Another 3-4 clutch pack takes a dump Not even at the track but on the way the 3-4 clutch packs decided to not function properly..
Little rundown..
Car weighs 3000 lbs. Has tranny cooler. Fluid is new and pink. 4.10 gear 26" tire
Install used engine/tranny with 45K on it into my 97 bird.
Put 2K miles on it stock verter.
Added QTP LT's, LS6 Intake, ASP Underdrive and YPT 4400.. broke trans pump fixed that.. and car ran GREAT!!
Put a few hundered miles on it.
Removed torque management.
Put a few more hundered miles..
Time to double check the tune... I was racing today and didn't want to hit the 3-4 rev limiter so for the first time I did some WOT 3-4 shifts. Did 2 one night, everything was fine.. Did one the next day and was ok.. did it again and it really didn't want to grab in fourth.. kinda slipped.
Well after that third didn't really want to grab to well.. fourth was almost a lost cause.
Now third can take about 15% throttle.. fourth can take about 5% before it starts to slip.
I was lucky I was able to drive the car home from the track (I didn't race it).
So I'm thinkign I will buy another stock tranny and just throw a transgo in it, change to a 3.23 gear to prevent 4'th usage and less WOT 3'rd usage. Then perhaps try and rebuild this one myself.

Re: Another 3-4 clutch pack takes a dump Bummer Magnus. You definitely need to build yourself a Super60. With that big stall converter, if you ever got it to hook, you'd be asking allot out of your stock low/rev planetary set. Not to mention the stock band, it's got to hold down second as well as 4th.
My truck trans shifts super and I will definitely use the same setup in my TA when the time comes.
