Oct 2, 2018 · Hello I have a 49 Super with Dynaflow, Mine was leaking at the torque converter,had been apart sometime in the past,replaced all of the bolts with nylon inserted lock type.Found a number of the original bolts were cracked along the slots on them , allowing them to back off.Dynaflow apparently leaked when fairly new,In the program service bulletins …

Mar 14, 2015 · Dynaflow is really a simple transmission where the torque converter does nearly all the work. There are no gear changes as with the Hydramatic. In 1953 they simplified the torque converter and improved the acceleration from a standstill by using one pump, one stator and two turbines (this was called a Twin Turbine Dynaflow) coupled together ...

Oct 6, 2018 · The Dynaflow is a curiously cool piece of engineering. Of the 5000 miles I have put on the Dynaflow in my 60, it has been nothing short of smooth. As far as the line take off...it is sufficient for my tastes. I have yet to drop it in L for any reason as I have no reason.

Oct 26, 2012 · Joes opinion is a Dynaflow is a fairly simple and durable unit. I have to admit, if all a unit needed was bands and clutches and seals, and the disassembly stayed at the major subassembly level and there were no other "nuance" failures, my skills would probably be sufficient to disassemble, replace the typical worn parts, and reassemble.

Sep 7, 2014 · 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.

Jan 10, 2025 · On this site, look for 1950 Buick Dynaflow Transmission Removal. There are two or three very detailed explanations on this job even though yours is a little newer. They are hard to pull up but they are there . You should also google “JimHughes@Jims dynaflow service”.

May 16, 2012 · 55 Special: short dynaflow, Code stamped on reaction flange is O (letter) 171, casting # on flange is 1166129 2, date code 4-55. Cast iron bell hsg 1163913-3. add this one to your database research. The assembly pn is 1166140 which uses a bushing in the reaction shaft, this pn is unique to the 55 but the casting # may or may not be.

Oct 8, 2012 · The 55 Special dynaflow that I drove in high school and later routinely beat 55 Specials with 3-speeds. Every time the the 3-speed shifted I gained a fender length. The dynaflow was started in Low and held there until 60-65mph or whenever the points and/or valves floated.

Feb 21, 2018 · Certainly. I think the real question though is how long will it stay leak free. My understanding of the Dynaflow is fluid pressures are created to make the transmission provide power. There are two pumps working like mad to make us go. These high pressures(200 psi) will eventually find ways around seals and gaskets.
