Setting Shift points on a 4L60
How do you increase the auto shift point on a 93' 4L60 (non electronic)? Its currently shifting at around 5600, would like to get it up to 6000.

Your tranny guy can help you with this. Theres a govenor recalibration kit from B&M that cost about $30 bucks that will do the trick. You just pop out the govenor cover on the drivers side of the tranny, pull out the valve and use which ever springs/weights the kit tells you to.
Or you can just shift it manually.

As for the manual shift, I think I might need a shift kit. The manual shift seem to be real slow at WOT.

I tried the B&M kit.
(you need to be luky...)
I changed ONLY one wheight on the governor and i choosed the one (lighter) more similar to the one removed. I haven't changed any spring.
My WOT shift points changed as expected (in the right desired direction) but also part throttle shift point changed expecially the 3 to 4 shift.
Now I need to go over 80 mph to shift in OD.
As per B&M instructions is a "Trial and error" method and since removing the governor on a C4 is not so fun....

Also, I overhauled my tranny locally and put a Transgo Shift Kit in and shift manually at 6300rpm.
But it would be nice to set it up to do it all by itself. But, dont have time here.
I am in Guam, be home soon if you want the kit.
And thanks for the help at the track that night when I blew up the water pipe going into the pump. Thanks again.
FWIW guys, James helped repair, gave light to the problem at the track then followed me home to make sure the repair (RTV and allot pf prayer) made it home.
