I recently replaced 1st and 2nd Gear Syncros in my 915 Tranny. Put everything back by the book and tested before reinstalling. Finally got the car back together this AM and it will now not shift into 5th....I have adjusted the coupler per JW's instructions. 1st through 4th, as well as rev shift like butter, but I can't get it into 5th....This is really driving me nutts after 3 weeks of weekend work....I have not tried to force it into 5th yet, but I am almost at the point of trying before I have to drop that darn engine back out...Where did I go wrong? What are the potential reasons why it will not go into 5th??? Please help!!!
