ok I had I got the tremec working great! Thanks again on the help! I'm not sure what was wrong but I just took it back out replaced the bellhousing, pilot bushing, got the flywheel cut, and new slave cylinder (old one wasn't moving enough for my tastes, and yes I bled it hehe)

ok Now I was wondering if my motor mount might be too tall. The whole drive line shakes quite a bit over 30MPH. The shaking is not violent and does not feel like something is broke/misinstalled. It is most certainly speed related. I used the standard t-5 mount and have a x-member relocation kit from fortes parts. What could cause this u-joints? mounts? or is this normal for a tremec?

Sorry if I rambled I'm tired

Oh also is the spohn torque arm/x-member worth the money? $355

 

I had a nasty vibration (at 75 in 5th) after installing my TKO.
I'm using Moroso solid mounts on the motor and trans and poly on the torque arm.
The aluminum driveshaft completely cured my problem.
(bought a used 1LE from gmsports salvage for $100)
I was still running the stock driveshaft before that, but it had been balanced recently and still vibrated.
I think the output shaft of the Tremec trans being lower than the T5 just made it worse. (driveline angles being a little worse now)

Driveshaft is the usual culprit.But also..what bellhousing are you using?An aftermarket bell usually needs to be aligned to the crankshaft centerline otherwise it may cause a vibration.I went through this procedure when I installed the Lakewood bell on my motor.Took about 2 hours to dial in and setup..but no vibration at all.

 

From my experience that is not normal with the tranny. There is a bit more gear noise but I am sure that is due to the cut.

As far as the Spohn TA I give it a big thumbs up.

I am using the stock bellhousing with the adapter from fortes.

What do I do if it is the driveshaft? Where do I take it to be balanced?

Also are 4th gen driveshafts direct replacements?
