I guess this subject come up once a month or so about how 904 can not hold the power...

i been using a 904 ...the same 904 since 1993 in my 69 Barracuda that has run 10.70s out here in las vegas..

it has been rebuild once back in 2004...

the 904 has the same pump...only part that has broken was the rear sprag due to ring and pinion breaking....

904 has 5 disc in front clutch pac...uses kelvar bands and alto disc/kolene steels..

the big spring in the front clutch pac has been replaced with a 24 spring kit...

been using the same tranzact pro transbrake since 1993...so the poor little 904 is getting slammed with a transbrake too...

got another 904 going on it 4th season...same parts as above in 71 dart that has gone a best of 11.03...while changing engine last month...I took this 904 apart to check it out..everything looked great...just replace sealing rings ...it is back in service...

car is on trailer to go racing tomorrow...

so if you are breaking parts...find another trans guy..or read a book...
