hey jakey boy I'm pretty new to this forum but I'm having the same problem,ive also had a new clutch and slave cylinder (sachs).. I had no problems with the gear selection what so ever until I replaced the clutch now before start it will slip into gear fine then once started and clutch in its really stiff to get in gear once its been running for a minute or two its fine no problem at all. annoying,, have you had any luck resolving this problem?
