You said you changed the fluid, what fluid did you put in and how much? Also doesn't sound like you have driven it much if any in between all the work so I would start to ask why it started to sound like it does.

My first thought (didn't listen to any of the videos)....drain the fluid, look at the fluid, put in the correct amount & type and see if it still exists. There are good videos on how to do this, look for Help Me DIY on youtube.

Yes, but that particular transmission is specific to the 986 model. Unlike the 5 speed and the later 987 6 speed, which are more widely used in German autos.

With that said, stl is right about the fluid. One of the nifty little points about these trannys (5 and 6 speed) is that they are hypoid gear setups with a lot of brass. A lot of EP additives will chew that **************** up, which is why most people use only the oem lube.
