Harrell Camaro

[Rat_Pack]

On a TH400 the number is stamped just above the pan and between the two drivers side pan bolts in between two small reinforcing ribs . It is very hard to see if the exhaust is still there. I had to use a light and a mirror to read mine as the lh headpipe runs parallel with it. Powerglides and TH350 transmissions usually have it stamped on the bellhousing portion next to the block on the drivers side, check those places just to see if it is stamped there by mistake. If no number can be found then it may be a replacement trans.....................RatPack................. ...
