i know somebody selling an 87 bird 5 speed from a v8 and he doesnt even know what world class means. how can i/we figure this out. if i can easily search and figure it out let me know. i just gotta leave like right now for work but the auction ends soon. thanks a lot.

 

Look at the front.

Is there a real bearing there or not?

I forget the exact ID but comparing a World to a reg T5 and the front bearings are different. Believe the input shaft isnt supported by a true roller type bearing on the non world class T5.

i doubt the guy would know that...plus he has it so i cant look at it. was wc an option in certain years or something?

 

88-up for f-bodys, and i think that was the transition year so maybe not all.. i got mine out of an 88 formula

 

You might consider a search. I recall seeing pics of the visual differences.

again, i dont have the transmissions in front of me...im looking to buy one, most likely over the internet too.

 

I "believe" there's a metal date tag indicating 88-92. Bolt, left side, Torx 50 (Non WC is a 21 mm 6-point). 26 spline for a V8. Seems that the 89-92 LB9 had the .73 5th gear--which is the same as the L69's--which would give a bit more grunt than the .63.

so if its pre 88 then theres no way its a world class, right? thanks for the good info and ill let the sellers know.

 

HTH

 

can someone explain what the difference is between the 5th gear being a .63 rather than a .73. does it change anything else in the trans or is it just a gas mileage saver? what does a bit more grunt mean!!!

 

just a gas mileage thing, but .73 is nicer because 1 > .63 is kind of a steep jump

 

HTH?
