what are the s/c'd joe gibbs 4.8 5spds?
 
what transmission are the 4.8 5spds running that come from the factory supercharged?

everyoen said the 4.8 5spd couldnt handle a lot of power...are they the same trans or no?

that's not what breaks them. they just can't handle speed/power shifting. the syncro's and blocker rings are terrible in them. you can launch it on slicks plenty and not break it. it's the shifting that breaks it.
