I currently have a 67 Camaro with a 327 motor in it with the stock 2 speed powerglide transmission. I was looking at changing out the transmission for something with more speeds, possibly a 4 speed automatic, and was wondering what transmission would fit. I would like to do this without significantly modifying anything. Also about how much am I looking at spending to do this?

The 200 4-speed auto tranny fits right in with min. problems although it isn't a direct bolt-in!

Check into it if you want.

Best place for info (besides here) is bowtie overdrives.
For a stock or near stock motor, a standard rebuilt or junkyard trans will be fine. For best MPG, keep the lockup torque convertor. There are various ways available to control it.

Lots of threads on this topic but a 2004R is the near direct bolt-in. I've done this swap in my 67 327 former Powerglide car. Overall length is the same as Powerglide as is rear spline so your driveshaft does not have to be altered in any way. With the correct bellhousing, it is also a direct bolt-on applation. Your transmission cooling will also work with just a slight bend here or there.

Changes: New crossmember. You can purchase or find in the junkyard a Turbo 400 crossmember and perform some slight modifications to it to make it work or you can purchase an aftermarket crossmember which will work. Try BowTie Overdrives. You will have to massage your hump slightly to allow the new crossmember to fit, but now much.
If you want to retain your original dipstick and housing, you'll have to trim some off the end so your underhood appearance remains the same.

Depending upon what rear gears you are running, and I'm assuming if your car has a powerglide and is stock, they will be on the tall side for the overdrive application and you will definetly want to gear down. I had to as the 2004R has a .67 final ratio and I was turning absurdly low rpm on the highway even at 65mph. Once the torque convertor locked-up, 55mph was not even acceptable as the engine would lug and almost shudder, rpm was so low.

Overall however, thes is an easy swap and I would recommend it.

Of course a turbo-350 (3 speed) is an easy swap as well, and gives improved performance due to the lower transmission gearing. A 200-4r has an even lower transmission gearing, as well as a .67 overdrive ratio on the other end. A 200-4r usually costs more than a turbo-350, but also allows you to run a faster, lower axle gear and still have better gas mileage. Best wishes.

Thanks for everyone's help. I'll look into this and let all of you guys know how it goes.

What's the difference between the 200r4 and the 700r4? A friend of mine said he's heard some not so good things about the 200. Would the 700 fit my 327 as well? I'm not too educated on transmissions so I really need your guys help here. I'm looking to replace my 2 speed powerglide in hopes of getting a little better acceleration and not have the engine rev up so high at highway cruising speed. Right now at 60 mph my car is at about 3000 rpms.

The 700 is longer than your glide, so the driveshaft needs to be cut. Otherwise it's a fairly similar and simple swap. The 200 has better gear spacing. Both have OD and lockup. Neither is terribly strong in stock form, but each is probably OK for a stock motor. There are more sturdy parts available in the aftermarket for the 200 than for the 700. I don't think you'd be disappointed with either.

A lot of those Buick GN boys have been beating on the 200-4r's for years and have made them pretty stout. I have a 200-4r in my 67' and wouldn't have anything else. Just make sure you get a 200-4r if you're considering a junkyard trans. and not a 200th. Those trans. were problematic.

[pdq67]

And the TH 200 is just a 3-speed, not a 4 like the TH 200-4R.

Would a 4L60E transmission out of a 2000 Chevy Blazer fit as well? There is someone locally selling one for a good price. Thanks again for everyone's help.
