tko600 to t56 magnum for autocross

[sean69cam]

Making some changes to my autocross/roadtrack 69 camaro(ls3 427 650Hp). Having trouble with tko600 missing shift to second at higher rpm. I have to either shift early or shift slower to let rpm drop. The trans has the carbon fiber synchros that were done about 3 yrs ago. Seems like getting worse. So debating freshening up or go to t56 magnum. I am looking at a race prepped t56 but the gearing has me thinking. I am used to 2.87/1.89/1.28/1.00 with the tko and 3.73 rear. The t56 has 2.29/1.60/1.21/1.00. I want to keep ability to pull strong out of corners in second. So not sure how would like the lower 2nd gear ratio. Anyone with experience with these gears?
