Looking at purchasing a 2000 KJ Verada through auction but my broker tells me its 'clunky' when changing gears.
Alright worst case scenario new tranny .....

How much am I realistically looking at ?

You're up for around $1000 for a 2nd hand box put in by a mechanic.

Depends on few things, like your mechanic, availability of box, and which box you are talking about (tip tronic etc) and km.

If it's a KJ then it's 4sp tippy
