case 1070 moves backword in low range

james1bow · Jul 11, 2015

i have a case 1070 all new ps pistons seals bevel washers oil dist rings clutch and friction plates. tractor shifted fine for about 10 minutes and then low range turned into reverse mid range is good and 3rd range does nothing and lose pressure in 3rd range also. i resplit the tractor and everything seemed ok. ive also isolated each spool and still lose pressure in high range. if i have a spool sticking could it cause these symptoms? any ideas as where to go from here? thanks in advance

These powershifts are rather complicated.
Do you have a repair manual?

Did you dissemble the control valve? There are some small parts that can be lost/missed assembled like the C2-C3 shuttle ball.

the only part of the control valve that was taken apart was the spool caps to clean them.
