HELP: A4 Transmission Problem?

I own 1999 Audi A4 2.6ltr which is having a weird problem. when the speedometer passes between 40 and 60km/hr, i feel a vibration on the whole body of the car. But when it passes 60km/hr (also before it reaches 40km/hr), the vibration is gone. Until now the assumption of the problem is pointed at the transmission (that is according to the audi dealer). Is it a problem if i use the other ATF oil instead of from the Audi itself? i am using Dexron III Mobil 1. the dealer said i should use the original Audi ATF oil to solve the problem. Any more ideas what kinda problem i have with my A4 and how to resolve it? thanks in advance.

You should be using the Audi fluid in your trans!!!!!!!! I have heard of center drive shaft issues on Quattro models, causing strange vibrations!!!!!! Question have you had your wheels balanced ? Remember Audi fluid in the trans!!!!!!! Your friendly audi tech.

...and its a 2.8, not a 2.6 ;)

wow..that's what i heard fr the audi tech in here as well.. i will change the trans oil with the orig then..however about the problem, it occured the day when i have the bonded rubber mounting for the transmission & tie rod been replaced at the dealer. Might it be coz of the problem as well??

My audi is 2.6 ltr not the quattro (12Valve ABC engine) . It's the asian version :p

i havent had my wheel balenced. FYI 2, one of the front shock is having oil leak as well but not yet a severe one

My audi is 2.6 ltr not the quattro (12Valve ABC engine) . It's the asian version :p



ooohh...ok ;) I didnt realize where you were from ;)

I have just balanced my wheels and i found out that both front wheels are bad. I swap those fronts with rears then , hence the vibration is still there but better. I am gonna swap four of them with others tommorow at the dealer..see if that the coz of the vibration. If not then my trans is broken or something :( gonna fill it with the original audi fluid though
