While turning around at the end of the track it made a very loud knocking noise. (The guy in the car behind me heard it.) Pulled to the side, looked around, didn't see anything and it hasn't made a peep since. Put it up in the air this morning, pulled back the c/v boots, they looked fine. Drained the tranny and stuck a stick magnet in there and pulled out this:



Looks like it chunked a spider gear. Oh well, been abusing it for over a year now, was bound to break something sooner than later.

Here's the car:

That is super hot!
Good excuse to tear apart the tranny and get an LSD!

 

Ouch!!! Glad you made it home from the track without any problems. Sucks.... atleast you figured out what made that noise. Any idea what caused it? You were launching pretty hard on those slicks but it didn't break till the turnaround at the end. Sorry I jinx'd you

I think it started with the burnout a couple runs before. It kind of felt like it was wheel hopping, but I don't think that was it now. I jinx myself all the time, i'm used to it.

 

wow, u showed that tranny whos boss....

if u drove like that for long....the crank would accelerate past that missing gear, and hit the next one hard, so it would just break em all one by one eventually
that woudl have been kool.

 

I'm kinda thinking that it broke during a pass and spit it out when you fully unloaded the drivetrain to make the turnaround. Just a guess..................

 

yep, good old spider gear........

I EXPLODED two trannys at Edgewater with D15 power and slicks.........

6800 rpm launches do that

We had an Si a couple weeks ago we sold. The kid got a free tranny out of it, he only had it about two weeks. He ripped all the teeth off. Made one hell of a racket coming into the shop.

I was launching at 7k.

 

wait till you see one of my 7800 rpm SOHC launches, on nitrous!

Putting a big holeshot, leaving the others behind.

 

Well, tore it down today and found damaged pinion gears and differencial pin. The one with the broken tooth welded itself to the pin, the other was pretty sloppy. The common cause for this is spinning one tire for an extended period or under a large load. I think i've done both. So damaged gears and shaft combined with 7,000 rpm launches, I think I got off pretty easy.

The good news is I was able to save the phantom grip I installed about 10,000 miles ago. No damage to it and very little wear. I did have to cut the differencial housing apart to get it out though.

And the Exody thin cerametalic disk looked good also with about 50% of the lining left. 10,000 miles on it too.

 

was the carrier split like that when you removed it?????????

It is a one piece casting!!!!!!!!

MAJOR points for breaking the carrier (PG related).......

I want a closer inspection THIS Saturday...........I will drive to you in our area.

No, I cut it apart to get my phantom grip back. I couldn't get the differencial pin out because one of the pinion gears welded itself to it.

 

Please save the parts, I wish to inspect them..........probable PG caused the failure.

Where are you located?????
I'm near Fairfield.

I dont think so.

 

why I wish to inspect..........

 

Seems like you have a hardon for the Phantom Grip. As the de-facto D-series tranny expert, you were not at all surprised that this guy broke his transmission given the way he's been driving it. Then all of a sudden when you find out a Phantom Grip was installed, you're pretty sure that's what caused the failure. Given your distaste for them, I think it's safe to assume that you weren't running one in either of the two transmissions that you "exploded", so why would this case be any different?

At any rate, it's pretty clear you have your mind made up as to what caused this failure, even before seeing the parts in person.

 

Have you had lawsuit's filed against you for stating your first admenmet rights??????

This issue is WAY deeper than you know.

I wish to view his tranny to prove my FACTS right or wrong. I have 5 cases from road racing where the PG aided in failure via extra sideloading.

I was passive until JB's crew tried to run me off the road just after a Mid Ohio event.

Still, I;ve never had to try to sell my daily driver/race car on Ebay.

 

i wanna rebuild me tranny where can i get parts? its a y21 and recently i lost reverse check the linkage it was fine so now i wanna drop out the tranny. thing is its my only ride to work so i figure i drop the tranny in one day and rebuild it i have not time for lookin brokin parts anyways ill take a pic damage area or gear

I'm a little confused when you say you have to prove your facts right or wrong. Facts are always true, that's what makes them facts. Sounds like you're not too clear on the issue.

I'd love to know who in "JB's crew" tried to run you off the road. I've known him for many years and this is not something he would condone.

While we're at it, here's a fact for you: You do not know why he wanted to sell his race car on eBay.
