Trans ID assistance

[LC2 ROD]

My search function isn't working for me.
Is there something for IDing the 3 digit call out on the 200r4 or 2004r trans.
Here are my two transmissions in question.
Both are 2004r
KTF out of a 89 something.
CAF out of a 86 something.

Thank you in advance for any help.

The KTF is probably out of a Cadillac Fleetwood Brougham if it's a 89'
The CAF might be out of a Monte Carlo
