737-200 has a procedure as well for Gear Lever Jammed in The UP Position. It involves turning off the controlling hydraulic system pumps and then cycling the Speedbrake Handle to reduce hydraulic pressure below 500 psi, pull the manual gear extension handles and then cycle the speedbrakes until 3 green which could take up to 4 minutes.
