Rebuilt 904, no 3rd gear???
I had a similar issue when I built mine, no 3rd because it leaked. It's possible that the sealing ring installed on the front pump, the beveled lip got tweaked/installed the lip on top of itself instead of inside, then it broke off... I feel your pain, gonna be going thru mine for the 3rd time soon. Always air check your unit too. PM fishy68 for the air check guide.
Fold like the middle seal in the picture:
Good luck!
