I have a 4640 with Quad range. When i shift from 1-2 or 3-4 it seems to slip in . I dont notice a drop in speed but it isnt a hard firm shift like our other QR tractors. If the clutch pressure is low- can it be adjusted? I havent thrown a gauge on it yet so I dont know where it is at on pressure. It does seem worse with the oil cold.Downshifting 2-1 or 4-3 is very firm. Any thoughts ?
Thanks.
 
It should shift firm both ways, pressure should be near 165psi..can you make it slip in a higher gear when you shift to the high side...
 
Yes it seems softer in a higher range. It doesnt feel like a long slip - just seems soft going in . Does that make sense? I can stand on the brakes and the engine drags down. I think it is starting to whine in low also.
Thanks
 
I need to take time and check it out. We kinda run it back in the corner of the shed and been using another tractor.Thank you very much for your expertise.
