Also how many shims should I put in? Stock tune and torque convertor. I want a crisp shift but dont want to break my neck at low throttle.

 

I put 1 shim in and could break a neck at low throttle.

 

I left my 1-2 accumulator stock: no shims, no changing springs. Between the servo addition and the hole drilling, I have all the crispness I need (or want)

 

Want to add that I was able to "tune" this neck breakage low throttle shifting out with HPT. Feels perfect now.

 

Thanks for the info, guess I'l order my parts and put them in on my next free saturday that I dont work.

 

I am wondering how long it takes to change a 2wd 4l60e to a 4x4, another person on here told me an experience tech could do it in about 15 minutes. PM with answer, because I may forget this thread plz.

 

One the bench ready to go,a good tech can swap shaft out in 30 min.If your dealing with a very clean trans exterior.

 

Get the transgo hd-2 kit it is the good one with all the bells and whistles.

 

What else does the hd-2 kit have that the other doesnt and how much more involved is it to do.
Right now I'm looking at getting the shift kit, crovette servo and longer rod, saperator plate, and aluminum accumulator piston. (nothing ordered yet)

 

What about an OD servo?
