What type of transmission fluid does my A-727 take?
Dexron II or Dexron III I just need to top it off.
Thanks in advance.

Jim

 

My book say Dexron III

 

Just pull it apart and Jim Lane it. Then you could probably use H2O or whatever's handy.

If you don't know then no one does!

 

use the atf4+

 

ATF+4 or

I am pretty sure Dexron is a big no-no in chrysler trannies?

 

Interesting..
It says Dexron II right on the dipstick but after I had it rebuilt last time I wasn't sure if he said to use II or III but I know he said Do NOT use Ford ATF.

My trans started to slip a bit this morning but only until it warmed up, I think I am going to drop the pan and hope the magnet is clean and then replace the filter.
Thanks Jim

 

As far as I know, everything that originally called for Dexron II was ok for Dex III when it superceded II.

 

I am not aware of dex II being available anymore. Pretty sure Dex III replaced it. I have been using dex III in 2 different A518 trannies for several thousand miles. So far no issues.

The reason is that it is much cheaper fluid then ATF+3 or +4.

 

You need to use dex 3 i have built many 727 transmissions if it is factory the clutchs do not like plus 4 Also if you want a little bit of a harder shift and works better for towing you can use type f .

 

I looked at the couple receipts I had from the trans shop that rebuilt the trans in our 91 a few years ago. The trans shop used ATF +3.
Of course, all I find in the stores is +4 since I believe it superceded +3.

My original 91 manual specifies MOPAR plus fluid but states Dex II can be used if + fluid is not available.

 

type f

 

Wow! Jim you opened up a can of worms with that one. ...lets see...II, III, +3, +4, F, h2o...
I guess I will chime in with sawdust and banana peels...oldschool.

 

I like that idea! It's time for a flush so I'll try that sawdust ,banana thing

 

type f works well in the 727s trust me

 

i wanna run type f in my A-518 but i am trying to determine if running type f in the A-518 would be an y different then running it in the 727.
only differences i can see is the A-518 having the overdrive unit, other then that they are basically the same transmission.
