Big edit

hey guys, ive been looking into o/d trans and wanted to ask and make sure that unlike a 700r4 a 2004r will do a wot 3-4 shift right? No need to get inside the valve body for that

I believe it will.

I don't recall any issues with WOT shifts when my transmission was stock. I have installed a Transgo HD shift kit in it and have no issues with any shifting.

To be fair though, shifting to OD, especially the .67 ratio of the 2004r, never makes much sense to me. Nobody is shifting their 1000 hp turbo LS combos to OD when they are wide open in front of 4l80's, nobody shifts their t56 into 5th gear (1st OD) at wide open short of someone with a vette who wants to cruise at 140mph and not rev to 7000rpm for hours on end.

The only case I can see OD at WOT as a valid use on a 2004r is if you have one with a 4000rpm shift speed due to it having a granny governor and trans is not actually letting the engine spin higher so it shifts to OD. A 4000 rpm governor makes sense behind a smogger 305 or 307 that actually runs out of breath at that RPM, but if you have any head work, intake manifold or a never engine like an LS or LT your peak power is going to be more near 6000rpm anyways so letting the engine spin is going to make the power and negate the need to be in OD and WOT.

You never need a WOT shift into OD unless you're land speed racing or are building a use specific vehicle with a crazy low granny gear ratio.

Cop cars are setup to shift into OD at WOT for high speed pursuits like my P71 which have either 3.23 or 3.55 rear gears.

Bufford..... "nobody, nobody makes sheriff Bufford T Justice look like a possum's pecker.

Junior.... "accept for that..."

Bufford..... "shut yo *ss"

If only OD was available in cop cars back in 1977, during his high speed pursuits, bufford could have been kickin up mr bandit's *ss around the moon back then.

I mean I've done it... and even with a 2.29 rear gear. Thank goodness I had speed-rated tires.
I have no idea how I made it this long in life?

Unless you have upgraded clutches (quality and quantity) I would avoid it at all costs.
