There is a hole that needs to be put in rev piston that helps.Put the kit in u can put in 1 geat at 6000 grand, stuff may blow up ..lol He said manual mode. That makes the tranny full manual. You have to shift like a stick shift.. Unless ur on Race track all the time dont go manual -2 shiftkit is best.
if your having to install some sort of "shift kit" for each 700r4/4l60e you build, theres something wrong.
ive done plenty without any kind of modifications and they worked just like theyre supposed to.
the most common "kit" that gets installed on a 700r4 is the sk jr by transgo.
to the OP, the best booklet to get to help for rebuild would be the ATSG blue book. do a google, theyre easy to find.
