hi all,,
i need your help and feedback,,
it all started since i rebuilt my 6L90,, only replaced clutch packs (alto for 4-5-6 and 3-5-R),, pistons,, seals and filter,,
i tuned it as per the tuning school guide and tuned stock TC to never lock,, TM was only reduced wisely,,
trans was just fine except for that ,when cold and in the very beginning of a drive, it bucks few times,, it does it in current gear no shifting involved,, by bucking i mean locking (like instant P) the drive train for an unknown reason,, i didn't care enough since it only happens once cold or started the engine on an incline,,
last night,, i pulled WOT running from 3rd up to 5th where drive train disengaged completely,, engine can rev freely,, i pulled over and started over again,, car moved in 1st 2nd and 3rd,, but not for the 4th 5th and 6th,, i guess 4-5-6 clutches engage but car not moving,,
my first guess was a broken 4-5-6 intermediate shaft (stock),, but what confused me is that the bucking became worse enough to hear the tires locking and barking,,
checked oil,, no smell,, no discoloring,, no debris whatsoever,,
please,, help and advise,,
thanks,,
