T50 weird gear set What´s going on?

[Bean]

I'm sorry to disappoint you but Uzelac is right. The TRD gear sets would make shifting from 3rd to 4th the same as stock (with the 3 gear set) or shorter (less drop, with the 5 gear set). The final drive ratio has no influence on the geardrop.
The only way I could explain such a behavior with a stock or TRD box is if your shifting really slow (i.e. loosing a fair amount of speed ~30kmh).
Or as he said shifting from 3rd into 5th (maybe someone fucked up on a rebuild but then I wonder what your 5th gear ratio is)

Can you tell us the speed you're doing in 3rd, 4th and 5th at the same revs (i.e. @ 4000rpm) - that way we can calculate the step ratio between them.

(look at the top speed )

I do the only difference to stock with same 4.3 is in 1st and 2nd gear. The drop line from top of 3rd to the intersection with the 4th gear line is the key and as Uzelac described
