That pics is like was my Ge after it's oil leak! your one got a massive oil leak ! This is a link I always post when someone talks about transmission or seals replacing, that is very simple and helped me alot while I had to change my lower oil seal, as said I learned GE FF sooner or later tends to leak oil when seals get worn, it does not necessarily means that your tranny is getting trash unless it is the tub seal (not the boot) that went, that would let water getting in the transmission and ruin it...
From what you're describing looks like you might have a belt or clutch issue but not exclude that tranny is a little stuck someway and motor is on effort, also to do not exclude that maybe is stuck cuz it got water inside and gears got rusted! Surely is the fact it got an evident oil leak!
Replacing a transmission on a filter is harder to expalin rather than do it actually but I know it sounds so at start, what you might meet during replacing would be stuck basket bolts from lime etc... as happened to me, it kept 3 days of continuos torching and pounding and a good amount of Wd 40 and Pb Blaster....but I managed, harder part will also be finding a good GE tranny and figure out the exact one you'll need for your model including spline for actiavtor spiral agitator and size, I found some on ebay time ago but they all were not for my model (it was when I thought I had to replace it, I didn't have need luckily)......
A kind member now became a very good friend, Eddy, helped me alot and also sent me the spare seal I needed, I will never stop thanking him!
The link I mentioned that helped me alot also is about a Beaumark canadian washer which internally is exactly the same as a Ge Filter-flo as it was made by them.....
To note that if your washer will work with a new belt and you'll discover your tranny it is still good, you might also replace the seal from the bottom it will be more easy on a side but harder from another as it is very close in there, all you need is to remove pulley unscrewing the bolt, tear out oil seal and replenish with oil enough thick with a syringue or by pouring it very slowly, dont remeber the right thicness needed but I fill rescue the info if you need it, I anyway suggest you to follow the way in the link so you will see how many oil it lost and it's left (it must not be completely full, little more than half gearbox), If you decide to do that from bottom be sure you'll have your machine on it's side with the bottow facing a little upwards
Good luck!
