Dark gray silt

[DorianL]

Greetz Gents,

I dumped my th350 for a 200-4R. I drove the car a few blocks. Heard a ticking sound coming from the converter. Sooo, I decided to replace the verter. In the meantime, I dropped the pan to find the there was some fine dark gray silt-like substance on the bottom of the pan. The pan had just been cleaned + new oil? What is this silt. I seem to recall a loss of power in second. Could this be a fried band ?

Should I put the new converter in there next week, or rebuild. The trans came from a 305 chevy and is now behind a mildly modified 400. 360HP, 450TQ

MTIA,

D.

Run a magnet thru it see if it picks it up that will tell you if its aluminum or steel ..

Forgot to mention

I tried that - magnet did not pick it up.

That's a bad thing, right?

Did you go thru the trans ?

Is the converter a rebuild or used ?

 

[DorianL]

I did not go thru the trans - the converter was a used one; I had it rinsed by a trans shop. When I put it on, the converter developed a ticking sound when hot. Sounded like running continuously a fingernail over the teeth of a comb. I decided to pull the converter. The 1-2 shift faded as you gave more gas !

Might be the converter.

If it was me i would go thru it before i put it back in the car.

If you do put it back with just the converter be sure to check line pressure to see where its at.

Many thanks Petesgn

The trans was working fine in the caprice it came out of. The source of the converter is unknown.

I'll try the new converter on there and if things don't work our immediately - it's a rebuild.

Cheers,

D.

BTW - by "go through"... that's a rebuild, right?

Thanks,

D.

The dark gray material is more than likely clutch material and may well be the source of your slippage. Mark
