It runs strong and accelerates as is should. In the cool mornings it shifts as it should. Once it warms up (30 min drive or so) or hot...

It's soft and pliable, and it is made to withstand up to 390 degrees Fahrenheit, which is way more than what the...

    Disconnecting slave from clutch line?

    I need help getting this slave off this hydraulic line. As you can see it’s pissing fluid and my clutch won’t disengage. I got the cotter pin out but nothing different happens, it still feels like the clutch line is attached in another way.
