Hi, and thanks for the quick response.
Here the numbers I found on this gearbox
is that the TR-6060 or am mistaken!?!, it was taken out of car with SRT8 engine, but nit sure what is the car cuz they don't have it.
and for sure getting fresh build gearbox will be the best idea, but as I told you, I live very far from USA the shipping would cost me the gearbox price, while I got this gearbox with redeculas low price.
