So I have a thought.
My 93 Z28 is pretty stock for now, with 117K miles.
Stock tranny as far as I know.

Would it be bad for me to leave it in neutral, rev it to 3-4K rpm, then straight into drive? I know its not a T56......but....I dont have one and want one
Will this kill it really quick? Or can I get away with it every now and then?

 

Never tried it on a 4L60E, but this function has been locked out since the late 50s. Do not do it, it is silly. FWIW.

 

hmmm, so it know not to let it shift if its running too high of an rpm?

 

I lost 3 trannies doing that when I was younger. Stupidest thing in the world to do.
