John Deere 425 transmission issue

[JoeJoeL]

Another individual I talked with several years ago had a similar problem on a high hour machine. It turned out that he had never changed the transaxle fluid or filter. That fixed his problem. I've also seen plugged filters on automatic transmissions on cars do the same before the electronic controls came out.

I wish that was my problem. I change the hydraulic fluid and Filter about every 3 years and only use JD low viscosity High Gaurd.

The 4X5 series has the Tuff-Torq Pro IHT units. I have attached the K92 which I believe is close to the K91, which is listed as the unit in the series. Tuff-Torq has a lot of units on its web site that can be downloaded.

Looking in the troubleshooting section located in the last few pages for ideas.

You say you have service/shop manual. Does it have TM1517 on the cover?

Thank you I will take a look and get back to you shortly. I'm hoping that it's only the hydraulic pump getting tired when the PTO is engaged. Will likely need to buy a hydraulic pressure gauge to confirm. I'm sure the manual will take me through it step-by-step. Last time I used the manual was when I swapped out the plastic gear a long time ago. Need to go fetch it and dust the cobwebs off of it

Yes the Technical Manual is TM1517 SEPT 99
And the Serial Number is 070000
