Dear All,
I would be grateful if you can give me advice/suggestions on the following problem
I have a 2010 civic reborn with a mileage of 100k, the car has been regularly maintained from Honda with all the fluids changed on time. With its age my car has developed one very annoying little problem, it vibrates on light throttle between the speed of 20-40, the amount of vibration varies randomly. I had the car checked at Honda City Sales and they diagnosed it to be a fault with the transmission and recommended a transmission overhaul. I had the ATF changed 15,000 kms ago but I changed it again and the problem was solved for a few weeks.
After about 2 weeks, the same problem has re emerged, although the amount of vibration has decreased but it is still there and can be felt.
I discussed the problem with another Honda technician and also read the blogs of 8th gen civic. Apparently this problem is fairly common in this model and the problem occurs when solenoids are clogged and are not able to distribute the ATF evenly at low throttle.
According to the forum and the 2nd Honda technician the problem can be resolved by changing the transmission oil 3-4 times after short intervals which would effectively clean the transmission. Honda does not recommend a transmission flush so the frequent oil changes would effectively clean it.
To perform this procedure I need clarifications:
1) Which ATF should I use? I have heard that AMSOIL ATF is better but the problem is my car currently has Honda ATF in it and as I cannot flush the previous ATF, so in order to use AMSOIL I would effectively be mixing it with the Honda ATF in the transmission, will that be safe for my transmission?
2) I also read somewhere Honda has a transmission filter and changing ATF without the filter can be useless, therefore should I change the filter, as Honda terms it as a non replaceable part. If I should change the filter can anyone please recommend a workshop where it can be done and from where can the filter be bought?
3) The last but the most important, by doing ether or both of the above can be problem be solved?
I know it is very long query but I wanted to describe the situation as best as I could, I would be grateful for inputs in this matter.
