I have a 03 5.3 silverado
I had the truck programed and had the line pressure turned up but it still doesnt shift hard enough for me.
I have been looking at billet servos but not sure what to get. Will ones for a 700r4 fit the 4l60E?
Anything else I might wanna look into getting?
thanks this site has been a great help to me
get a shift kit, like trans go. corvette servos and a stall and i bet youll be happy with the trans.
Hey man i got an 05 4.8 an i just bought 3200 stall vette servo an 4thgear servo put in my truck yesterday and it makes a world of difference and i dont even have a tune yet im gettin one tomorrow at TRT but even now its bada$$ without a tune
Spend a little extra money and buy the billet servos from superior, Oregon Performance Transmission, Inc. or PATC ( 700R4, 700 Raptor Transmission from PATC, 700R4 4L60E 48RE 4L80E ) Buy a 1-2 and a 3-4 servo and you will not be disappointed. The transgo shift kit is a must in my books. You can also think about doing a Transgo 46mod vacuum shift modulator, it gets rid of the electronic transmission pressure regulator in the transmission valve body.

I dont really wanna have to pull the pan yet. Will the shift kit make it shift harder? Or will just the servos do that?
Also what would a boost valve do?

the servo will help,epecially if you get a stall ,the stall softens up the best of them ,when i took my stall out it shifted like it would rattle youre teeth.with it in i couldnt even feel it shift.hope it helps .i originally did a stall and servos.go with reds suggestion,good luck

Let's face it, the red hair... makes 'em wet.
There is a pin in the Vacuum mod kit that you grind to length to control the shift pressures. Anyone know what length yours are cut at?

so what will the boost valve do?
