I have a 904 with a Turbo Action low gear apply manual valve body. Nothing special on the rebuild, 3.8 lever, 5 clutch drum, accumulator blocked.

Trans shifts fine but there is a lag between the 2-3 shift where you can hear the engine increase slightly in speed between the 2-3 shift.

What can I do to apply 3rd faster?

Please let me know if you need additional info.

Thanks.
