transmission sizes
 

Somebody a while ago posted some drawings of how to tell the difference between trannys. Wpould sombody be able to post this again so I can save it?
Thanks in advance

i have one tranny diagram saved on my hard drive i could mail to you, i fouind it on the net one day when i was using transmission keywords like th350 th400, identification, etc
i think coloradok5.com has one too

try searching with keywords on google.com
good luck

if its a 67-72 then if its a 69-72 and has 13 bolts pan, then its a th350, if its a 67 or 68 or is any other year with not 13 bolts pan thne its a th400, *if is original correct tranny

I think this is what you are looking for.

Thanks guys! The pictures that south pa sent me were exactly what I was looking for. A friend of mine gave me his tranny from his truck he was parting out and he told me it was a th-350. But now that I see the diagrams, I see that it's a th-400. The best part is it was rebuilt just a year ago!
