Default So my torque converter just blew up..

I swear I have the worse car luck lately.. The LT4 is up on jack stands now as I try and figure out why its been misfiring.. then, as luck would have it, on my way home from work driving the LT1 and the fn torque converter literally blew up 3 blocks from home.. I just limped into the garage.. Both vettes are now down.

A Precision Industries Vigilante converter will never blow up. Full throttle lockup in third gear and the converter hits like a gear change. Probably a 1000 10 second runs on the converter.

I was at a stop sign, when I went to accelerate I hear a loud explosion.. like Boom.. not unlike a firework. Then I hear metal on metal.. sounds like the stator or turbine went boom and disintegrated.. I can only hope the fallout didn't ruin the tranny.

I have no idea who made it, I assume it's stock.. will find out tho

I wouldn't care. Time for a totally rebuilt trans. NFW would I trust that the trans itself is still good or that there were no metal pieces that went into the line and into the trans.

I'll polish the chrome after I get the motor running. Car might be immaculate but if it doesn't run, what are you going to do?

I have used Rossler before. Recommended by LPE and their trans lasted 4 years and some change, IIRC on my 91 F-body when it was the DD. I beat on it every day but the winter when it comes to ramps. Broke the sun shell gear and when it was apart, it wasn't that badly worn. It won't be cheap as a Jasper trans but you get what you paid for.

Damn dude I am sorry about that

Definitely do a somewhat built trans on the car. Have you looked at the fluid to see if metal is in it?

Why bother? Would you dare to simply slap a new torque converter and reuse? I would not

I think you need get it on jack stands and try to determine what failed. I never heard metalic noise from a failed converter. Whine as engine was revving and car was creeping. 700s can have the pump bushing can fail. Broken flexplate could pop then make a **** load of noise as car creeped along. The hub portion clashing with the part bolted to converter.

Nope.. haven't even looked. Been pretty bummed out about it too. As it happened I already started figuring where I'll find the $2k it'll take to fix this. I don't do trannys and have no lift etc.. don't wanna fight it on the ground of the garage with Jacks and Jack stands.

It just seems like every time it looks like a good time to paint my black car something happens and I spend the money somewhere else.. hard to justify spending so much on such a vanity.. then stuff like this happens..lol

it makes the sound when the engine is on at all times.. in and out of gear. Car moves and even shifts fine.. I'll make a video now.

Just a thought If the TC blew up, how did you make it home? TC is bolted to the flex plate and attached to the input shaft It's a fluid coupler.

That is loud. Converter failure and drives and shifts fine don't normally go together.

Run it with the serpentine belt off? I'd try it since it's easy and quick to do.

I am under the assumption that if your torque converter grenaded you aren't moving anywhere at all.

Any difference starting in N or even when shifting at idle?
