the trans I had with a tf1 and stock 4600rpm governor shifted at 4600rpm at WOT with the kickdown rod adjusted (all slop adjusted out and then backed off 2 turns). the tf2 trans with a stock 4600rpm governor will not upshift at WOT with the same adjustment. the tf2 kit has a lot of low speed 2-3 overlap, even with the restrictor. my thoughts are that the high shifts are due to the heavy throttle pressure spring.
