Rebuilt 904, no 3rd gear???

Seen this scenario before.....

If you really don't want to be doing this again then do it right this time.

1 Strip and clean it again buy a paper and rubber kit their cheap.
2 Replace the filter use a Dacron one. Change to a screen later if you like.
3 (Assuming its not a lockup TC) Flush it out,pour a lil solvent in, put the fwd drum and spin it a few times then dump or better yet suck out the solvent repeat again.
4 Get a can of cooler flush their cheap too... Flush those lines and rad with it !!
5 Air check.... you should hear a solid apply with very slight air leakage. Very hard to judge with little experience so that will be your judgement call.
6 If you use teflon rings, grease them in... They don't air check too well when greased in tho. Personally i prefer the steel rings (User preference).
7 Make sure the pump halves are lined up.. use a large hose clamp with the pump Oring off. Pump will install better in the case when lined properly.. Less possibility of " broken Rings "
8 New fluid..... I know its tempting but DONT reuse the old fluid.

Last of all ..Haste makes waste
And... Why is there never enough time to do it right, BUT ALWAYS enough time to do it again.... Think about it Good luck

I agree buddy thanks for the tips. I have it all apart and I've been cleaning everything with Kerosine. I did not take apart the sun gears and planetary gear set though. I just put that whole thing in a bucket of solvent and swished it around for a while and turned the shaft every which way.

You think I should take apart the front pump? Guess I could...

I will stay with the Dacron filter. And I will flush out the torque converter with kerosine as well.

I have a B&M plate style trans cooler, not in the radiator. I'll attempt to flush it out with the cooler flush. where do you get it? Napa, Orielly? I havent looked yet. And yes I'll use the steel rings.

If I have any more automatic trans issues after this, I have a complete brand new rebuilt 4 speed setup waiting on stand by. :)
