Lost close to 100rwhp through drivetrain: What could've caused it? Can a rediculously overfilled tranny cause such a breakdown in hydraulics to cause that much
drag? Or was my Torque Converter bad?
My engine threw a rod on the highway so I replaced it with a new shortblock. I put back in my
Vig3200, and went for a drive. I had a strange hollow-rubbing noise coming from the tranny
area that could only be heard from inside the car.
I went to the dyno and only pulled 283rwhp, down from 321rwhp, pre- cam!!
Now, I messed up and overfilled the tranny. I mean absolutely overfilled it. I assumed I had lost
just that much fluid. When the Vig was being pulled fluid was shooting out the tail when the
driveshaft was taken out. <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" /> As well as anytime the tranny was moved.
So could it be the fluid causing the loss, or a bad TC. Now that my stocker is back in, I'm
back in the high 3XX rwhp.
Any theories?

I think either I had WAAAAAYAYYYYY too much fluid or the torque converter is bad. I'm just trying to get some opinions on wheter it could've been the fluid.
I really don't want to spend anymore money on another TC

Re: Lost close to 100rwhp through drivetrain: What could've caused it? what does the torque curve look like on the dyno? does it just go up a little then flat line across? if so I would say your slipping.

Re: Lost close to 100rwhp through drivetrain: What could've caused it? From what I understand the 4L60-E cannot be overfilled as long as the vent tube isn't kinked/clogged. The fluid will just heat up/expand and overfill will expand out the vent tube.
On my car the vent tube is clipped to the torque arm.
Happy driving,
