Powerglides. Hey, they ain't so bad after all.

So in the new 69 resides a 35/250 with a Powerglide. Works and shifts as intended behind the 350. Just does it's job.

I never thought I'd like a 2 speed, had mental designs on a 3 speed and maybe a OD,  but I have to say it's a fine transmission for a cruiser with a 2.93.

Exceeds what I would have thought, smooth, great shift and a quick down into low guaranteed when you floor it. A easy build if needed. The only downside is that whine in park, but it gets forgotten quickly enough.

 

Why would you need anything else...

Oh, and my money is on it being 2.73 gears vs the 2.93 you mentioned.

I lost ownership of it as soon as she saw it. Says she wants to do a wedding car business with it. Randy will cringe at all the scotch tape on that black...

And yes, yes, 2.73's! I never go that low, so i'm not too familiar with these gears. But I'll learn.

 

It's been a while since I've had a CP that could do 80 mph on the highway. Nice.

Powerglides Rock!   best part about them is you can pull one that hasn't run for 30 years out of a swamp, and just start driving it and it will be totally fine.

 Ouch, I hope you use masking tape and not Scotch tape!

I just can't do Powerglides, no matter how hard I try. Yes, I know once you're on the highway it doesn't matter but I've been this way since I was 16. My first 65 Canso SD was a 193/Powerglide and it became a 283/TH350 very quickly. 

You KNOW this convert would be cool as a bench seat 4 speed Mark...

 Seen it too many times, crazy but true.

And they only consume 18-hp to drive. A standard non-clutching fan on the water pump uses 7-hp. A Chrysler 727 Torqueflite, about 46-hp.

My Chevelle Owner's Manual talks about how to bump-start a car with a Powerglide. First of all, what? Second of all, you need to push the car to 30 mph.

Driving a Powerglide on the street, a modern CVT acts the same in traffic except it is way weaker than any Powerglide.

The transmission was rebuilt in 2012 (76,800 miles) by a former long time GM mechanic in Niagara Falls.

The same mechanic had been servicing that car since he was 14 years old.

You can run this car up and down the highway without even thinking about it.

It's set up to be a very civilized cruiser.

When it looks that good, it doesn't have to be any more than that.

By the way, lots of chrome and stainless to stick stuff on to biggrin

 They still have that in 1967? I thought that quit around 1965 or 1966. Wasn't that when the powerglide didn't have a rear pump in it anymore?

 I would say you are right, Carl. They probably overlooked updating the section in the Owner's Manual for '67.

my first experience in decades with a powerglide (actually a BOP ST300 which is pretty much the same) is in my new 69 Firebird ragtop. It has the base 175 horse 1 bbl OHC 250 and the two speed automatic on the column. The whine reminds me of the engine sound in an 80's Grand National, without the go power of course. The car has the standard 3.23 axle that came with this powertrain and it is fine around town. Biggest drawback though is that with the 3.23 you don't have a usable downshift at highway speeds. The TH350 trans was only $20 more, and this car is pretty highly optioned so surprising that the original owner or dealer didn't specify the 3 speed automatic instead. Perhaps it was because the TH350 was brand new in 69 and anyone who had owned cars in the 50's up to the mid 60's knew that the word "NEW" and "automatic transmission" in the same sentence was often BAD news! The TH350 turned out to be a great trans from day one but no one knew that at that time.

I've always been curious... what is the cause of the whine and why do PGs have it while other automatics don't?
