About to Change CVT Fluid
 

I'm about to change the CVT fluid in my 2002 Audi A4 1.8T. I have 79,000 miles and the maintenance manual says I need to do this at 40,000 and 80,000. Further, I'm getting some pretty severe juddering as if the tranny is slipping under certain conditions. From what I've read, this is a sign that the fluid needs to be changed or the clutch needs to be upgraded to the new 7-plate version. Either way, changing the fluid is the first step from what I've read.

Is there anything I need to know about this procedure? I have the repair manual, and the procedure requires two special tools -- the VAS-5162 tank that you hang on the hood and use to re-fill the tranny, and the 3357 tool for opening the fill plug. Do I really need these tools? Any suggestion on where to purchase them?

Also, it says the car needs to be level -- does that mean the bottom of the transmission, or the car?

I'm having trouble finding the VAS-5162 tank. Does anyone know where I can get one?

the tools are the same for bleeding the breaks

Oh, cool. I need to change my brake fluid at some point too. According to the manual I'm supposed to do that about every two years.

So how do I use this to do it? Does it come with an adapter that screws into the filler plug on the bottom of the transmission? The device you were referring to is the "Eezibleed Brake & Clutch Bleeder Kit," right?

Oh, I see. I can't find the filler bottle, though -- that's what I'm looking for.

Hi:

I'm going to do it, too. Would you tell me where did you buy th CVT fluid? it is from dealer?

Thanks

I'm trying to track that down too, I'll let you know when I find it.

the CVT fluid should come in a 1ltr container which has a long tube in the cap but some don't so you need a container to pump the fluid in ( ATF fluid containers generally have this feature ) and worth hanging onto an used container,

only other way to get it in there is via a long tube with a funnel on it then put the tube into the filler on the tranny and fill till it overflows then its done put the bolt back in and off you go,

the break bleeding system come with directions and its a one man kit you want

I guess it'll make more sense as I do it, it just seems weird that I'm filling the tranny from the bottom... seems upside down. :-)

You forgot to add that the tranny fluid temp needs to be between 35 and 45`C to be at the correct level when it starts dripping out

RE: About to Change CVT Fluid
 

Yeah, I knew that from the manual at least. I'm looking everywhere for the fluid though, I can't find it online. I'm still looking, I'll post a link to it if I find it anywhere....

Dealer should have some

RE: About to Change CVT Fluid
 

Yea, gonna call them tomorrow

RE: About to Change CVT Fluid
 

$15/liter from the dealer. not bad. I'll pick some up Thursday.

silly i know but the temp is when the engine is running for fluid level checking with engine temp at normal, auto tranny fluid expands under heat where as oil just gets more malleable when the viscosity is right depending on the engine;)

Okay one last thing -- according to the manual the tranny holds 9.0L of fluid, but when you change it you only need 2.7L. That doesn't seem very effective.
