Transmission question/help
I have a turbo 99 p11, today marked the 2nd time in 2 years that I've blown 3rd gear out. I understand with turbo, people recommended the "stronger" transmissions from the 01-02 p11s/b15s. I've changed the stacks with b13 ones last time when 3rd went out. This time I'm confused about what should I do with transmission choices, pretty much need a faster/easier way to get it fixed cause my p11 is my only way to work and such. I've read about using q18 stacks, but that only works with the newer transmissions. I know the p11s are the better gear ratios for turbo, but I get confused when people tell me to just get q18 stacks, then after reading threads today, it will only work if I had the RS5F70V trans. Basically, I'm trying to ask for advice, just TRY and find the RS5F70V from a p11 and bolt it right in, or do something about changing the stacks, again. any kind of advice will really help me out.
