Drum Got drilled 0.050 for more pressure?
Blown out seal?
Wrong Direct drum piston?

Raffa...If you have to much more problems... Have you talked to John Cope at Cope Racing Trans? I think he can help get you fixed up.
That's way to much failure there my friend !!!!

Hi Bob ... everything is checked ...i have buy all parts from SMR transmission :

front billet drum
5 gear planetary
billet piston
billet rod
red alto clutch
smr AA valvebodie full manual reverse pattern

i dont have speaked with John Cope because i dont have buy the parts from he

SMR told me that car is too powerful for this transmission

RacerHog

Oh Boy.... If that the case..... Then it looks like it might be time to convert over to the G.M. T.H.400 or the Super Glide, Bruno's, B&J.

I did not think you were up in that H.P. range yet? But when you start getting near that 900 foot pounds of torq. (FPOT)... Then things start getting iffy...

I'm not 100% sure this will fix the problem.... But ask SMR if there is a way to get somemore line pressure to the front drum?

Speaking of line pressure, Ask SMR or A&A what the pressure should be and get a reading from the trans port?

If all is well there... Then I would have to agree that the motor is just over powering the trans.....

Bob i just buyed from John Cope Racing a new valve body that will cure the line pressure in 3rd ... john told me this will be solve my problem ... i will let you know... 14 sept i have the race .. i hope in 9.90 !! im undecided wich modify on front end for high speed .. look like flying

Hope you had a great time here in the USA.... Looks like you and everyone had a great time.... Sorry I could not meet you at NHRA Pomona.
I Hope John Cope Got your trans problem fixed, and no more burning up clutch's in the trans.
On the front suspension.... It you have a Sway bar in the front??? Disconnect it and let the front end travel natural....
A 1.40 60' should get you in the 9.90's or a little better...
Good Luck....
