At what power level does the 5 speed manual gearbox start to break or become unreliable?

I have a 3.0 TiD,its only available in manual form apparently due to the excessive torque delivered by this engine (is there such a thing as excessive torque?) Hirsch does an ECU upgrade to increade BHP from 186 to around 240, torque also increases by :oops: around 100 ft/pds (or N/M?) My dealer told me that the engine can take the HP, but not the torque and that any warranty would be invalid (still got almost 2 years to run).

I've never heard of any 9-5 gearbox problems on tuned cars.

How about automatic gearbox for 2001 Aero? I think there's an automatic limiter in the system so whatever upgrade you make, you will not be able to transfer more NM to the autogearbox then it can handle.

I wish they did the same system for the pistons. I that some guys who are into extreme side of tuning are pretty much worried about that.

Wow! How much torque does that big diesel make then?
