transmission fluid

[SlowJoe]

i went to autozone and advanced today and they both said that the dexron 3 was called dexron 4 now. so i did not get any until i find out something about this. so has anyone heard anything about this?

As long as you do not buy Dexron 5 you should be fine

go to O'reilly in Ft Payne, see Joe (), or Rainsville and see Brandon, and get multipurpose atf fluid. Help drive my stock prices up by not shopping at the A-places!!

all these auto parts stores need to update there computers. went to all three and i am still short a rear trans seal. all they are showing is a WCT5,T-45 threw 2003. mine is a 2002 with a 3650. ford put the 3650 in halfway in 2001. Are the 3650 and t-45 the same seal or what. i want to get this running tomorrow and dont want to mess the seal up trying to get it out if they are not the same.

Autozone did show the 3650 but the seal was N/A.

seal should be a national part number 710431, but national's online catalog isn't very clear on that...

good luck finding that seal in stock anywhere. Closest O'Reilly to you stocking it is in Arab

use gm syncro mesh. make gear whine a whole lot less noticable than dex/merc 3

synchro mesh is not supposed to be used in the OEM ford tranny's. Dexeon 4 might be synthetic. I don't know.

Thinking about it some more, it probably is not a big deal to not use synthetic fluid. So I wouldn't worry about it.

Synchromesh does not have the friction modifiers that are friendly with fiber lined blocker rings, Synchromesh was designed for transmissions using brass blocker rings. Dexron/Mercon III is next to impossible to find anymore and the newer IV & V are way different in terms of additive packages, I would run C4 hyd fluid before I used Dexron IV or V!!!! Now onto synthetic fluids, They require a special friction modifier to work correctly in a trans with fiber lined blockers. Go find an Allison dealer in your area and get the Allison brand synth auto trans fluid. It comes in 1 gal jugs or 5 gal buckets and for the price is cheaper that going to Vatozone or comparable stores, Plus it has the friction modifiers in it(folic acid based if I remember correctly).
