Hello,
I've searched and found nothing on this issue..
I replaced the front pump boost valve (.471 to a .555) trying to get a better grab on my first to second
shift, I also replace the 1-2 accumulator with a block off plate from ck, and I get a severe vibration on low gear, I even put the .471 back in and the vibration was still there, unloaded on jack stands I get no vibration?
SOOOOO
I rebuilt the transmission with a master rebuild kit,(the clutches and band were cooked,, I know why but that's a different story) I used a .500 boost valve kit in the pump, the front pump had a 13 vane pump assembly, I replaced it with a 10 vane. all clearances are set from the CK performance book,
the vibration is still there, unloaded on jack stands I get no vibration, could the 1-2 block off plate cause the vibration???
Thanks for looking!
Walter
