Made 3 passes at track yesterday then within the first 60 feet of third pass i think my input shaft broke on trans it had a small amount of trans fluid come out around the bell housing where it mounts to engine.?
When idling from time to time you hear a small clatter noise sounds like bell housing area and convertor is not enguaging park and nuetral work fine. the one in trans was stock but was suppose to be cyrogenicly treated..

time to upgrade to the TCI billet input shaft, I did mine at the same time I did the build.

BTW I still have my stock one you can have if you just need to get the car back on the road.

Time for a TCI hardened input shaft! Talk to Chris from PTC for them, he has very good pricing.

If you can swing it get a better TC and PA trany pan, now is the best time to upgrade it since everything has to come out.

Sounds like it's input shaft or pump gears for sure.

I can get you very good pricing on the hardened input.

Ah hah! There he is! Chris to the rescue!

had this same shit happen recently AFTER level10 built my transmission
bits of the shaft look like a stock one but that definitely sounds like your problem.
New input shaft, make sure it's actually billet, I'm locked in a battle between level10 and my tuner right now between whose fault everything is and how all this is getting taken care of.

I was told when they built the trans that they used the stock input shaft and have them cryo treated, I am not sure that i like that anyway so i am going with a billet one who says the stock one didnt have a weekness allready we will know within a week once the trans is out for inspection. hope its simple..the pump gears in my trans are suppose to be cryo treated too..

would it be a benefit for me to cryogenically treat the TCI M300 input shaft?
I dont know that it would help much but would it hurt? if it would give it a little more strength i would try it..
have heard that anything over 550 RWTQ and and up gives the input shafts and 3rd gear band hell on the 5R55S.

Most of the companies DO NOT use a billet input shaft. They give a line of crap about 'cryo treated' and 'hardened' and other BS.

The simply truth is the input shaft is one of the main weak links of the 5r55 and a stout billet piece is the ONLY thing I would even try in drag applications.

Personally, I wouldn't use any 5r55 no matter built by GOD for my kind of drag applications, but if you are going to try to make one last for a minute - make sure the input shaft is stout - I'd also make sure the gears and TC are as strong as possible. Those 3 areas are the shit spots for the 5r55.

TCI shaft here, no issues so far. Also have the stock one if you need it to get going.

Hope you didnt mess up anything else; the shaft probably came out and hence you're leaking some fluid. Or some shit tore up when it broke. Yuk.

I doubt if you could shear the input shaft without tearing up the pump. I hate to say it but I think you are in for a rebuild as well as a new input shaft.

That's what happened to me
Sheared the input shaft, it got jammed in the converter and it tore up the front pump
Luckily that's ALL that happened and everything else runs now, I just need to chew level10's ass out now since the FIRST time we talked on the phone they assured me it was built with "all billet parts"
and then once my "billet" input shaft broke I requested a BILLET input shaft, and got the same stock shit back
I'm not using them nor will I recommend them again. Took them 3 weeks to rebuild a transmission with 50% stock parts to begin with.:horseshit:

that sucks!
I will cross my fingers and toes and see what it looks like after the trans is droped out hopefully by friday i will know hope it didnt trash anything more than the shaft. they told me it depends on where the shaft broke the big pain is its expensive as hell shipping transmission
