Help with TB & Input shafts Please

[Since 1964]

Here's the problem....I start car and hear chirping and squeling and grinding UNTIL....I push the clutch in and NO NOISE....So I called the dealer thinking it's a through out bearing and HE say's.....Probably NOT, sounds to him like an inputshaft bearing. YIKES!!!!

I thought it took more than a 2.93 and a tune to eat an inputshaft...WTF?

Can anyone tell me what to expect????

If so, and I need the repairs done to the trans...where do I get an input shaft to substitute for a better one. I'm sure the dealer will let me switch parts, I just don't know where to go for it.

Liberty Gear in Michigan makes a 26 spline input shaft for our cars. I just upgraded my clucth, PP, input shaft, etc. and used their shaft. I'm still breaking the clutch in at the moment.

What's with all the clutch/TOB problems lately? My TOB just started howling like a banchee, too. Time for input shaft/clutch/TOB/flywheel I guess.

"Liberty" is on BACK ORDER!!!!!!!! I'm gonna find out tomorrow if they can get one in 2 weeks........WTF

So would I be a rat if I demoded and got a new trans & clutch?????????

Don't answer that, I already know.

So who's the wizzard around here that knows these transmisions.

Where would I go?

Sounds more like a broken TOB retainer sleeve to me...

Sounds like a TOB and maybe the input shaft bearing retainer (sleeve).

Turned out to be...some part of the case that's craked? Update...the( front case housing cracked )Somewhere anyway they are putting in my Liberty Input Shaft, a new CenterForce Clutch...I didn't need one...but since they were there I took advantage of it since the stock disc won't fit the 26 spline shaft and besides, it will perform better overall. BOTTOM LINE....TRANS IS UPGRADED....They are also installing the COOLANT MOD...so now my tune can be adjusted with better timing.

SO....do I port the Blower????? Take advantage of the new deal over the winter? I wonder.

Go for it!!!!

Yes, the $395 deal is a steal! Trust me Dennis, a port job does wonders for these cars :burnout:

Hey, I just upgraded to a Spec 3i clutch, can I get a beefier input shaft that will go w/this clutch, or do I gotta get a clutch that fits the input shaft,too?

Apten + 2lb Lower = Flying :headbang:

Will I need a bigger heat exchanger??? I just don't want to need one of those over the potential of halfshafts....although...that guy that ran the 11.18 at the last MSC said he only bought the bars...imagine that...is it that simple?

Did you guys see that last race from SonicBlue.... the guy with the coolest picture of all running down the highway...he's totaly stock not even MJ's brace....he launches @ 6000.....crazy fucker...I just want to be able to stop at the porting, and I don't want to over spin this bizoch.

Ported with a 2.93 gets low 11's??? I don't know. The chicken in me just isn't dead yet. I need to know the new rules will allow it.

No.

You should have gotten the 26 spline input shaft, which is the only upgrade to the input shaft I am aware of at the moment, then gotten a clutch to match.
All is not lost though. You can just replace the clutch DISC with the equivalent 26 spline version when you install the new input shaft.
Liberty Gears has the 26 spline input shaft for about $250.
I am guessing that Spec has an 11 inch, 26 spline disc that you can use.

Dan, at what HP will I need the 26 spline input shaft?

 

[Dana]

That is a good question.
I haven't kept track of the power the guys have had that have bent or broken them.
I would guess if you are planning on porting the blower or replacing it with another larger one, that would be the time to do the input shaft.
Around 500 HP, I guess.
These transmissions aren't rated above 440HP, if I remember what I read correctly.
I did mine last winter when I did the clutch, but I was already at 525/585 by then, but it looked fine when I pulled it out.

I only got about ten passes on 2 different ocassions and my trans cracked.
See my mods...it happens once you go past CAI / Catback / dyno tuned, the 2.93 did it....I'm NOT shocked.........the car is an animal with a 2.93 much less 2.80 etc.

 

[Flyn]

Even stock you can break the trans. My output shaft went instead of the input shaft. The beefier parts help but there're still no guarantees. My TOB is getting worse again. It's squealing more and more. I'm short on cash so I'm trying to hold off bringing it in until I have the spare change for a clutch/flywheel if it's necessary.

I'm surprised F8tlbite? (SonicBlue at MSC 2.0) doesn't have a brace on his car, but I think he should. If you're concerned with parts breakage, I suggest the half-shafts over the heat exchanger. I also agree with Dan that the 26 spline input shaft would have been good to do when you were doing the clutch.

His car runs hard (I know firsthand, he knocked me out of the heads-up class). His 60' ft. against me was a low 1.7 (BFG DRs). I'm pretty sure in addition to the 2.93 upper and ported blower he also has a lower pulley. I never did find out how big the lower was. There was conflicting info, but it was at least a 2lb lower I inagine. He trapped 124 mph when I ran him. I'm very impressed with his car. :hail:

He told me a 2.80 pulley, ported blower...3 times to get it right by the way.....and a 1lb lower that he tried others 4ld etc., but the car did best with just a 1lb lower, go figure. I think he said he had MJ's brace too.
