904 trans...getting no drive

quick one before i drop the box,
racing last weekend i lost all drive, 1st 2nd but got 3rd with a struggle
no reverse either

it wont set off at all in any gear, , but if i put it in park, turn it off re start i can get slight movement in 1st then it picks up and moves but wont change into 2nd or 3rd
reverse is just a no go at all.

plenty of oil
TCI converter 3000 flash
Turbo action reverse manual valve body
TCI internals

oil smells and looks brown yet its fresh
making a horrible noise in neutral (suppose like a banging but not heavy like loose)

pump? converter? bands? all of it :wack:

any help prior to stripout
