Hello, in my vehicle (2004 1.4 HDI Manual 260.xxx km) there is a loud rattling noise coming from the transmission when idling. When I press the clutch, there is a quiet engine sound, when I release the clutch, it sounds like an as250 dodge sound (pressure - lining clutch bearing was changed 1 month ago) also there is a humming noise in the gears. It makes a distinct noise in 1st, 2nd and 3rd (when I take my foot off the gas, a whining sound like on buses) Also there is a slight whining between 2000 rpm and 2200 rpm in 5th gear By the way, it has been 20,000 km since I changed the oil of my transmission. I had German-made oil put in, my mechanic recommended it, I did not skip the oil and I checked the oil, there is oil, I asked the mechanic about this problem. He told me that the plug pole is broken and the 5th gear will be changed, he said the transmission needs to be disassembled. He said it was a sealed box, but you never know what you'll find inside, so I can't give you a price. The other day, I came across a solid transmission from a 110,000 km 1.4 HDI 207 for 4,000 TL. I asked him about it, and it was the same transmission as ours. Should I just buy it and have it installed (1,000 TL labor + 500 TL transmission fluid) or should I open the transmission and start repairing it because the noise, especially at idle, scares me. I don't want to handle the transmission, as I'm a long-distance driver.

The input shaft is directly connected to the clutch disc and is the part that moves the transmission. When you depress the clutch, the flywheel and pressure plate continue to turn with the power it receives from the engine. The clutch disc, located in the clutch disc hub, stops because it is disengaged from the clutch disc. In other words, the transmission stops because it is not drawing heat from the engine. Naturally, there is no noise from non-rotating bearings and gears. Contrary to popular belief, even when the vehicle is idling, some of the gears and bearings inside the transmission are spinning because the input shaft is rotating. During this time, the bearings in the input shaft, which most manual transmissions have two, can become worn. If these bearings are pitted or faulty, the noise produced by these bearings at idle can be loud or quiet, depending on the degree of wear. This is what is said to be coming from the input shaft. In short, the noise you hear at idle stops when you depress the clutch disc because the transmission stops. The humming problem in the gears is that each gear has its own gear. Which gears are responsible for the humming noise? The gear shifts. The noise you hear when you release the gas pedal comes from the bevel gear bearings, which are the differential part of the transmission. However, once the transmission is opened, everything becomes clear in the hands of a good technician. The associated costs are also evident. Nowadays, mechanics don't repair transmissions like they used to. They disassemble the transmission and send it to a transmission repair shop. The technician repairs it, and the technician reattaches it to the vehicle. Therefore, even if you send your transmission for repair, the technician will send it to a transmission repair shop. If your transmission is in a condition that can't be repaired, the technician will indirectly direct you to a used transmission. That's the way things are in the market; the rest is up to you. I hope I've explained it well. Good luck.

Yes sir, for such reasons, is it reasonable to buy a replacement and change the transmission in advance in order not to pay for the opening of the transmission? The transmission will be under warranty.

If the used transmission is clean and under warranty, it makes sense to keep the transmission you removed from your vehicle as a spare for a while, then sell it or keep it as a spare part, depending on the situation. 1e1b2023-05-05 22:55:18

[QUOTE=SonerUzn]Yes sir, does it make sense to buy a used transmission and replace it in advance to avoid paying for a transmission repair shop? The transmission will be under warranty. [/QUOTE] I actually explained the process. If the people who disassembled the transmission and bought the new transmission are the same, maybe there will be no problem. But for example, the transmission repair shop gives a warranty for the transmission. Yes, they will give you the used transmission and will definitely buy the transmission from your car. They will also take the fee you gave as an example. A different person, the mechanic, will charge you a separate fee for the disassembly and assembly of the transmission. Maybe there is a small fault in the guaranteed transmission. Then the person you bought the transmission from will take back the faulty transmission because it is under warranty. Everything up to this point is normal, but what is not normal is that the mechanic will disassemble the transmission again and assemble the new one. For this, they will require another disassembly and assembly labor. You need to agree on this issue from the beginning with everyone who will do this work, sell, disassemble and assemble, so that no one will be upset in case of any problems. In short, the goal is to fix the problem in your vehicle as quickly and cheaply as possible. is to be solved. Berkay Erdinç2023-05-05 23:32:42
