Exactly what I was thinking, and you could have knocked loose/ or damaged it when you were doing the oil/fitler change. Are you sure you didn't damage the solonoids inside the tranny when you were pulling the pan down and out, they can be damaged very easily.

What about a bad VSS?

ok i checked the trans fuse and is good then i checked the wiring harness and it looks good it is connected to the tranny. i don´t know if there is a ground wire that i should check

[carjimost]

what is the vss? how can i check it

[BlazerLT]

hicle speed sensor.

On a 4x4 I think it is on the transfer case and on a 2x4 it is on the tail shaft of the tranny.

If the computer is not getting the proper signal from it, it will mess things up completely.

Kinda hard to say but that is a good start.
Hook them all back up and clear codes and drive it and see whatit does.
Let us know how it goes.
