Here is all the info in once place:TRD
: Replaces entire shift assembly in 2000-early 2001 6 speed GTS only. Can be used as a rod replacement in all other 7th gen Celicas, GT and GTS. Not very short, but SUPER smooth shifts.
B&M: Can be used in any MY GT or GTS as a rod replacement. Shortest throws, taller than B&M and easier to use because of greater leverage. Higest Price
TWM: Shortest rod, shorter throws than TRD
, harder to use because of less leverage.
I have used TRD
and TWM, and B&M in another car. The TWM is really the best, it makes the car feel like it should. Tight, direct shifts.
