TH400 Noise Under Full Load From a Stop (Video Inside) Hey fellas.
So I finally got around to playing with the car a little. It's a 73 Camaro, 350/TH400. I just added some lucas to the trans, took it for a drive, and recorded this video. If I floor it from a stop, this is the noise I get. It makes this noise and chuggs along like I'm at 1/8 throttle, until it gets higher in the RPMs. If I start off gentle on the gas, let it get to about 2500 RPM's, and THEN punch it, it's totally fine - which you will hear in the video. It only does this if I mash the gas. If I drive like a civil human being, it's fine (aside from a very faint squeak/whistle in 1st and 2nd).
As you'll see, I punch it from a stop in 1st gear, you'll hear the noise as I let off, gently get back on the gas to bring the RPMs up higher, and then punch it, shifting it into 2nd. (hurst shifter, not a manual valve body).
Any ideas guys? I did a fluid and filter change 6 months ago, and I only take the car out on the weekends for short rides. I do beat it up quite a bit, though.
