I love the 36 sport coupes, but this paint scheme looks awkward to me. No eye candy to me....

Dear all, I continued a threat in the post war Buick section of the forum about Dynaflow problems. Link below. Hope to get more traction in this general technical section of the forum. My 49 Riviera has two problems, when I shut the engine off it spills out transmission fluid through the filler neck, and when I shift into reverse instead of moving it starts shaking and rattling. Very scary. A more detailed description in the post war post. Thanks for every idea and hint. best, Hans https://forums.aaca.org/topic/388569-dynaflow-blow-back-through-fill-tube-in-reverse-causes-and-fixes/?do=getNewComment

Opened the cap for the reverse band. Obviously the transmission pan is full. I understand that is not right. There seems to be a drain plug where the red arrow is. No idea what for.

I never noticed bubbles on the dipstick. Thank you, appreciate your help!

EmTee, thank you, I have no idea, if the transmission has been rebuilt in the past. Overall it seems to be a low mileage car. To measure the line pressure is for sure something that would be good to accomplish, but honestly where I live I have no clue where to go, so I need to do it myself. Before I walk that way I'd like to understand as much as possible about the problem. Ideally somebody says "hey, these symptoms point to this or that desease." Unfortunately I am not such a technical mastermind, which frustrates me slightly. I don't think there is any foaming, the fluid is just pressed out over a few seconds. Only the area underneath the dipstick whole is wet.

I do have a very similar problem on my 49 Riv. When it is cold, it is pretty normal. All gears work as expected. When it is hot, I can go forward in D and L as I wish, but when I go into reverse, it gets scary. It shifts into reverse, but as soon as I accelerate only a little the whole car is shaking and rumbling like crazy. Very difficult to locate grom where it origins. I need to shift immediately back into other gears and then it stops this shaking and behaves nicely again. Reverse gear again, shaking restarts after I push the gas pedal a bit. When it is hot and I stop the engine ca. 3-400 ml transmission fluid comes out of the filling tube. I let it cool down for 5 min and I can normally drive backwards once or twice and then it rumbles again. I stop the engine and another load of transmission fluid comes out. Length of the dipstick seems to be right, about 17 inches. When I use less transmission fluid (level at lower end of the dipstick) I have considerably worse acceleration, so I like it to be full. The fluid volume to go from minimum to maximum level seems only to be 500 ml. I only refill when warmed up. Motor mounts good, transmission mounts, thrust pad new. I never really drove the car before the exchange.... What I realized yesterday evening after removing the huge floor pan cover to gain access to the transmission is, that the shift rod at the rear end where it meets the transmission has some slippage due to the fact, that there are no washers to keep it tight. Maybe this potential movement causes some trouble. But with regard to the normal shifting when cold and stumbling in reverse when hot this cannot be the problem, I believe. Same for the spitting! What I have read here a couple of times is the addition of STP transmission additive to make the Dexron III more viscous to prevent the torque converter to empty itself into the transmission pan after (!) standing for a while. Mine seems to do that while hot and shutting off the engine. So can the viscosity be the real problem here? By the way I had no leaks at all before, torque ball even nice and tight. I will try the STP for sure. I just don't understand the problems. What is the exact function of the breather cap with the short pipe. If this is clocked what is the consequence of that? This is above my capabilities up to now. A little frustrating. ... Next is putting the rear axle on stands to see if the differential causes the shaking.... Thanks for any idea what I could try. Maybe the above makes sense to somebody.

Still have this problem. I checked the linkage and I flushed even the Dynaflow. When I go into reverse in the first moment nothing happens. When I give a liitle gas it starts rumbling and shaking. So heavily tbat i need to push back into L or D. Then I drove back, arrived at my garage and the dynaflow spit some fluid out, ca. half a liter. After shutting off the engine and waiting for 5 min, the reverse was back. I drove 2 m back and forth a few times and then it lost again fluid and I had no forward or reverse gear anymore. ... Does anyone have an idea?

Great find. I contacted the guy!

I can only repeat myself, the straight eight with manual transmission is just a wonderful combination. Of my 5 Buicks I would sell my 47 sedanet at last. Drives nearly like a modern car in city traffic. Juicy enough with excellent brakes and an unbelievable amount of style....

Hard to say if the price is right. Surprised about the engine bay and the undercarriage. For this kind of money I'd expect better. The blue doesnt look right to me either. Or my cell phone doesn't display it right at 4.30 am.....

Dear all, I need some advice. I try to revive my 1981 Firebird V6. I know this is for most the least desirable version, but - I love it. When it was still running I had excellent gas mileage and I used it as a daily driver for a few years. Three years back it was flooded, fully, for a few days. We cleaned and dried it, as best as we could. I think the engine is safeable, but I want to get rid of the stock carburetor and intake manifold as the car is really heavily underpowered. Many years back I had bought an Edelbrock intake and the 1402 carb for my V6. Accidentally found both. This cannot be used with the computer unit that these cars have to reduce emissions, so the computer needs to go. No idea how much better this setup might be , but I am a little hesitant to spend 4000 Euros for a 403 Olds that was offered to me. What else do I need for this project? A distributor I guess that does not depend on the computer? Can mine be adapted? Where can i find one? What else? I am still in dismantling mode. Any general advice? I take everything! 😄 Thank you! Best, Hans

Looks like a spaceship just landed on earth. Unbelievable thing. I wonder how it was to be young in that time period with such extraordinary design around you. Did it influence your thinking, your way of life, your idea about the future? This car might be overpriced by 5 grand or so, but when have you seen one like that the last time? Rarity costs. I adore it. I cannot buy them all.

Are you referring to the '49 Roadmaster sedanets which would be the adequate car to compare the 48/49 Cadillac fastbacks with, right? I haven't seen any of these available for some time and not in the 'high teens'. If you know where I can find one, please let me know!!! I w a n t one! 😊

This morning I took my '47 Super Sedanet and went to the mandatory car inspection here in Germany for the very first time after the import. After all the work and effort and passion to make it roadworthy this is the moment of truth. No hiding, no BS - 6 people stood around and underneath the car, inspected it literally from every possible angle. The result - it passed without a single remark, either the roadworthy test and the classic car check. It cannot be any better. What a relief! And what a beautiful piece of art.

Hi guys, need to share a few pictures of my 47 Super Sedanet. Polished, roadworthy and real eye candy. This design is so outstanding. Just watched again the Buick Y-job on the Jay Leno garage show on youtube and recognize so many styling cues on my 47....
