Recently i've read on 5th gens and i see that that the GTS's models are running the 5SFE Engine. 6th Gen GT's are running a newer-ish 5FSE and my big question is if the 6th gen Manual Trans will bolt onto the 5th Gen 5SFE.
5SFE Transmission 6th gen in a 5th gen? - 6G Celicas Forums
it will fit. its actually an upgrade.
It depends on what you are looking for. The S54 out of the 6g has a shorter final drive, which is actually detrimental to highway mileage.
If you are looking for an autox/track/city box, its the better choice.
