ecm question

[crazycory1]

I just bought an ecm from a 89 camaro tbi five speed. How can I make sure that it came from a five speed car. From what I could find the service numbers for both auto and manual trans are the same.

Open the little cover over the PROM chip and look at the silver sticker on it. What is the lettered code on it?

Ok, heres all the info. The lable on the outside reads:

serv.no.1228746 apty
86apty k390040364
16132231 apty
86atpyk390040364

under the cover plate:

boards that the chip is on reads:
379071303649004

and the lable on the chip reads:
apty
2254


Thanks for any help
