Transmission Shrapnel

[1970Tex]

Hello I need some help from all the transmission guys out there to identify some metal chunks i found in the transmission pan. 1970 GMC with 350/TH350 transmission. I just bought this truck recently, and have not driven it yet, but it did make it into my shop under its own power (fwd and rev work). PO didn't drive it either as he spent a year or so resurrecting it from the dead. Being it winter up here in the 51st state, it wont see pavement for a few more months, and my inclination is to just drive it and see what happens. I would hate to spend a wad of money to get it rebuilt only to find out something puked in the torque converter. I have no plans to do any heavy towing or long trips, just drive it to the local car shows here in the summer. ID number on the pan is Y8S 21D (1968?) All pieces are magnetic, and the fluid didn't look that bad, bottom of the pan was sludgy and dirty, but not much metal grime.

Cheers!

Thank you raggedJim! I will have to phone a local transmission guy and have it rebuilt. I've had the opposite problem in the past, i thought i blew my TH400...paid for a rebuild, only to discover after, that it was actually the torque converter! Had this site been around 30 years ago, would have saved me a few bills!
