Yesterday my 95 4.0 developed a new problem. I was driving when the gearbox suddenly downshifted to 3rd and began to lose power. I had to mash the gas to keep it at about 40mph. It continued to have no power for about 30 seconds, then surged for about 5 seconds until it was back to normal. It seemed to do it more often around 3rd to 4th, only once did it have no power accelerating from a standstill. My best guess would be a possible torque converter problem, but wouldnt that cause these problems across all gears? Fluid level was fine. Anybody experience any similar symptoms? Any help is greatly appreciated.
