Mazdaspeed 6 Transmission upgrade
 

Anyone know of a stronger/more reliable transmission upgrade? I'm looking for a full crate tranny if possible, but any info on this would be great. Thanks.

What's wrong with yours? We have guys pushing >500 whp and theirs are fine. The transmission is probably the most reliable moving part on the car.

I was just curious, nothing is wrong per say, wasn't aware people were getting those numbers with stock transmissions. Thanks for the info.
