Ok, so I just changed the transmission (and center diff. since it shares the fluid with tarnny) fluid on my 2005 WRX STi this weekend (car has 55k miles and I am second owner) and now I have steering wheel shudder at very slow speeds when turning the wheel.
I can feel the shudder transferring into the steering wheel as you turn the wheel just off center, but most noticably at very slow speeds. I swear I don't remember this happening before changing the fluid, could I have intoruced a problem during this mundane fluid change?
I extra-S (4.1 qts) from Fred Beans and followed the instructions on the on-line manual http://ken-gilbert.com/wrx/STi_Manual/
Any ideas? Could I have introduced too much or not enough air into the system to cause this? Any help is GREATLY appreciated!
