damn i was hoping i could get a new shaft and stick it in there and do some cleanup...guess not?

and yes it looked like that...same spot...looks like there is a oiling hole in the shaft right where it broke..

 

I agree that a billet shaft is the fix here. What kind of power are you pushing with your combo hp, et, and 60ft? I personally like to see a billet shaft used in extreme use and especially with good sticky tires at the track. Vince

 

both planets are probably chewed up, as well as a bunch of other stuff. When mine broke, it took the case with it too, I had to use a sledge hammer to get that shaft out.

 

dammit...car prolly makes about 600rw through an auto...close to 700 if it was a stick...
60' in the high 1.3x
1/8 6.30's
mph 109

 

holy crap!

 

don't even waste your time and money with a hardened shaft, get a billet one.

 

yeah ive gota talk to my builder...i know few other that have the same i had that havent broken them yet...i guess repeated beating on it and back when i had wheel hop problems is when i started the damage

 

I broke 2 hardened ones in 2 months, but i'm alot heavier then yours.

 

With that being said I would get a billet shaft. Also wheel hop issues will really shock the driveline and cause multiple failures. A billet shaft with 1.3 60's will probably be a very good investment. Vince

 

That looks exactly like my failure, mine snapped right on the 1-2 shift also. I'm on mickey thompsons... Twisted apart at the oiling hole the same too and took out the rear planets and the tailhouse cracked also... Upgraded to GM 5 pinion planets and went with a hardened output shaft as it was $150 and the billet was around $400-$500 and I'm just full boltons so hopefull the hardened shaft holds up for a while... My local builder charged me for just the hard parts no labor and it cost me about $900.... g'luck with yours man!

 

I had similar problems when my 4l60e started taking a dump. I was told it was the forward sprag, but now I wonder if it was a shaft. I sent it out to a builder to get fixed...come to think of it that was well over a year ago. I ended up building a 4L80e and put in since I never heard back from him.

I think I'm going to have to make a drive out to California to get my trans back one of these days

Anyways good luck man, breaking shafts and hardparts means your making the power, well done.

I wish the reason i was breaking **** was because I was making too much power, but i'm just full bolt-ons still On the broken shaft my best 60' was only 1.7 and best 1/4's in my sig.... sooo yea...

 

I wasnt going to play that game, I had already broke 2 4L60e's with just bolt on's and street tires. Hence the 4L80e. Pretty bad when a bone stock $100 4L80e holds up better than $1400 4L60e.

I just spend big money getting billet parts for my 47RE in my Cummins, ouch...and people complain about trans prices for gassers...

yeah glad it was a hard part...i gota ask frank to order me a billet one...i cant believe this one helt this long now...
i hear a lot of truck guys braking input shafts also??? if so they make a billet one of those? might as well...
ive already got the 5 pinion planataries...

my 60'e broke when i did a cam...lost 3-4 then i sent it to be built..this is my first problem since

 

Yes, they make billets for the truck guys, but we still snap them.

I think he is talking about 4L60's

 

Rossler has a billet input shaft. But most don't break the input shaft, it is the input drum that breaks more often.

 

Mine broke on launch and it was the input sprag assembly.
