[910Bluebird]

Hi everyone, i'm new here and i'm from the Caribbean, Trinidad to be exact. I recently put an RB25DET in a 1986 Nissan Bluebird, but the engine i got from the dealers was a manual transmission and the gearbox was too long so i fitted a 1996 HC34 Nissan Laurel auto tranny, the Laurel also came with an RB25DET, so the tranny bolted right in. My question is do any of you all know the transmission code for the RB25DET tranny? i need the code because i'm upgrading the tranny with a Level 10 Performance Transmission Kit, and they need the tranny code. I checked the tranny but all i saw on it was

jatco corp.
44x14

4Y65528C

and the guys at Level 10 told me that is not the transmission code.
Anyone know the code???

Thanks
