I have designed a spring that will raise WOT shift points in drive on a C-4 transmission. 5000-6000 rpms.
It replaces the stock secondary spring in the governor.
It will be necessary to lighten your secondary piston in the 12 grams to 14 grams weight area.


Only the spring is supplied.
The cost is $20.00 which includes shipping to the USA.
I accept paypal or USPS money order.
