how can you check if your car came with traction lock on a 89 5 speed and a 92 aod auto, and also on an sc auto with traction asist what does that do.
Also 5 speeds have 2.73 gear ratio
and the aod has the 3.27 correct also on a 5 speed rear end the only difference between it and a aod rear end is the half shafts correct.
 
you can check the tag on the door but it may have been swapped out

crawl under the rear of the car and look for the tag on the rear end pumkin

it should say 2L73 and 3L08

L designates it came with limited slip, but the clutch material in the rear ends usually wear out and you get the one wheel spin, change out the rear diff fluid and use some modifier, may help.

89-93 s/c's with aod tranies should have a 3.08 rear end.

94+ with the 4R70 tranies got the 3.27 gears.

half shafts are the same for s/c and v8's. only the 3.8na got the crappy shafts.

sc with traction assist has to be 94+ which should have the 3.27 trak loc
 
wow ok I was always told that the half shafts on the 5 speed (this was by an old member from here) were beefier and the half shafts were thicker any way sounds good did the traction lockers come in the autos too.

This is not correct. All V8 and SC's had 8.8's and V6 NA had 7.5's
89-93 5 speeds had 2.73 and trac loc rear end
89-93 AOD cars had 3.27 and trac lock rear end
94-95 4R70W had 3.08 open rear ends, they used ABS assited traction control, not a trac loc rear end
94-95 5 speed, not sure on this one but believe they had 2.73's also

As 90blkbrd mentioned, the 94-95 4R70W SC's came with 3.31's. Also, some (very few) V6 NA's came with the 8.8".

Otherwise that list looks correct to me.

The beefier half shafts on the 5-speeds were Fords way of trying to eliminate wheel hop with the independent suspension.....:rolleyes:
