dynaflow advice

Hi Guys

I have 55 super with 322 nailhead and dynaflow the car had been sitting for some time and now that i've fixed the brakes etc and have her running the trans is leaking real bad ,real bad!!

The leaks seem to be coming from the front of the trans and the rear.

other than that the trans runs very smooth no sliping, or werid noises.

I went to two different trans shops and was quoted about the same 1000 to real seal up to 2500 to repair and re work the trans

I have never done any work on trans before .If i was going to replace the seals myself it looks like I would save a boat load of cash how hard to replace the seals on the beast, I figure to remove the trans and just reaplce to seal ,any info ,tips etc would help or do you guys think it best to have her rebuilt in a shop the car has 72,000 miles on her

Thanks for any help

We, too, had our Dynaflow rebuilt at 72,000 miles. Ours never leaked more than a few drops at a time. However, some of the converter blades had come apart.
When choosing a shop; Ask about their Dynaflow knowledge/experience. Dynaflow is like no other automatic.

I myself, do not have the tools, nor the facilities to attempt a transmission seal replacemnet. My knowledge is more in the vien of "book learning".

For me, I would leave it to a reputable shop that has a good track record with Dynaflows.

Thanks again bhambulldog . I bit the bullet and took her to a shop that has an "old guy who knows dynaflows" their words

One thing that is a problem is the trans cooler when it was disconnected one of the fitting just crumbled to bits so I'm on the look out for another one the shop wants to replace it with a modern type trans cooler, I;m not sure what to do I have checked the major on line Buick parts store and no of them list the cooler some have rebuild kits for the trans but no cooler

 

A modern type cooler (?). Do they mean piping the fluid to an air cooled finned cooler at the radiator?

 

yes sir it would be mounted up front by the radiator

 

Hmmm, That's a good idea.

 

Are you ready for some Dynaflow! You are aware that you need to slide the rear end of the beast back to disconnect the torque tube and driveshaft. This is a cumbersome job if not familiar with the procedure. Once you get the transmission out, the rear seal replacement is not too difficult. The front seal will need the torque converter removed, and this is a sensitive procedure. Basically you need to dissassemble the torque converter just to get to the front seal. The O-ring seal for the torque converter cover will need replacement also.

she back and running great:TU:

 

Hey nineteenfifty5,

What did you end up doing on your trans cooler?
I am trying to come up with a replacement for the cooler on my 53 Riv and am looking for info. Do you have any pics of your cooler set up?

Thanks, Rick
