3rd gear problem not fixed...
« on: April 12, 2010 - 09:36:32 AM »
This past weekend I dropped my 904 because 3rd gear seamed to be slipping as I would shift into 3rd. At full throttle I would shift into D and engine would Rev up then catch going back down in rpm and climb back up like normal. Now I am not a transmission person and have very basic knowlage of how these things work. The best guess that I had was that the Clutch packs were going bad.

So Saturday I pulled my pump and clutch packs out of the front and replaced all of the disks and seals. (forgive me if I am calling anytihng by the wrong name) I didnt touch anything below or behind that besides the filter.

Then Sunday I put my transmission back in and took it for a spin. Sadly the problem hasnt been fixed and thrid gear still has that same problem. Now my best guess would be something is sticking in the valve body? Anyone else have an Idea on what the problem could be?

Not really. The only thing that I have that's close is parts from a Dakota Transmission back at home.

Were the third gear clutches hurt at all?

From what I saw I don't think so. You could tell that some of the material had defiantly been taken off but there was enough there where it should have been functioning correctly. (At least I think so) I kept the old ones and I can get pics if anyone wants to see.

I had a Friend of mine just take a look at what was going on with the transmission. I told him what I had replaced and the steps that I had taken to do it. And it looks like I have may of missed one... I forget witch set it was but I guess there was a piston at the bottom of one. So I never ended up doing that seal. My friend told me that if this was worn at all that this seal could cause the poor shifting into third. Think that this may be my problem?

Those are smoked!
Did you check BOTH lip seals in that drum?
Is the bushing good.
Are the two sealing rings on the pump stator good and tight fit in the grooves??
What about end play?
Did you change any drums or pumps in the past on this trans?

Wow. lol I though those were just a little worn lol. The bushing was good and end play seemed alright. I dont think any of pumps or drums have been changed. So on a scale of one to ten. How bad is it?

Dude, those suckers are toast. The steels tell the story. All those burn marks on the steels are from extreme heat caused by slipping. I'd say you need a total overhaul.
