Getrag 260 sport identification

[ambre]

New to the forum

I owned a 325i produced in Oct 1986. Many options including mtech1 and sport gearbox according to the VIN number. I am trying to confirm the gearbox is indeed a getrag 260 sport. According to the drivetrain wiki page I should find a serial number with 6 numbers + 2 or 3 letters. For a sport gearbox I should found TNN or HM. The number I found on the bellhousing is 000335NN so NN not TNN. Any one could help me to confirm if this a sport gearbox ?

Curious. 15NW was 5 speed, 50TNN was sport, 15TNW again 5 speed, 05ANB 5 speed, 52HM sport, 15TNW 5 speed but I cannot find any mention of NN alone.

Perhaps Barry or Pete might be able to assist.

Thanks. Long time I noted the number I will check again the number over the week-end

I checked again and 000335 NN is correct

I should have mentioned the car was produced for the French market. Not sure if letters varied from one country to another

Looking forward to solve this. thanks in advance for your help!
