PA-32 Cherokee pilot reported lack of landing gear indication during approach. Pilot referenced checklist and landed with all gear down.

Narrative

Prior to being cleared for the ILSXX approach at night; I proceeded to extend the gear after slowing down below gear speed. There was no indication of gear transitioning (no red gear pump light) and never received 3 green lights. I tried to transition the gear lever several times along with checking circuit breakers. Once cleared for the ILSXX; I notified the controller that I was having a gear issue; and the gear would not come down. The controller cancelled the clearance and gave me vectors/altitude to troubleshoot. After a significant amount of time running full emergency checklists several times; continuously using the manual override; and lots of wagging the plane; the best I could do was get a red Gear in Transition light on; but no indication of gear down. Plane aeronautics did not change either to indicate gear down. We decided to burn off fuel since I had a lot of fuel left (about 69 gallons). I left the mixture full rich the entire time burning gas as fast as possible (periodically leaning out). I attempted 2 different fly-bys at the airport Tower; and it was night; to see if they can see gear down (which they did not). After a missed visual approach and circling around; a pilot came on frequency that had my same type plane and had a gear issue in the previous months. The controller worked with both us until he ended up needing to leave due to fuel. He talked me through everything again (POH); which we had already done multiple times; but from a 3rd party perspective. The controller finally gave me a block altitude of 4k-10k and some headings to work out some large maneuvers like steep turns to try and dislodge the gear or relieve the pressure. Given hydraulics hold up the gear; and they are supposed to freefall; the thought was to put G forces on the gear. After all the maneuvers; I still received no indications in the plane that the gear was down other than the red Transition light. After about 2 hours of triage; I decided to go in for a belly landing. The airport ARFF (Airport Rescue and Firefighting) units; county fire trucks; etc. were on standby at airport. After 10 minutes of them setting up; I came in for the landing. My passenger and I had briefed the belly landing several times in the previous 20 minutes. We came in slow at about 83; over the numbers I called out 'door' and the top lock was unlocked by passenger. Right before touching down; I turned everything off (master; etc.); killed the engine by pulling throttle and mixture; and turned off the gas tanks quickly. My passenger opened the door just before we landed and airflow changed and the plane yawed to the right more than I expected. We landed hard expecting a belly landing but sometime along the way the gear actually extended; and we landed on tires. My passenger quickly exited the plane as did I. After speaking with airport ops and fire officials; we decided to start the plane; taxi to hangar and they follow. After trying to start the plane; I ran the batter down enough it would not start the plane. I had the gas still turned off and it wouldn't start. When it was attempting to start; I had 3 green indicators. Since batter was down; the FBO towed the plane to the hangar to clear the runway and let airport ops inspect. Plane was towed back to the hangar and put up for the night. Plane logs were documented and said not to fly. Plane is in hangar until next week when we can get an A&P to start to triage gear mechanicals. At this point in time; I'm not sure what else I could have done until we get the maintenance report.
