2018年10月2日 · 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 …

2015年3月14日 · 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 ...

2018年10月6日 · 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.

2012年10月26日 · 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.

2025年1月10日 · 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”.

2014年9月7日 · 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.

2012年5月16日 · 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.

2015年5月10日 · The Mercon you are seeing is probably MerconV and like all the newest fluids is lower viscosity and may be too thin when hot to maintain adequate pump pressures in a dynaflow that may be getting weak. On the other hand the dynaflow has all the same materials inside that the modern transmissions have so any fluid would be compatible. Willie

2023年11月17日 · If a 56 Dynaflow is to be installed in a 55 Buick you should know the following. The overall length of the 56 transmission is 1 inch longer than the 55 small series transmission, but have the same overall length as the 55 big series transmission.
