a quiet neighbourhood and barely on the accelerator, I don’t need transmission in 3rd gear making the engine scream at 2000rpm 😅

@@AllieGee95 The Ecomats i know had a different issue... They changed to gear 6 at 40km/h :P litteraly straining the engine with too low rpm (750rpm) It's usually down to the loadsensor....

@@AllianceB95 OH they had Topodyn, but it was poorly programmed it seems. See I wish ours had Topodyn but with adequate programming/behaviour. We’ve got a similar issue with our Voith DIWA854.5. It shifts too early. Cummins ISL8.9 has a redline of 2300-2400 depending on the MY. The DIWA it’s 2500 rpm… the damn thing always shifts at 1600-1650 on gently accelerations and when flat out on a steep hill, it will only reach 1900. It’s frustrating cuz it still has 400-500 rpm left to give. But nope it’s like “nah, I wanna take it slow”. Acceleration is pathetically slow. Bus #1207 seems to the be slowest in the fleet. It’s a NovaBus LFS Artic with said ISL8.9 and DIWA… I timed it the other day… 1m38s 0-100 km/h 🥲 it was a pain. The 80-100 was the longest part at a whopping 55 seconds.

@@AllieGee95 Just the tought of that slowness makes my foot hurt because of all the thrashing i would do... Try this: If it does that 1900rpm shift again... Right when it does that let go of the trottle and smash the trottle... that might cause a panic attack of the voith doing a downshift and it might not change gear untill 2300rpm or higher. (it works on non kickdownbusses too)

All is fine here!! How about you?

Hello!! Please send me an email at cm@jpc.gr and I will send you the information you neeed. We will also need the serial number of the machine.

What do you mean? There are no electronics in this unit...

@@christosmourafetis1656 some models have it some dont

Well, they are strange but really cleverly designed transmissions...

@@christosmourafetis1656 fairly bulletproof too, you're right... But what a terrible noise they make 😬

Don't whine ಠ‿ಠ

The retarder is nice. I enjoy riding in busses with voith!

As an operator, I prefer the Voith DIWA 854.5 we have vs the ZF Ecomat or Allison B400R for its smoothness and retarder performance. Yeah sure the whine can be annoying to some, but overall it’s a really great unit.

Can you please send in English? I do not understand and the translation is not clear enough...

Deu crt?

The other tap for pressure is almost opposite of the one you see. If you have no power at any gear, I would first check the main pressure. If main pressure is ok, then I would take out the oil pan and check for debris.

Hello! The valve is adjusted at 11bar according to the manual, but this pressure can only be reached in high speed. In our test, at 800rpm input speed, this pressure was around 5,5 bar.

@@christosmourafetis1656 Thank you very much. There's also a question. How do these boxes regulate the axial gap? If it's not a secret))

@@user-db2nc5ze3p The axial gap in the between drums and shafts is 0,1 till 0,3mm if this is what you ask.

True that. Although when in a bus, sounds much different!

I believe there is no retarder testing here?

What do you mean?

​@@jpctransmissionserviceco4695 theres an attachment nozzles in input and output control blocks specially for 1 to 4 gear pressures.

Anyway its only necessary for a fully overhauled voith transmission...for minor repairs maybe it cn be considered

We use a hydraulic motor through the PTO..

JPC Transmission Service CO ohh!! I never saw something like that

Great idea. The PTO point is the same as the input yoke, the result Will be the same.

Sounds like a seal failure of the splitter low clutch but it is also used in 1st gear, so you should have low pressure on 1st gear too. First thing to do is to check individual pressures at the side of the control valve, especially the splitter low one to verify that the problem is there.

@@jpctransmissionserviceco4695 but for speed 4 it's normal. if the pressure at speed 3 should not be normal, speed 4 must also be the same

@@develonmania splitter low is used on 1st 3rd and 5th, this is why I proposed to check the individual pressure of this clutch.

@@jpctransmissionserviceco4695 Okay, thank you for the information. I will try to do it and if there are any questions I will contact again

What would classify as neglect ? I’m just trying to learn since I own this transmission.

@Gone The pump i think.
