Concerning the John Deere 6320 tractor throws code 306057.31 I posted last week. I went ahead and spent $288 for the JD tech manual for codes. For this code there was a lot of mumbo jumbo electronic stuff that would take a JD tech to understand and a ton of stuff to check. However one thing it did mention was the transmission enable signal runs thru the k09/05 relay. So I replaced it and it fixed the problem. Of course I went to the dealer and they didn't have one and couldn't even find the correct one on JD parts. So I went to the internet and found one. $12. Who knows what they would have charged me if I had to call for a JD service visit. I'm sure it would have a lot more than $300.
