[Bradlyk]

Hi Guys,
Long time viewer first time "poster"
I having trouble with my ford 3930 the transmission will work fine for the first 15 minutes of work without stopping for a break but after the 15 minutes are over the FRONT/NEUTRAL/REVERSE lever doesn't seem to work like you can put in gear but when you let go of the clutch it doesn't move
Do any of you guys know what the problem is
Help would be greatly appreciated

Cheers

Are you sure it is the transmission and not the clutch? When the tractor is cold and you do a hard pull is there any slipping of the clutch?

Basically, you have an auto transmission for your forward and revers. My experience with auto trans that quit after a short time, is the suction screen is pluged with clutch materal. If you let it sit for an hour or so, does it work for 15 minets, then stop again. I would be looking for a pluged filter or screen, or4 both.

This is most definitely not an "auto transmission'. It is a gear drive transmission with a mechanical shuttle and dry, single disc clutch. Making incorrect guesses and posting bad information does everyone here a disservice, especially the guy who is seeking help.

Your symptoms match those of a slipping clutch, not a transmission problem. Adjust the clutch operating rod to provide about 1-1/2" of free travel at the pedal. If that doesn't bring back normal operation, you will need a clutch replacement.

Is the operating rod visible? or do I hafto take something apart?

I don't know if this helps diagnosing the problem but before this we were having problems with the HIGH/LOW button not transmission lever but button

From your first post, I thought that you had a hydraulic cluch pack for forward and revers. Now you post that you have a hi-low botton. Now I'm old school, and when I see a botton shift, it's an electrical shifter, that atvates a hydraulic clutch pack. As I'm not familiar with a ford 3930, What kind of trans do you have.

It is a gear drive transmission with a mechanical shuttle and dry, single disc clutch. With a dual power switch.


I brought it in to get fixed the other day and just got called today as the mechanic split'er in half and said it had to witdo h something with the dual power not quite sure yet
Will keep updated and take pics when she gets back
