Manually shift auto or
Seem to get more punch on the manual.But better dial ins on auto.700R4 lt1 pretty much stock .In the future prolly going TH350 with a fresh motor.Reason im asking got in a pretty big debate about this.Most of the people i see raceing are shifting theres. Im not worryed about the big bang theroy. Thats why they have tranny shops
Manually shifting is terribly inefficient.
For a stock (or lightly modded) Lt1, stock shift points should be pretty close to optimal.
If you want it to shift harder, install a shift kit
Factory shifters you can't do this. This is also a regular automatic valve body tranny.
Let yours do it on its own.
