I hope the tranny can handle the heavier truck either way ( S/C'd or not)

"How Do You Bulit Proof Your Tranny?"
Sorry to say but there's no such thing!
I have had my 4R70W built/built again with every part out there/added a PI TC and added some other parts we found on the market.
And yesterday it went out again. No 3rd or OD
If you make enough power it's going to break.
I'm looking in to a BTS 4R100 now. Maybe that will do the trick.

Built Lightning block,
stage 3 ported heads and Comp cams,
ported L intake manifold.
2.3 Kenne Bell blower at 16 PSI
New BTS 4R100 tranny
100 shot Nitrous
Best 1/4 to date
60'-1.6
1/4-11.76 @ 116.17 MPH
Ya,,hahaha and I should have started out with a 2 wheel drive to.But I never planed on making a lot of power when I bought the truck.
And when I had the tranny done I thought, well if Johnny Lightning can run a 4R70W, Then I could build it up and be ok.But,,live and learn,,lol.
I wanted to use my tranny because it's lighter. Didn't need to add any more weight.

Oh phil but there is a production car that the engineers worked 6 years on the tranny so hold up to the 1001Hp it produces. Bugatti Veyron.
But for our trucks NO.
Tazz
if you need a tranny harness for a 4R100, lemme know. I've got a spare one, just gotta find it. I did the swap from 4R70W to 4R100 during my whole buildup winter before last
no problemo! shot you a PM with a bunch of info. you will need the tranny harness. the 4R100 is setup totally different than the 4R70W so all the sensors, etc. are a bit different.
who exactly is your tuner/builder? I'm assuming somebody in the tri-state region? you gotta get that truck to one of the DelVal meets coming up!
What is the maximum HP you can apply to a 4R100 with a FTVB only (stock converter, etc.) for the street and expect it to live?
I don't think there is a resonable number that you can point to that will say at this point it will fail. Each tranny is different and driven differently. There are alot of people drving around with trucks in the 380-400+ HP on stockers. Mine was rebuilt by Ford once already...387/469 the last time I was on a dyno.
I just finished having my mother built (after joining the VBC). KB 2.6, Ross Pistons, H-beam rods, ported heads, stainless valves, good springs, head studs. I am hoping for 450-500hp. I am planning on a FTVB and a Moroso pan. Just wondering if I will be looking at transmission issues....
too funny.
the 4R100 is pretty stout. you should be okay with 450-500 hp to the wheels, but its a hard call to make. some guys trannies have gone when they were bone stock, other guys have put some serious power through them. a number of L's on NLOC with the same tranny have ran 10's and 11's on the stock trans with just a converter and valve body.
i'd keep it in the back of your mind for a future upgrade down the road, but I wouldnt be too worried about killing it in the first 100 miles
