Had some mechanic do it. I was right there with him when he did the mod. What a diffrence!!! Now from 2nd to 3rd at high rpms car shifts smooth. I think all manuels should have it done. Thanks Matt.

It took me no more than 2 hours to completely do that mod.

It took him about an hour. You can reach the Brass copper part of the masrer cylinder from underneith the car. If you can get the car high enough? But he took off the mastercylinder drilled through the small hole just over an inch cleaned it and had to blead the system again. Over all shifts better, and now at high rpms. Just costed me $40.00 to have him do it. Worth it to me.
