ceejay Posted September 7, 2014 Share Posted September 7, 2014 Hi all,I need to get the dynaflow from my 58 Buick Century rebuilt.One company quoted $5000 and 3 weeks to do the trans and the torque converter.Does this sound about right for a full professional rebuild ?Any places that anyone can suggest I can ask that is competent to rebuild a Dynaflow ?

ceejay Posted September 7, 2014 Author Share Posted September 7, 2014 Yeah its a horrendous cost, restoring this car. We can not import classics into Sri Lanka so I did not have the option of importing a good car from USA. All my parts come from USA and all my chrome is going to the USA and coming back as well. I'll post a link to my restoration album soon 1 Link to comment Share on other sites More sharing options...

ceejay Posted September 7, 2014 Author Share Posted September 7, 2014 No Martin, I haven't thought of searching in Australia. Naturally I thought of USA because the cars were originally made there so I thought there should be a larger population of Dynaflow specialists in USA Link to comment Share on other sites More sharing options...
Pete Phillips Posted September 8, 2014 Share Posted September 8, 2014 I have a Dynaflow currently being rebuilt at a shop just north of Fort Worth, Texas that was recommended to me. It's a small shop in the suburb of Watauga, Texas, and the only two employees are a couple of older guys with gray hair who like old cars (a good sign!) and have done Dynaflows previously. I should have a report on this in another week or two when the transmission is done.

JohnD1956 Posted September 8, 2014 Share Posted September 8, 2014 Hi ceejay. First off, $5000 to rebuild a Dynaflow is too much. For your consideration, I am thinking $5000 USA Dollars. But I have heard of people spending up to 2000 USA dollars for that service. For 58 there are two different Dynaflows. The regular one has a "L" on the shift designator you see inside the car. PNDLR. The less common one has a "G" in that place, PNDGR. The less common one will probably cost more to rebuild as parts are more difficult to come by.MOST IMPORTANT, is for you to describe why you need to rebuild your transmission. Dynaflows are very durable transmissions. But they are not at all like other automatics of the time. There is a good chance yours does not need to be rebuilt. Can you describe what you feel are it's problems? Link to comment Share on other sites More sharing options...
Restorer32 Posted September 8, 2014 Share Posted September 8, 2014 Check with FATSCO in New Jersey. They have done several Buick trannys for us including a '53 Buick, a '58 Cadillac, a '59 Cadillac and several others. Last one we had done was less than $4K. Must be a major pain restoring a car in Serendip! Link to comment Share on other sites More sharing options...

The unit is really easy to rebuild. And of course you may only need a seal up kit, which is reasonable in price. If it were for me, I would rebuild it myself. Hardest part is the rear end being slid back to disconnect from torque ball on transmission.MOST IMPORTANT, is for you to describe why you need to rebuild your transmission. Dynaflows are very durable transmissions. But they are not at all like other automatics of the time. There is a good chance yours does not need to be rebuilt. Can you describe what you feel are it's problems?The other dynaflow is known as FLIGHT PITCH dynaflow and it's very hard to find parts for. It has PRNDG for the shift indicator. Standard equipment on 58 roadmasters and limiteds. Optional on Supers, Centurys, and Specials.The dynaflow you have has parts available and are reasonable. If it were me I would rebuild it myself.

ceejay Posted September 11, 2014 Author Share Posted September 11, 2014 Thanks everyone for your comments.The car I bought to restore, had not run for 15 years or more. The car was parked in a semi open garage for this time where it was exposed to lots of moisture.The outside of the transmission is a little rusty. I'm sure after 15 years of sitting in one place, that it needs a full service with all new gaskets and seals ??I could import the full rebuilt kit and let the best auto transmission shop in the country (Sri Lanka) service it. However, they have never ever seen a Dynaflow before so they will not know how and what to check and how to adjust the various things inside.Looking at the factory workshop manual for the Dynaflow, there are a LOT of complicated procedures to go through, to service and adjust one correctly.This is why I am thinking about sending my trans to USA to a professional and having it done.

