1995 jimmy transmission problem

[c.martin13]

1 have a 1995 jimmy with a 4.3 4x4 in it. I was plowing the other night and all of a sudden the transmisission is slipping in it.if a am at low speeds and from take off it is okay, but after getting up some speed like 50-70 Kilometers it justs revs up high and hardly works when pressing on the gas until you let off on it, it seems to be like a problem with the passing gear, I had no worning leeding up to this problem, any help would be great, thanks

Snow plowing or getting stuck in the snow does things like that.
It sounds like it is done for.

Is it is full of fluid and fluid not burnt?

You need to get it on a transmission capable scanner and check it out.
Check for codes and check the slippage readings and shift times.
Post back what the scanner shows.
Also drop pan and check filter and for metal/and or clutch stuff in bottom of pan.

Let us know what you find.
