H series tranny???

[shaun]

Does the H series tranny hold up to 400whp or more? If not, what tranny would you use?

 

[posol]

if you have an h-series motor, you have to use an h-series tranny. (or, the f-series, but that would be counter productive)

generally, the tranny will hold fine.
axels break first - there are aftermarket axels
differentials break next - there are nice LSD units that are uber strong.

the rest, really will hold up fine
