71 fury 727 tranny

[charles messler]

Hi all,
I been having problems with the tranny for 3 or 4 years now. It started when I was driving home from work. It felt like the warmer the tranny got the worse it slipped and the car wouldn’t drive. I got it home and adjusted the bands and it seemed to work better for awhile. For the past eight months when I put the car in reverse it’s making a cross between rasby and whine noise. Many times before I drive I have to put the car in neutral for a minute before driving or it will not move. I plan on having the tranny rebuilt but some people have told me to try change the filter. I’m scared of destroying the tranny since I see particles in the fluid now. Should I try to replace the filter?

If you are seeing a lot of particles in the fluid, it is time for a rebuild. If you flush you are removing the floating friction material. You flush it now and it will be worse.

Time for a through rebuild w/ master overhaul kit.

Where is the best place to get a complete rebuild kit from? Also I'm not sure if the car has its original tranny. Where and what numbers should I look for?

Pass side bell housing on the side will have the last 8 of the VIN stamped on a raised pad.

Then go Look on drivers side above pan rail. Will be numbers. Starts with 1 or 2 letters then seven digit number. Need those, the last numbers are dats, not needed.

Report back with numbers for decode.

Pull the pan and see how much trash is in the bottom, it will give you a good idea how bad it is. If the pan is clean change the filter and refill.

Make sure to drain the torque converter. Let’s get all of the old fluid out, not just half of it.

I wouldn’t waste time and money trying to change fluid and filter. The price of transmission fluid these days makes it an expensive gamble. At the first sign of trouble I take them out and have them rebuilt. I could rebuild them myself but, I have a guy that does them for $500-600 including new converter. I would probably pay twice that for peace of mind.
These cars we fool with are around 50 yrs old. The likelyhood of transmission failure in a car that old is pretty high.
Unless you know the complete history of the car you never know what gremlins are lurking about just waiting to spring a break down on you at the worst time.
I’m working on a ‘72 Polara now that the history of is unknown to me. I drove it for about a mile and it seemed to shift good but the engine was in bad need of rebuilding. I’m not taking any chances on the trans though. While the engine is at the machine shop the trans is getting rebuilt.
If you’re not careful, you can end up spending twice as much by trying to save a dollar or two on stuff like this as opposed to biting the bullet and doing it right. That’s my take on the situation!

Considering that the car has 139 thousand miles on it and without crawling underneath to check the numbers I'm guessing it's the original tranny I probably will have it rebuilt. I'll look for the numbers when it gets a little warmer here.

 

[charles messler]

Here are pictures of the numbers. The first two letters on the drivers side looks like DK

 

[70bigblockdodge]

Driver's side numbers start with PK
Looks like 3515344, confirm?
That number does not work.

 

[413]

Are the last 8 digits of your VIN. F1153857? Or something close?

The first letters are PK. Write PK and DK on a paper, cover the bottom third. Which one looks like your trans?

 

[charles messler]

Yes I forgot to mention it is the original transmission

 

[charles messler]

The numbers are stamped poorly. I found the number on my mopar.com but the 8 looks like a 3. I think the first two letters are DK.

 

[charles messler]

Has anybody used the kit from yearone?
