Are all 1:1 72 transmissions the same, I found a 10-18-002 on ebay, thought mine is a 10-18-001 but it has a couple coats of paint on the id tag so not 100% sure of what mine is now. would this work in place of mine or is there a difference in the two.
thanks

yes it is the same, just labeled differently because of pump rotation

if searching for newer BW transmissions always search for the 10 dash numbers, the ASi or 2 models are older and could be from the 60's, dont pay much more than 200.00 for a core that is in someones garage....its there for a reason. it seems when i pay 50 bucks for a core, they are in better condition than the ones i pay 300.00 for. IMVHO, dollar for dollar they are the workhorse of transmissions

I ended up buying it, got it for $650, hope I dont get screwed looks brand new and you can see that the flange has never been bolted up. So hopefully it wasnt just dressed up, the dipstick and everything I could see through there looked shiny and new. Would you be able to tell me what damper plate I would need or is that something I would need to remove the old one to find out?

pull it first in case they use heavier one on the BBC's, if the trans is new your not getting hurt to bad

Weathers getting nice time to install, I have been trying to find the torque specs for the damper plate bolts but have not yet found it if anyone knows please let me know, also is there a specific torque process.

Chris,
If a torque isn't published by the engine manufacturer, then typically the bolt/nut is a "off the shelf" so follow the SAE specs for the given grade and size. The Machinists Handbook has them listed as well as "Pocket Ref" by Thomas Glover. Next time you're at the hardware, look for the Pocket Ref - It's a small black book with LOTS of info in it. It comes in handy! I have one at work and one at home.
In the mean time, http://raskcycle.com/techtip/webdoc14.html - here's the SAE standard specs
By "torque process" do you mean a sequence of torquing down the bolts? Not really but you can tighten just like you would the lug nuts on a wheel - random opposing.

and remember install the trans into the bellhousing and go thru the starter hole and tighten the bolts, this will center the damper plate for you, yhen go to the alignment thread and follow word for word
