Ford 250-C tractor

Tractor when in 1500 RPM transmission kicks out like you’re in neutral go higher than 1500 RPMs it does not kick out it keeps working fine. And under 1500 RPMs works fine and the tractor only has 1500 hours on it. If anyone could give me some information. Thanks

Assuming you have the torque converter trans?????? have you checked the fluid level in the trans???

Yes all new filter and oil.

I'm not familiar with that model, but I would assume that the service manual has procedures for testing the hydraulic pressure in the transmission. That's the first place I would start. It might have a small internal leak that doesn't allow the pressure to build enough at the lower rpms. so the forward/reverse clutch packs don't engage. If it only has the symptom in forward or reverse, then the leak is likely in the circuit for that particular clutch pack.

Ok thank you. It works good up to 1500 rmps kicks out then go to higher rpms works good.

Just an FYI for those who don't realize that there is also a filter/screen on the bottom of the transmission case on the 8x8 & 4x4 transmission.
this is often not known, or overlooked during services. The screen in my 345C was in dire need of cleaning when I bought it.

Yes I bought a filter and change it and oil . That all good. Thank you though

just a swag, but it sounds like it cuts off due to starvation as it builds up to 1500rpms, then the bypass opens up and returns full flow... or a sticking relief valve sticking as it starts to open at "running " pressure then the addition flow above 1500 rpms overcomes it.. hopefully someone whos been into one will reply.

as your saying it runs below 1500 rpm and above 1500 rpms, but stalls out only at 1500+- rpms...

like a cooler valve??? that sends fluid to the radiator???????

Thanks for all the information. It was the retaining wire on dump switch. Thanks again.
