T5 Carnage Pics Part II

[WhiteDevil]

Well as most of you know i split my main shaft in half a couple months ago, and i fixed it and the car ran good for about two weeks. Then when my spec I clutch was done being broken in i decided to punch it. BOOOOMMMM. Well i took almost half the teeth off my 3rd mainshaft gear, and messed up the cluster gear too. Damn weak ass T5s. Heres some carange pics. Enjoy

What 3rd gear should look like(its the smaller one)

Here is part of 3rd with the teeth all broken off

Another broken pic

Well I can definetly blow up a tranny better than you!

So what are your plans now? G-Force?

I like the Blair Witch hand prints on your side skirt

 

[mytight95]

you got the dreaded third and countershaft,.......lol


you can pic up those gears in a package deal off e=bay for 150, don't take this the wrong way, but when you redid it did you set you endplay as per the instructions on the video... You shouldn't have had trouble with it this soon.... just my .02

i think T-5's are a little underratted. They can take a pretty good beating before blowing up, maybe you didnt install something right the last time.

My T-5 is still going after 120 miles with the 418. It seems to get louder every time I drive it tho.

Yes, i did. I got a shim kit and set the end play. With my dial indicator i as not even seeing .001 of endplay in this thing. I really dont think it had anything to do with my work. I mean people bust teeth of 3rd gear with much less power than im making. Ive always been told that 300rwhp and a T5 werent the best. Plus the extra hard grab of my new spec clutch probably wasnt the best for those puny gears.

 

[mytight95]

sounds right them, you have 298 rwhp, i just noticed that, between that and a spec clutch if it is anything over a stage one, it is wreaking havoc on your drivetrain. stage 2 and above don't have the spring in the disk i don't think.... that absords the shock of say a powershift etc...


what are you gonna do with it...

i was also gonna ask ifyou checked gear engagement between the gears, you can shim the output shaft as well, to make sure the gears are lined up perfect, and still shim the back side to get the desired endplay....... Tricky stuff to get one just right, i know, believe me i have messed up one of my installs and three shifts later i was missing teeth on gears....

When you say punch it did you just floor it or have you been power shifting? My tranny has seen a lot of WOT with the blower and it is still holding up.

 

[WhiteDevil]

Mytight95- I didnt really check the engaugement of the cluster gear and the mainshaft gears with anything accept my eye. They appeared to be pefectly meshed and centered on each other. I never removed the cluster gear, so i didnt play with the endplay on that. I used shims on the input shaft bearing retainer to set the endplay. Which was less than .001 on my dial indicator. Also i drove the car for two weeks and put 390 or so miles on it and it shifted smoother and was quieter than it had ever been, so i just think it was the stress of the spec and the power im making

S/CBlack95GT- Well i actually punched a few times. But i this happened during some gear banging. I had hit 3rd hard the day before and it freakin broke the tires loose really hard. Then the next day on a freeway onramp i hammer it in second and hit 3rd with not really a powershift but somewhere in between adn boom this happened.

 

[mytight95]

if with the power you are making you keep the t-5, you are gonna have to clutch,pause, shift, pause, release clutch........lol


its not really the hp its the torque, these trannys are rated at 300 for the gt in torque, and you are making around 380 lb ft of torque at the flywheel so..... you are pushing it, there are some other things you can do to strengthen it if you decide to keep it,

I put one together for a friends car he powershifts every shift, has held up about a year and a half.....he only uses 1-4 also cause it's a race car.....but on that one we took every other tooth off the blocker rings, run synthetic fluid in it, and actually put a little preload in it with shims, put it on jack stands and ran it long enough for it to wear together for the track..... has held up good....you gotta remember the specs for the endplay are setup for general automotive use, not really high performance, and under a great deal of torque you get what they call spreading between the countershaft, and third gear, which minimizes how much of the teeth are making contact, they are easy to break when only like a quarter inch of gear is actually meshing vs. the entire thing, 380 lb ft, and 1/4 inch to hold it don't work...

Yeah i totally understand. Ive heard about the shafts spreading especially in 3rd gear. Which is why the 3rd gear busting is so common. Im going TKO-500 in the next couple weeks. Just thinkin ahead cause i got a 347 going in next summer. And i know myself, which means there might be a little spray to go with that, lol. So i just wanna have something that i can trust, if you know what i mean.
