my 6.0 is going in soon along with my 3200 converter, so to firm up my shifts I bought a transgo hd2 shift kit, and Im also looking at the raptor 4L60E high performance intermediate billet servo that is rated for 35% more holding power between 1-2 and 2-3 shifts, and to go along with it Im also looking at the raptor high performance overdrive billet servo for the 3-4 shift which has 50% more holding power. So what Im getting at will this be to much for a stock tranny? I want to make this thing last as long as I can ( I know thats asking alot but Im trying) I really need my 3-4 shift firmed up.

just go with the vette servo over the billet servo. The billet one will make the 1-2 very very firm

+1, everything that I've heard about the billet 1-2 is that the shift is too much, and it will be totally neck breaking with that servo and any washers installed with the HD-2 kit.

Im going to be building up my 60e here soon. Im pulling it and bringing it to a builder and he's going to charge me 450$ for shift kit, servos, 3-4 clutch pack, sprag, and beast sunshell. I know it wont be a bullet proof trans, but it will hold up to what im going to be throwing at it.

If I were you thats what I would do also. These are just weak links that fail more often than others. Since your going to be pulling your trans, build it up a little better while you have the chance

Im not going to be pulling my trans..., what about the overdrive billet servo? my 3-4 shift practically blends into each other its so soft

I would add the vette servo and the Sonnax 4th gear superhold if your still not satisfied have your tuner bump up the line pressure a bit.