JohnD1956 Posted September 11, 2014 Share Posted September 11, 2014 Interesting. I might think the outside rusted cause it was cleaned. If it was, chances are it was cleaned when it was serviced or rebuilt. An original Dynaflow that was never out of a 50's Buick is almost certain to be covered with dirt and grime. You may be right about dried up seals, but that would most likely just be external seals. Is it still holding trans fluid? If so I would just replace the torque ball retainer seal and the front transmission seal. Both of which should not cost you the thousands for shipping and rebuilding, and potentially losing, that transmission. Any chance of getting the engine to run so you can test the trans before deciding? Link to comment Share on other sites More sharing options...
critterpainter Posted September 12, 2014 Share Posted September 12, 2014 If it is just a Dynaflow, get an external reseal kit from a supplier along with the dynaflow repair manual and take it to your local shop. Should cost thousands less than shipping that heavy beast to the states and back! Link to comment Share on other sites More sharing options...
Guest 54fins Posted September 14, 2014 Share Posted September 14, 2014 I tend to agree that it either doesn't need a rebuild or a fairly minor fresh up. They are not very happy getting towed and that's the main way to ruin them. When they are low on fluid, they won't go and they really are not quick enough to get ruined by a teen messing with the car. The 5K is absolutely absurd, start with an oil change. The rear seal is a likely leaker. Then your old motor mounts will mess with the shift linkage. After all that, if you still have issues then I would first pull it apart and inspect it. If there are obvious problems like metal shavings and broken parts then drop back by Link to comment Share on other sites More sharing options...
BillMadden Posted October 1, 2014 Share Posted October 1, 2014 "they won't go and they really are not quick enough to get ruined by a teen messing with the car." I would like to beg your pardon..... If you have a buddy who has a '53 Olds 98 Holiday you get really tired of not being able to keep up. So, put it in Neutral, rev it up tight, whip the shifter to Park. Darn, it only works a few times and then guess what.... And that's the end of my story of my first '53 Buick Super convertible. Link to comment Share on other sites More sharing options...
Guest martylum Posted October 2, 2014 Share Posted October 2, 2014 Hi Ceejay-I'm restoring a 53 Buick Roadmaster and had quite a problem with the original transmission. When we removed the transmission oil pan the fluid inside was black with powdered aluminum particles on the floor of the pan. The transmission rebuilder advised me to find another transmission as the oil had deteriorated due to poor maintenance causing so much wear on the moving parts they were trash.I ended up buying a good used transmission from a rebuilder in Ohio and having the rebuilder do the rebuild job.So before you spend money shipping your unit anywhere you might have a good mechanic in your area inspect the parts you have.We bought a used transmission from a Buick club member who stated the fluid in his unit's pan was fine. When we received it was also black oil and the parts useless.We are just getting the engine running and driveable so no report on the tranny yet but it does go into gear.Martin Lum53 Buick 70 series Link to comment Share on other sites More sharing options...

That was nearly four years ago and the car is no longer with me, so I don't have the receipt.

jackofalltrades70 Posted May 15, 2018 Share Posted May 15, 2018 Get the engine running. Drop the pan and change the filter and fill with fresh fluid. Then test it to see if it works. If it works and leaks, you can repair the leaks. If doesnt work, get a shop manual and follow the guide for troubleshooting. I used this guy for my 56 tranny.

Misterbuickguy Posted August 25, 2018 Share Posted August 25, 2018 Just stumbled upon a shop in California that specializes in rebuilding Dynaflows and other early transmissions. I just have a feeling that he is expensive. (Just my gut feeling). Since Dynaflow rebuilders are getting rare, I'm posting the name of the shop and website.

Bloo Posted June 4, 2019 Share Posted June 4, 2019 You definitely want to take that to someone who really knows Dynaflows. As I understand it, on some Dynaflows the band can unhook and the link fall out. It might be a fairly easy fix. Link to comment Share on other sites More sharing options...

Dukepol Posted July 3, 2019 Share Posted July 3, 2019 (edited) I have a Dynaflow transmission that has been stored in my dads shop for years.

I sold the convertible and a parts car years ago. I only found transmission this weekend tucked away in the corner. I am looking to sell it. What Is the fair value price of one of these.
