tonight she let go on me. it was my second run with the new cam. first run all I did was spin the 60 to a 1.93. my second pass i hooked up good (was probably low 1.6's) and when i shifted it into drive she banged and lost going into all gears. does this sound like a pump or converter issue? I still have warranty on this but it all still sucks.

Sounds more like a pump than a converter, mine did the same thing a while back.

well i talked to the trans builder and he's thinking its pump or converter. sometime next week when i get it up i the air ill run it with the return line disconencted and see if it's pumping. either I broke the converter hub or the pump is toast. he's thinking it's the converter. I'm hoping for that.

two problems.... well after hooking up HP tuners I could see that the trans input shaft isnt getting anything, so the converter isnt engaging that. but the trans also rolls in park or any other gear and the speedometer doesnt move when i rev the motor. any ideas? I cant get ahold of my trans builder right now

Maybe you have a broken output shaft or a broken rear ring gear. This would explain why you do not have park or vss signal.

true, but why would the trans input shaft not be turning. still cause of the converter? thanks Vince

Well I don't know for sure if your pump or tc are even bad. It reallys sounds like what I stated earlier. Did you tell your builder that you do not have park, vss signal and movement?

if just the converter went bad could i still lose park? is there any way that the transmission is actually in park when it's locked down to the motor? tomorrow night I'll hopefully see something

I don't see how a TC would cause you to loose park. Park happens after the TC inside the trans. My TC went bad a couple weeks ago and it still held park.

Maybe you broke the converter to flywheel bolts that would explain why you lost park and have no input shaft movement. It is unlikely but possible and easy to check by pulling the inspection covers.

I don't believe that this is true. The parking paul engauges directly to the rear ring gear which is splined to the output shaft. Broken tc bolts will not cause this. The only other thing that might cause this is a broken rear end but you should have a vss signal if this were the case. Vince.

well my builder had asked if it was a broken rear end. but no noise was made when it broke other than what it sounds like to hit the rev limiter. the car still pushes around fine. i should be removing the trans tonight and I'll find out more of what's going on. if nothing is obvious theres nothing I can do with it but let the builder handle it. thanks

UPDATE: VINCE NAILED IT: what sounded like a rear end problem tonight ended up being a broken HARDENED 4L65E output shaft

Wow. That sux. I feel your pain though.
I went with a TH400 and now I am breaking everything but the transmission.
