The street and sport gearboxes will give you a 5-speed. As PPiDrive stated, the race trans gives you 6, but if the car already had 6 or more gears, you don’t lose them.
When has what PPiDrive stated been the case before? IIRC in Forza 4, putting a race box on a car that had a 7 or 8-speed transmission would lock out anything above 6th.
PPiDrive stated it in the post immediately preceding my first post in this thread. This is true in FM5 as well as FH2. At least its true about FH2 on the One, I don’t know about the 360 version.
Glad you found it! I’d like to add that the street transmission does not unlock any gearing adjustments in the tune cars screen. The sport trans unlocks final drive gear adjustments only.
Damn lag ate my first reply where I told an enchanting story about how I discovered this
Maybe everyone will be thankful for the abbreviated version though
Tested immediately upon making the discovery. On the freeway I am sure the E63 was getting up towards 330-ish kmh as an AWD with 8 gears,
Immediately after RWD conversion (albeit leaving everything else stock and no final drive tuning) it was around 260-ish kmh, banging on the limiter in 6th with nowhere else to go.
Going from memory, did it about two weeks ago or so.
