I'm putting a ss3600 stall in my 4l60e along with trans go HD-2 shift kit and was wondering how many spacers to use and which size drill bit to use? Thanks

 

NONE, IMO drill the holes on the smallest setting.... Also you putting in servos while your thier? Billet or corvette?

 

Corvette servos

 

Then IMO do like i said, that is exactly how mine is setup and it shift damn good, nice and quick and not violent on the shift.... Also i have been rocking that setup for about 25-30k, it is still shifting fine at 6800-6900 on a regular basis and it has a ton of track passes on the setup...

 

I didn't have a stall . . . but I did not use any of the spacers . . .

I drilled the 1-2 shift hole to the second largest, and the rest to the smallest hole

If I did it again . . . I would have them all to the smallest drill bit.

I did use one spacer ring on the servo for the band.

 

on my old truck i had an HD-2 with all the holes drilled to the smaller setting, a corvette servo, and 1 spacer ring on the servo. with my SS3600 it would shift pretty firm, however it did not chirp the tires on the 1-2. it would do that when i had the TT3000 though.
