Transmission identification

[decision4life]

I have had a creeping suspicion for a while that my trans wasnt a gsr trans but im not for sure. When im going seventy my rpms are dead on 4k with stock wheels and tire sizes. Ive read that some say thats what a gsr trans runs but others say it is an itr. I do know for a fact that it is lsd but nothin else. I cant see an id on the case except for that it is off of a dc2. Any input is greatly appreciated.

you have no id on it but you know its from a dc2? how do you know its from a dc2? jdm gsr trans come with an lsd so possibly it is gsr.. idk.. count the teeth and find out.. or compare you gear ratios..

It has the serial number but I can only make out the first part where it says dc2 and nothin after, its currently on the car so i cant go any deeper than mph vs rpm. I was hoping someone with a gsr trans could chime in on their rpm at say 50, 60, and 70 mph in 5th so i would know for sure.

well i am looking for a gsr trans.. preferably jdm cuz i want the lsd... i think the gsr transmission is longer in the last two gears? i think.. not sure.. but i know my ls trans is at or a little over 3k at 60mph.. if this help..
