Dynaflow question - thoughts on whether I should rebuild?

    Hi all,

    Still slooooowly picking away at my '59 LeSabre project. Decided to start looking at the twin turbine dynaflow. Last I drove the car was in 2002 or so and the trans seemed good. It had been parked from '94 until '99 when I got it running again after my grandfather passed. I moved it around here and there. Parked the car in the garage and didn't start disassembling until 2013. I noticed that the top of the trans had a date of late 1993 on it and a name. I know trans rebuilders do that when they rebuild them. Basically it appears it was gone through and only had about 5k miles on it before it sat. I remember draining some and it was clean. Fast forward to today. I pull the pan and the fluid looks brand new. The whole bottom of the pan has a thin layer of grey sludge that I think is clutch material, but no other debris. I drain the converter and the fluid is also incredibly clean. Pull it out and the seal looks perfect and no signs of leaks inside the bell housing. The torque ball was previously leaking a little.

    I have a rebuild kit and was planning on buying the shop manual and going through this thing, but am now thinking to just replace the seals and call it good. Thoughts?

    i wouldn't mess with it. the grey sludge could be from condensation. it wouldn't be spoiled just from sitting.

    I agree.
    If it ain't broke, don't fix it 'til it is.

    Cool. I think so too. Just wanted to make sure there is nothing I'm missing. The fluid was so clean and I know it has not been changed since the rebuild. At least I have all the clutches / o rings / etc to go with it. I'll just replace the front / rear seals, torque ball and gasket, & trans pan gasket, clean it up, and be done.
