You didn't post a serial number so just a guess but in the attachment #7 is the screen. Remove the bottom plate of the transmission and remove/clean this screen. You could have a charge pump bad so don't rule this out also. There should be a couple of filters but since you have intermittent operation, get after the screen first. You could very likely need to drop the belly pan for access and they are heavy when filled with dirt, etc.

| There are a couple rubber coupling hoses going to your transmission pump that can be bad or have loose clamps, they are 1 1/2 if you want to replace. 252 916 2927 if you can't get it, I still run 2 Hd16s |

| If it is a early SN, then have to remove transmission belly pan to get to filter, why they did that I have no idea being they had so much room on top, my 16dp Sn 8706 had it like that but I changed mine like the new SNs |
