use atf. if you look in the chiltons it says dont use gear oil.

 

[94scortlx19]

ive heard so much shiit about chiltons its rediculous... i dont trust them as far as i can throw the book.....

I putted Motorcraft ATX and grinding is finish!

 

[neuspeedescort]

chiltons is a good baseline help. but in any modification or rebuild it leaves parts out. i have been more confused my a chiltons then helped.

just about every ford transmission takes mercon-dexron, manuals/autos. hell even the transfer cases in AWD aerostars take mercon-dexron. mustang 5-speeds take mercon dexron as well....

Chicken grease doesn't work well.

At some point Ford may have produced a tranny that the factory spec'd something other than dexron III but I can remember when. I know the 5 speeds call for dexron III. read the owners manual, hayes manual, chiltons, ask you local ford dealer. They all say dexron III. Most standards use atf fluid nowdays.

Trust when i say this, use 80-90 gear oil. it work wonders on keeping ur tranny down a couple degrees and keeps ur gears intack for long time.

i was told always use what was used when new from the factory which for the escort was mercon/dextron III, otherwise it can mess up syncros and stuff
