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
Vac mod rules, I have mine in a box for when I tear down my 65E.
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?

Corvette servos are fine.. I have installed a Super Hold 2nd servo once and it was Way to much ... Customer didnt like it... As Far as shift kit... Trans-go HD-2 ... Sonnex is the maker of the super hold stuff...

dale would tell you to tune out all the torque managment!
i went ahead had all the tourqe managment took out and line pressur eraised to 100%
i cant tell a differance im gonna just get a 1-2 servo
i wouldnt keep the torq managment off and pressure at 100 for too long, unless you wanna rebuild it. IMO
mine is at 80 and it shifts great.
Thats alot of pressure! it will break!

you mean with shift points right? I thought that you could only change shift rpm on that table. I think Allen told me that, maybe I was wrong.
But he did say there is a myth that you could store 2 different tunes with that button, and he said that the myth was B.S.
You can crank the line pressures so high that you can crack the tranny casing..only if you wanna... You can tune in two sets of line pressures with the Tow/Haul button. I'd do a 65 regular; 85 when the Tow/Haul button is pushed... If I wasn't going to have a complete tranny build done, I would for sure do a Superior shift kit (or Trans-go HD2), 2nd and 4th billet servos, 1-2 accumulator piston, forward clutch accumulator piston, separator plate, and the high rev spring kit. I haven't heard of may people drilling out the 1-2 feedhole any bigger, but do go ahead and drill out the 2-3 feedhole .110 bigger and the 3-4 feedhole .125 bigger...
