Im new, with Dynaflow problems, please help!

[Guest 56Super]

I am new to this site and I need help!

I have a 56 Buick Super that is leaking like Niagra Falls.

Its comming from the front, Im assuming from the front pump seal.

Im a member of RRR and some of the guys said that without looking at it that thats what it sounds like. I want to keep the original drivetrain if I can so any help would be appreciated.

Thanks

Craig

You should contact and join the local BCA ( Buick Club of America - BCA - Welcome ) chapter ion your area. Those guys will be able to help more than any other. There is likely someone they prefer to use professionally, or may be able to help you directly with the problem whatever it is.

Good luck!:cool:

Thanks for the quick response.

I am planning on joining the Buick club, was wondering on "free" advise as well.

Thanks

56Super, please check out the active Buick forums on this site. You might wish to post your questions in the Buick - Post War forum.

It could be the front pump cover o-ring as well. Before you take the trans out, pull off the inspection cover. You'll notice there will be several nuts (3 hold the flexplate to the converter, the rest seal the front pump cover). Make sure these are all torqued to about 25 ft./lbs. If any are loose, you'll get a gusher. Good luck! BTW, I'm pretty sure all Dynaflows leak somewhere; it's pretty much law, but it should be drops at a time, not puddles.

Thanks, I will check that.

drop the tranny and put a front pump seal in it...not a big deal at all...

Ive heared that doing the seal isnt bad but pulling it is, its a huge heavy pig...:eek:

Hi Craig-I'm currently restoring a 53 Buick and have removed engine and transmission for a rebuild as the car sat for 35 years.

My usual engine rebuilder has just finished the engine rebuild but finding someone locally to work on the transmission meant calling a number of local rebuilders none of which has current experience on Dynaflows. I did find a local rebuilder semi-retired who agreed to take in the transmission so long as I provided a Buick shop manual on rebuilding this year's transmission. Most rebuilders with Dynaflow experience are long retired as i found out. If you are in Western Ohio there is a guy there who claims to have current experience but I opted for a local rebuilder so that I can take it back if problems develop after getting it started.

These transmissions are not rocket science and I think anyone with auto trans. rebuild experience can rebuild a Dynaflow with help from the shop manual which has extensive info on the rebuild.

My transmission turned out to be a mess and I'm working on locating a better transmission.

I had my own 56 Buick trans. rebuilt 15-20 years ago by someone who had years of older transmission experience but he's now retired. It too had leaks but not as serious as yours.

Thanks for bringing back some fond memories. In the 70s, I had a 50 Buick with (weak?) dynaflow. One could stop at a red light, then as soon as it went green, floor the ol straight eight, and barely perceive the ol lumbedtruck in motion. About the time the light went yellow for the other lanes, it would really start locking the converter and I could barely beat the red light change as well as anger those behind me! but but the time one was making the turn in the left lane one would be flat flying. It was the strangest of acceeration versus time curves kind of like a cartoon.
