ABS light and...

[6POINTO]

leaking rear differential

The tow/haul switch was flashing, ABS light was on, speedo wasn't working, and the truck would not accelerate. I replaced a VSS on the top of the transmission ( at the rear of the trans). The tow/haul switch stopped flashing, and the truck accelerated. But, it only accelerates for about a minute, then bogs. If I pull off to the side of the road, turn the truck off, and re-start it, it will accelerate hard again, then bog. The problems that still exist are:

No speedo
ABS light on
Rear differential leaking from bottom of pumpkin
and trans is now leaking

Is it possibly the sensor on top of the pumpkin?

My ABS light came on a few times while on the highway. The last time I noticed th Speedo needle droped off and back up and then the light came on. On a 6 speed where should I look for the problem.
