what is wrong with my transmission?

[fordguy87]

well i posted about a week ago saying my 2nd gear synchros were out and now tonight I took it out for a ride and first gear is sort of making a klunking noise and whining pretty bad. I just put the rebuilt t-5 in 4 months ago and idk whats wrong with it now. I just checked the fluid in it and its full so I really dont know what is making the synchros go bad in 2nd and what ever is wrong in first gear. any ideas? thanks guys

what oil do you have in the tranny? oil can cause premature failure when it comes to syncro's. My bro inlaws trucks tranny was completely rebuilt and the wrong oil was installed by the shop and after 1 drive syncro's went.

 

[fordguy87]

the guy i bought it from told me 80/90 gear oil so thats whats in it because its rebuilt to wc specs.

That's wrong. WC T5s (like 1985+) should have ATF.

 

[Snikt89GT]

Your tranny is probably hosed

1985, Ford introduced the World Class T-5

One last piece of important information. ALL World Class T-5 use ATF oil and NOT heavy gear oil or Redline MTL! All NON-World Class T-5 use 70 wt gear oil.

mine did that the other day, now I have a newer one sitting to be put in tomorrow, yeah you need 2.8Q of atf.

 

[fordguy87]

SOB! so u guys think the transmission is toally hosed. Think i could maybe drain the gear oil and put ATF fluid in and maybe save first gear?

 

[Snikt89GT]

Worth a shot, ATF is cheap. The damage might already be done though?

 

[fordguy87]

yea thats what i'm thinking but i just told my dad yea ATF is cheap might as well try it before i pull the trans again.

 

[v8only]

damn, that guy really ****ed you up. It's hosed...you can try atf, but if it's already making that much noise...

take it back now with the gear oil in and tell him that was his fault for using that oil not ATF
