I had buy a JAP SPEC Supra TT Tranny and i send it to Boostlogic in Amerika. Boostlogic upgrade the tranny and send it to me.Its a 340 tranny.
A 3040 is the NUMBER on the Tranny.
343 is stronger as 340.
343 have 7 forward clutch and 340 have only 6 clutch.
343 have 5 direct clutch and 340 have only 5 clutch.
340 is good for 500PS and 343 for 1000 PS.(or 550)
As I said before, there's a lot of modifications of A340E. For exapmle, USDM NA MKIV has weakier tranny than TT MKIV's.
And now get ready to listen the truth...

A340E for TT MKIV has the same amount of clutches as A343E. The only difference is the ratio of 4th gear and
possibly some differences in line pressures and electronic nuances.
Andi's photo helped very much and everybody can compare it with this picture
