Been having intermittent hard to shift into gear usually first and fifth. Sometimes at a red-light but other times when I'm already moving. If I try to hard it starts grinding.. The other day I kind of "gunned" it in fourth and could not at all get it into fifth. The fluid looks dirty - If I wanted to change all the fluid would I just follow the procedure for bleeding until all the fluid comes out? I think I saw a procedure under the "pages" link. 91 TT aftermarket clutch that has been working fine for years problem has been in the last several months only..
