O.K. first post here on your forums and looking for some help on the disassembly of my 2004r. I have the tranny pretty much torn down but I cannot get the overdrive ring gear/plantary off of the turbine shaft. Is there a snap ring I am missing or is there some trick to get these off. I have to replace the planetary and need to see if the turbine shaft or ring gear was damamged as well. Thanks for the help!

Do you have it out of the trans? I believe there is a snap ring on the shaft. Have you removed it?

If I am understanding you correctly, the turbine(input) shaft is held to the OD planet by a snap ring. Remove the snap ring and the input shaft will pull out the front of the overrun clutch housing. Then you will be able to remove the OD planet.
Yes it is out of the trans. I took off the snap ring
Yes it is out of. The trans and the snap ring is removed from the drum.

The snap ring in the drum removes the Overrun clutches. Remove the snap ring in the picture on end of input shaft.
It there only one snap ring?
Ok I can't see that one the ring gear will not come off
I'll post a pic when I get home.

In David's pic you can see the snap ring on the shaft right at the planetary housing. Right at the end of the teeth in the shaft before it transitions to smaller and smooth.

Yep the problem is the ring gear will not come off. I think it needs some 5 lbs persuasion.

Look close at the rest of the hard parts. The sprags and pump parts especially if that much metal got circulated.

I have. Looks like the damage was contained to only the planetary. Got real lucky on that one and all other parts are looking just fine. I will replace all the clutches steels, bushings and soft parts after a thourogh cleaning. The 1-2 acumulator spring broke as well. That is all that I have seen thus far but I still have a bit of tear down of the internals to do yet. Just need to decided if a rebuild or replacement is in order.
So what is your guys choise on vendor for a performance rebuild kit and a beefed up OD planetary gear? Oh I need a new torque converter as well. around 2000-2500 rmp (lock up) I am not going to use the one I had with all the metal that was in the trans. I have a 450 HP/Tq engine that will be in front of it with an additional 250 shot on track days. This tranny was a level three from BTO. It survived for 7 years behind that engine. I believe the cause was the filter fell out of the pump and starved the tranny of fluid. ( when I dropped the pan the filter was in the pan with no o-ring to keep it in place) I already tore the pump apart and the impellar was gone. I have a new pump (TCI) already to go in.
