4r100 durability.

Another 4r thread ! Yess!

Question is at what hp level are billet shafts a necessity . I'm looking at going for 575ish, a few sled pulls a year, and some passes. Turbo will be here soon. But I don't know how long mine will last at that power.

Not an automatic guy, but if you're talkin that hp, along with the sled and strip, you'll want a bts from the very beginning

Which is the plan. I've got everything but billet shafts now. I wouldnt dream of pulling with this, at that hp level. But I wonder if driving at this hp level for a few moths would be ignorant

I've never been above 520hp...

BUT...

I've never broken a shaft...

Foward drum, center support but never a shaft.

Foward drum is pretty easy to break. Input ,foward drum and the od planet will likely be your weakest link.

LOL...

You would be suprised how easy I drive day to day... The differance is I drive the same speed and style when I am empty or when I am pulling 12-14k...

I bet I dont go WOT 2 times a month...

What do you mean by the bolded? A PI TC and a BTS valve body should help the trans live. Still going with Matt's tuning? In my experience, the hard launches from a dead stop are the hardest on the drive line. Rolling into the throttle will help a bunch. Matt's tuning will help a bunch, also. On my truck, he keeps the torque fairly low. I'm not into huge torque numbers. If I can't pull it with <1000K torque, I don't need to pull it.

I bought it from a friend of mine who built it, he couldn't remember brands but he said it had a Tripple disc tc upgraded clutches and a valve body.

I am by no means expecting it to live long, am just curious if throwing on the turbo would cause it to break the first wot run

what turbo do you have coming? dont see why a turbo would cause that to happen instantly.

I wouldn't think so, especially with Matt's tuning. Matt uses the whole throttle range, not just the 1st 50%. That will help keep power levels from shocking the drive line.

At the very least do a billet input.

You know the power levels I'm at, and I drive the living piss out of my truck too, but, I broke an input shaft, off, inside the converter, and couldn't get it out. I ended up having it shipped off only to find out I'd be better off buying a new converter after what I'd have in this old one.

So lesson learned for me.

 

[PsdPullerJr]

I had almost 4 years of sled pulling and 40k miles on my stock trans, just a factory tech valve body. Upgraded to 230/100s start of pulling year and put h2e on little after halfway and factory convertor went out. Took the trans to rebuild shop and they said it looked like new yet that I could have put a convertor in and kept going. Truck had 98k on it at that time, had a superchip or ts chip on it at 54k when I got it, don't know what may have been before that.

 

[Rideracelivemx7]

when I talked to Brian, most of the transmissions heading out are still only either a factory input or cryod factory input shaft.i don't pull with mine but when I broke the trans the first thing I checked was if I broke the input and it still looked great.

 

[David N]

I guess I'll add as well, I've broken the od planetary as well. I'm probably 550 or so on power. But I am extremely rough on my trans. LOL

 

[Wicked]

My trans is still holding... Stock trans 120k with light mods and then 20k more with the power in my sig... I run it most of the time on the 425hp tune... BTS converter/VB/pump mods is all the trans has.
