I have an 84 Scrambler w/ 360 and TF999 setup, 2.77 gears in the axles and 33" tires. I know i need to get some lower gears, but i would like to drive the jeep in the mean time. I still gets up and goes with this current setup, its only 2900 lbs. My problems is i put the trans in drive and it holds first till about 5200 rpm then it hits second if i stomp on it. It will shift at a lower rpm if i take my foot off the gas or ease up the throttle. Once i'm going about 55 to 60 at 2900 rpms it will not shift into third, even if i take my foot completly off the gas. The trans also will not automatically go back into first at a complete stop. I have to floor it and it starts out in second and then it downshifts to first hard. The trans is freshly rebuilt with a shift kit, and i'm using a Lokar kick down cable. I adjusted the kick down cable by seting its max position with the max throttle position. Its my understanding that kickdown cable is what holds the trans in gear longer or until a higher rpm, but what tells the trans to down shift? I was going up a steep hill in second and my rpms dropped to 1100, and it still didn't downshift.
Any advice would be greatly appreciated? OH, is the case different on a TF999 and a TF904, would like to replace the B&M shifter with a Lokar, but they only list 727 and 904.
