Posts: 775Thanks Ian is it repairable expensive I am not an auto guy so I’ll have get someone to do it
going to take pan off today and see what I see
December 15, 2018 at 12:20 pm #27649Drop the pan, undo the 4 bolts from the round cover, if it hasn’t gouged up the case it’s a cheap repair.

Hi Ian , removed the pan and cover today and all the bits came out have added photos , can this be repaired in the car or is it trans out also would have bits gone through the trans , cheers Frazer

December 16, 2018 at 5:21 pm #27659The rest of the piston should pull out, I believe there’s an upgrade one available, I’d clean the shrapnel out install the new parts and give it a crack, filter screen should have caught the bulk of it.
One of these>>

Thanks Ian I assume it does not mater 6 cylinder not a v8 also do I have to take the plate off to get snap ring out
I appreciate your help
December 16, 2018 at 9:31 pm #27662Which snap ring?
Do you mean the ring around the broken piston?
I’d drop the valve body and plate anyway to make sure there’s no shrapnel in there hiding, been a long long time since I’ve played in a Trimatic so all a bit foggy sorry.

Posts: 775Thanks Ian I have found a good video on you tube the snap ring or retaining clip is to hole piston in
December 18, 2018 at 6:47 pm #27671Good move Frazer, likely to get up to date info that way as well, as I said been a long time since I played with one!
