Hi all. I bought a mid ‘80s ford 1700 a while back. It’s been a great little workhorse, but I have a recurring issue. Like many of these, the bucket and 3 point hitch were slow and jerky. Drained the tranny, cleaned filter, new fluid. Worked perfect...for about a week or two. Repeated maintenance, again went back to perfect operation, but a couple weeks later, slow and jerky again. I’ve now done this routine 4 times! Filter looks clean, fluid looks ok. Can’t find anywhere air is getting in around the banjo fittings or anywhere! I know hydraulic issues on these have been beat to death, but I couldn’t find this specific issue with a search. I’m kind of out of my depth here, not sure what’s going on? I’ve used a fluid that lists Ford 134 replacement each time, and even a couple of different brands! Any ideas or help would be greatly appreciated!
