Can someone please help me ID what kind of auto transmission is on my 68 FB. The pan is square on two ends. The other two ends are at a 45 degree angles. Both of the angle ends are not the same. One is a longer angle than the other. Sorry for the poor description. I always thought I had a TH350 but I do not think this is the case. Polyglide? _______

Ok, forget the drawing in the last post. It did not come out as I had hoped.

Awesome site thanks. But I do not see my trans pan there. This is a 2 speed auto trans. No I am really mistified to what is really in this bird.I wish I could post a pic to show you.

Probably an ST-300. It's the BOP version of the Powerglide

Sorry for this question...What is a BOP? Would you happen to have a picture of the pan?

You will see the term BOP used quite often. It stands for Buick-Olds-Pontiac compatible. I hope this helps.

I think that is what I have an ST 300. So its safe to say this is not the original tranny then, correct?

Where can I get parts for this? I would like to replace the pan with a new one.

It could very well be original. That's what mine has. My guess is that they used this transmission for all auto-trans applications except the 400 cars, which received th-400s.

I believe the ST-300 was standard, though you could order a TH-350 (3 speed auto) with a 350 car (which mine has).

Do you know where I can get a new pan for it?

You have an ST-300 Tranny if it looks like this (which is what you describe)This is an ST-300 tranny off a 1968 350 2bbl combo i picked up for spare parts.You may want to try posting a parts wanted ad here and over on PY or PZ.Most guys can't give those trannies away.

Thats it. When I replace the gasket on the pan do I use just the gasket or should I also use some permatex, rtv sealent too? How would you do it?

I found a pan in great shape and it is sand blasted and primed. What should I paint it? Does anybody recommend any kind or type of paint for the trans pan? thanks again.
