50 buick S8 Dynaflow ????

I'm looking at a 1950 buick with a 320 straight 8, and a 2 speed Dynaflow transmission. How good are these early Dynaflows ? were they good/ or OMG don't even think about it ?
I'm not thinking of building a quick ride/ just a highwy cruiser 60-70mph.

 

They are pretty durable if treated reasonably well. A bit sluggish on acceleration. The torque tube joint is prone to leak with age but there are seal kits for that. Just bear in mind this is a 60 years + tranny................

Rusty,

Go to the Album Section of my Profile Page and check-out my '53 Special pix. A 263 Straight 8 with Dynaflow...whisper quite, never a problem with the tranny. You just have to respect it and not "dog" it, it cruised on the Hwy. at 60-70 with no problems.

Again, they're not hot rods. If they're set-up right, treated right, they are strong and will last a long time. And you can cruise for many, many miles...trouble-free.

I have one sitting on my trailer that took out and tranny with tube. Ran great

 

WATCH out for rear seal leak in the dynaflow. Lost a rearend when transmission fluid diluted the rearend gear oil. Other than that the car would pull stumps.

 

I treated mine bad...broke several. Really nice when they're working though.

 

here is one I used to have with the 320 and dynaflow 2 speed. We put a camaro rear end cause I could not find a rear end shop to rebuild mine. The camaro rear end was poorly done up though. I only drove this car around the neighborhood. Never father than a mile from home.

I prefer to manually shift mine. The car accellerates better and the tranny shifts nicely.

I have had dozens and have yet to discover a problem.
