SC + T5 + 400HP=?

Simply said we comletely disagree. I understand there are weak points, but my tuner, myself, and the shop I take my cars to all have rocked t-5s at my power level without worries. How you drive affects EVERYTHING and powershifting ups those odds. If I have ponied up the dollars already for the engine build dont you think I am expecting to continue to spend money, and what is the difference if it fails or I take it out before it fails? Does that make the new tranny cheaper? NO. Also, if the stock clutch is still holding it should make one think..hmmmm maybe driving does have something to do with it...

Although you may have "rocked" t-5's at your power levels...there are far....far more that have broken them with less. I don't disagree, how you drive can absolutely effect the trannys longevity. It won't however ensure that the tranny will be safe at higher torque levels. Because of the previously stated tranny weaknesses, powershifting with near stock power levels loads the tranny in such a way that it put's extreme stress right at the heart of the trannys...eh...weakness. Now when you increase your torque levels to an extreme amount you are able to stress the tranny much in the same way...even without powershifting.

It's the same reason Joe Shmoe takes his friends out for a ride in his basic h/c/i stang and punches it while in 3rd going up a hill. Kaboom goes his tranny and he's left wondering WTF just happened. Perahps not the best analogy, but you get the point.

If you take your tranny out now while it's still good...you can typically get 500+ towards a new tranny setup. That sure as hell makes the hurt much less. Or, you could do what I did and wait until it finally happens to you. No, I have never powershifted. No, in turbo form it has never seen the dragstrip. No, the car has never seen slicks. Yes, the tranny went kaboom rolling into 3rd without much effort.

As far as the stock clutch goes...your best to keep it in. I'd venture to say that even though you may think it's not slipping....it is! This is most likely keeping your t-5 amongst the living.

powershift that thing a few times and let us know what happens.

It is now happening in 2,3,4,5 gears and sometimes 1st...i don't think it is my syncro's.

Why don't you just buy a better tranny now (before the power). You're already having problems with the stock one...get rid of it. Then save your money and add the power adder. The peace of mind will be worth it.

its not your tranny, most likely if you have an aftermarket shifter the stops are too close and its popping out of gear, or, your clutch/quad/cable is dying and its moved the engagement point further down so your gettin off the clutch faster than youre shifting into gear causing it to be rough/grind

I have an MGW but it is not the stops, and there is no play in the clutch pedal it is firm the whole way down.

To re-itterate what i have said before...it does not happen too often but anywhere from 1-4 times in a 10 minute trip it will not go into gear. I go down to push it into gear and it wont go in, so i hold it there until it finally pops into gear.

My boss said he thinks the clutch isnt engaging/disengaging all the way and I should check my fluid/cable.

 

[DRock9]

Anyone confirm/deny?

see if double clutching it works. if it wont go into gear, let off the clutch, push it back in, and try again. let us know what happens

Bingo!! The key to having a t-5 survive is having the clutch be the weakest link rather than the trans. Right after I put in a CF DF, I took mine to the track and boom went third! Bye bye t-5. If the clutch allows some slipage then the tranny will survive a much longer time. If you switch clutches and keep the t-5, don't put in any crazy high friction type of clutch. Good luck.
