i just converted my 89 SporTruck to an AX15 and am now having issues shifting into the gears. the transmission was rebuilt, new clutch and resurfaced flywheel, bleed it mutliple times. it will work fine one minute and the next not want to go into gear. sometimes pumping the clutch up or just waiting for a few seconds and trying again and than it will barely let me manhandle it in. any suggestions?
