Sinse you already have it apart, count and calculate the gear ratios.

a-520 1st= 3.29 .....2nd=2.08.....3rd=1.45.....4th-1.04......5th=.72 differential is usually 3.55:1

a-555 1st=3.00.....2nd=1.89......3rd=1.28.......4th=.94. ....5th-.72 differential ratio of 3.85:1

So that should tell you what you have there.

It looks to be a A555 with a 3.85 FD ring gear is 50T and pin is 13T=3.846 whats got me confused is the date on the tag and how the 5th gear is attached. is it a mini van transmission or ? looks like 87-88 guts. I'm kinda of new to these transmissions.
thanks for the input

Looks like the tag is accurate, and so it was built in 90... I haven't dissected enough 5-speeds to notice anything beyond obvious wear, so....

PS Seems like 3.85 is a pretty aggressive gear, what did it come out of? Might be nice on a car with 17s or tall slicks, it would bring the gearing back in-line...

89 A555 uses a nut and a c-clip at the end of the shaft.

87-88 A555 uses two c-clip at the end of the shaft.
89 Minivan uses 87-88 style A555.

Your is probably a warranty unit made in A555 for a Minivan.

I had one of these in my Daytona, and I thought warranty unit as well.

Looks like 555 gears to me.

That is definitely the 555 coarse cut gearset. Looks normal to me. Date leads me to believe it was a service or warranty replacement unit like has been said before.
