Shit over 100 dyno pulls and well over 600rwhp and plenty of street races, joyrides, practice launches and plently of power shifting. Maybe something was wrong with your step up or your driving to be breaking them every 4 runs. I still have the same tranny only came out because I wanted to give the liberty a try. We'll see how she holds up.

Ernie, I thank you for your info!
I hate to waste money so I am not sure what I will do yet. I dont think my tranny is even bad just looking at ideas and seeing if there is a chearer out. I may see what kind of warranty or if they will let me be a test car for it. First things first. So the things I am wondering is: 1. if I brace the tranny case in the broken areas 2. the treatment of the internals 3. if they can make a billet output shaft Will this hold? Not sure what the brace fab up would cost me but 1400 for tranny work and 700-900 for output shaft would yield a 2100-2300 kick ass tranny "IF" it will hold. |
BTW our Liberty Tranny has custom 300m output shaft...

Im not the only one it happens to. Ari Yallon breaks a stock tranny once a race. He cuts 1.3 60's. The lanuch is where your gonna break. Dyno pulls and driving around is fine. When you put a dog tooth gearset in our shit fd box, it wants to expand, thus flexing and cracking it. I don't know your tranny setup so I wish you luck with it. My main point was simply if your gonna drag race, you'll need a tranny to handle it.
Nobody is saying its bulletproof and yes I agree if you want to drag race spend the money and buy a real tranny but they are not cheap. If my stock tranny ever broke I would love spending 200 bucks for another used one if it would last as long as my current one has. Much rather spend that 5 times then the 3k + price for one which is also not bulletproof. If is a drag car dont waste your time but if its still a "real" street car your compromising a lot of streetability. |
I broke a transmission once.

racing it or humping it with your 350lbs self? :lol: :lol: |
I don't remember but I'm sure I was doing something ignorant.
|
I have broken 2 transmissions. Both times 3rd gear lost all the teeth. The last one cracked the case in a few places
|
So do the S5 trans have the same problem as the FD trans when you start making that kind of power, or are they any stronger? B/c I kinda had the same idea as sk8world with my trans. I'm gonna be building a new motor, with a larger turbo this winter and there are thought's of having liberty faceplate 2nd, 3rd, and 4th, and installing new bearings also. Was just kinda wandering...

Stock box 1st gen running 9.2 and 1.3 60ft
https://www.rx7club.com/rotary-drag-racing-167/fiebre-jr-rx7-new-look-902564/ Surely there is enough demand for a gear manufacturer to make a stronger 3rd gear to replace the stock item. |
So my input shaft is bad need another input shaft and cluster. Anyone?? Liberty cant move foward till I get this too them.
|
On the subject of casings, the below rx3 ran 8.3 on a S5 turbo box with mazda casing and albins internals.

Your going to love powershifting that tranny.. Enjoy...

Sk8world,
I think I mentioned to you I've had all the metal treatment done by Liberty. It has held up until I shift from 2nd to 5th and I twist the cluster shaft. Question rather it needs treated since I think it just holds 5th and reverse gears. I'm real curious how the faceplating drives on the street. I don't drag that often but lots of dyno and street pulls at 560-630whp. I figured you had plenty of cluster shafts in old trannys???? I was actually going to PM you for one. Let me know how the faceplated gears drive on the street. |

Thanks Enzo! I question the output shaft. By looks it doesnt apear differant metal than the stock output shaft???? Can only see the end but I expected it to be a polished look. I called Paul back at Liberty and he said it was the upgraded shaft??
You won't be able to notice the difference unless you open the box up.. If paul told you it's in there believe him that's it's in there.. Now go bang some gears.. :) |

I turned up the boost on the car and made some decent power, more than I ever made. I take the car down to Maryland and the first pass, broke the output shaft. It's the first time I ever broke one. Glad to see you upgraded the tranny! :)

Sk8world, while it does shift pretty effortlessly just go easy on the downshifts as it does not like those one bit. |
