whats the difference between a 200-R4 and a regular 200-R4?

[Vendor Defendor]

i was wondering what the major differences between a BRF 200-R4 is and an (for Example) AA 200-R4? my BRF is pretty messed up (its the shops fault and everytime i take it back something else goes wrong) and i have thought that it might be easier (and more cost effective) if i find a 200-R4 and build it myself. i have a friend who has built sevral tranny's for his TR's and is willing teach me how to do it.

now i know that i can get AA-tagged tranny's very easily. so what would i need to do in order to get that tranny to shift good? what about a CZ tranny?

thanks for any help

Build the CZ as the calibration is very close to a BR. With the addition of a VB kit and a good servo, you'll be fine. An AA is Cadillac; smoooooth.

What about an OG? What did that come from? How hard or what do you have to do to get it close to a brf? Thanks!!!
