This is interesting, because as we mentioned at the beginning we did not replace the bushings in the countershaft or mainshaft, and by this time they had 134,000 miles of wear.Īfter obtaining all this data, I sat down for hours analyzing it. In this case it was equal to main line pressure, proving no pressure lost in circuit 30, which leads to the third-clutch pack. I looked for any pressure lost in the third-clutch circuit while the transmission was hot, and as Figure 3 shows, third-gear oil pressure was within the 10-psi difference allowed between application pressure and main line pressure. I even monitored the duty cycles of linear solenoids A and B during upshifts and downshifts. I obtained main line-pressure readings along with the pressure reading for each application clutch, amperage reading at linear solenoids A and B, and voltage readings from each shift solenoid and the third and fourth pressure switches. I connected our test equipment to the vehicle ( Figure 2) to obtain as much data as possible. We also did not re-flash the PCM to the latest software or replace the pressure switches. We did not replace the bushings in the mainshaft or the countershaft, since at that time we did not have the tools to replace them. When we rebuilt the transmission three years ago, we installed an overhaul kit with Honda original clutches aftermarket rebuilt converter new linear solenoids A, B and C and new shift solenoids A, B, C and D. We did this to find the original cause of the failure. That is, we replaced the third clutches and steels with Honda original equipment, installed an aftermarket rebuilt converter and thoroughly cleaned the valve body. I wanted to put the transmission as close as possible to the condition in which it came in but in a workable state to obtain the readings we wanted, so we repaired the transmission only. So I bought the vehicle because I thought it would be perfect for finding the cause of the third-clutch failure, since we knew the vehicle’s history. I am not very knowledgeable technically with cars so your views are very welcome.The customer was not too happy with a vehicle that had experienced two transmission failures in 134K miles – the original one at 60K and now the rebuilt that lasted 70K. This is a big shock to me so I was wondering whether anybody else on this forum had similar experiences and whether I was missing something and whether I was being taken for a ride. They also claimed that it could cost anywhere from Rs 2,500 in the case of a) to over Rs 1,00,000 in the case of c). I didn't have any history of a transmission problem so I am completely confused and not sure whether there is indeed a problem. and they suddenly told me that my transmission was playing up and apparently for a few minutes they got no power at all from the accelerator and that based on the data from the DTC that they needed to keep it for another day and a half to see if:Ī) there was a problem with the transmission fluidī) there was a problem with some solenoid The Honda Service Station (Courtesy Honda in Okhla, Delhi) finished most of that and I went back in the evening to pick it up when they suddenly told me there was a problem with the transmission.Īpparently they were doing a final test ride to ensure the heating issue had been fixed etc. I took my 2004 Accord AT for a 50,000km servicing today and there were a couple of minor issues I had identified like the actuator for the front passenger door lock and the engine overheating at times etc. I am new to this forum and wanted your advice on something that happened today.
