Is there any visual difference between a TH350 and a powerglide? I have the trans out of the car (which I've never driven) and the only numbers I can find are on the pan (Y6R 06N). Can anyone help me id this thing?

Hey, guys, does the P/G have powerglide cast into the case in big letters or am I thinking of another auto trans with its name cast on it?? pdq67

pdq67 I think the trans has a big 12 T stamped on the side of the casing. Does this help at all?

This may seem a bit elementary but...Powerglides are the only GM trans that I'm aware of that has only 2 forward gears. How many clicks do you have when you run it through the gear selections. Or easier still if you have a console with a shift plate you should see: P R N D L for a Powerglide assuming it wasn't replaced when/if they changed to a 3 or 4 speed automatic.

PowerGlide tranny's do have PowerGlide stamped into the housing (on the drivers side if my memory is correct). Also they are only 2 as described above a low and drive. The "Y" in your code I beleive means its a TH-350 made in Toledo Ohio. What year is your car and is the transmission original?

My car is a 68 coupe and I'm not sure if the trans is original. When I bought the car it came with a B&M floor shifter but still has the steering column shifter without the gear indicator. I think it orginally came with a 327.

Yeah, it IS hard to explain. I've got a service manual that shows the various pan gaskets which makes it pretty easy to identify your trans. Unfortunately, I have no way to input the illustration. That's why I suggested running it through the gears and counting the detents. But hey, if in fact "POWERGLIDE" is emblazoned on the case itself, that might be a pretty good clue...yuh think?
