I got the Monte on the road for the first time since the new 496 big block, full manual TH400 trans, and 8.5 rear end swap the other day and ran into an issue. When accelerating normal everything is fine but when I shift into 2nd it chirps the tires like normal but then it seems like it stops accelerating, almost slipping but no jerkiness. Engine rpm increases like it should but the car just revs and doesn't move. I only took it to about 2500 rpm because I still had the break in valve springs in. I drove it for about 1/4 mile like this before returning home to check things out. I checked the trans fluid and it showed way overfilled. I thought that was odd because it at most has 10-11 qts in it, odd for a deep pan TH400. I pulled it into the garage and I came out the next morning to find a massive puddle of ATF under the car. Sure enough its leaking from the dip stick hole.
Well today I drained some fluid out until it was around full, swapped in the valve springs and started it up. After letting it warm up I put it in gear. With it in 1st gear, foot on the break, I revved it up. It spun the tires for half a second then stopped, just continued to rev. I did this 2 more times before shutting it down. Checked fluid, its just barely over the full line.
So my question is does this sound like a slipping converter or an overfilled problem? Transmission goes into 2nd perfectly so I cant see why it would be the actual trans. I bought a used B&M 3000 stall converter a year ago at a swap meet. I know it was stupid but I was working part time and the price was great. I planned on buying a quality converter when I do the roller swap this coming winter and was just hoping that this one would get me by for one summer. Fluid still looks red/pink and there isnt any funny smells or noises. Any ideas? Help a fellow Gbodyman out lol!
