B737-900ER Captain reported right after takeoff the control yoke trim had become inoperative and the flight crew was unable to regain electric trim control. Manually trimming the aircraft was difficult and the reporter mentioned there were two locations in the trim wheel rotation where it felt jammed.

Narrative

The narrative follows: All ground operations were normal. Immediately after takeoff; attempting to trim the aircraft during climb-out; my control yoke trim switches were inoperative. I looked at the pedestal-mounted switches: they were in the normal position. I announced the situation and asked FO to try to trim the aircraft with his switches. His were also inoperative.We continued to fly the departure; keeping the flaps at takeoff configuration (5). After ensuring terrain clearance; we cycled both trim cutout switches several times with no success. I also put the stab trim override switch to override; and reset it to normal after that failed to change our lack of trim. At no point did we regain electric trim control.I then retracted flaps; ran the after-takeoff checklist; and then tried all the prior troubleshooting. Again; no success. There are different trim rates with the trim motor based on flaps up or down. We coordinated with ATC to stay in the ZZZ airspace; took vectors for spacing; a block altitude of 16;000 to 18;000 for terrain clearance; and ran the stabilizer trim inoperative (NG) checklist. I flew the aircraft while FO ran the checklist.Manually trimming the aircraft was extremely difficult. There were two locations in the trim wheel rotation where it felt jammed. These locations were 180 degrees apart. The force required to overcome these two points (which location stayed constant) was very large. I have never felt that kind of resistance in any other manual trim wheel operation. Using unloading maneuvers did not change the sticking." FO and I both regularly work out with weights. This was a SIGNIFICANT reason why were able to successfully operate the manual trim wheel.We configured the aircraft per the checklist; made all required calls and coordination; and commenced the approach; ILS XXL. We established final configuration and speed approximately 15 miles out. After landing; we had Fire/Rescue inspect the brakes; then taxied to the gate to deplane the passengers and let Maintenance take the aircraft."
