Thank you for the suggestion. I had lubed it twice myself, and the dealership tried that 1st. he said if he couldn't get it today, he was doing a Dtac on it and see what deere says. he said with the linkage removed he still had a issue, and would replace the internal return spring ( I had already replaced the external return spring and shock absorber before taking it to deere. also used all deere parts). I have a feeling they will be splitting the tractor on this 1. 😪

Called the dealer today. JD wants them to check the regulators ( forward and reverse) and pump pressures of the hydrostatic transmission . So they ordered a pressure kit. It should be there next week. hopefully this narrows things down.

It has been some time and out of the blue I get a call from the dearship . My loader ( ordered a new 440R loader for the 4700) Had shown up today. And since they know I won't sign the paperwork til we know what's happening with the Transmission. I had a update on the test they conducted on the HST pressure pumps. 1 of the pumps ( they didn't state which 1 , I'm imaging it's the forward 1) is putting out about 1000 psi. the spec is 6000 psi. so they told me next week they will have a parts list and quote to repair it. I looked at new pumps a few weeks back that JD offers as a original replacement and it's close to $1900.00 a pump. $4600.00 for a new Transmission. so we will see. Hopefully next week I can give everyone another update.

Hang in there, my friend. For those of us with that line of tractor (mine is a 4600 - 23 years old), it’s good to understand what can happen. Good luck!

I appreciate that!! hopefully I know something concrete in the next few days. I would really like to get this fixed and back on the farm. I still have my JD 4320 , but it's set up for mostly snow removal right now. come spring both will be out working in the fields . My daughter will primarily be running the 4700 . she really loves its size ( to her it feels smaller then the 4320). I bought the 4700 used , I test drove it and knew there could very well be something up with the transmission, but didn't seem at all terrible to drive. The dealership when they 1st saw it said it was some minor adjustments. And now here we are. Anyways thanks for the support!!
