CHEVY SLIPPAGE?

1997 Chevrolet Suburban

Transmission problem
1997 Chevy Suburban V8 Four Wheel Drive Automatic 150000 miles

Hello. I have a K1500 Suburban from 1997. When you put your foot in her she down shifts (i think) and the RPMs go up to about 6000, but there is no reaction in speed or power. The truck does not accelerate. If you drive reasonably for the most part, she works fine, and does not hard shift.

I was recently towing a small horse trailer (empty) over a mountain in VA and she downshifted while going up and the same thing happened. The engine reacted, but the trans and wheels did not.

Depending on the fix, I am thinking about switching to 4.11 gears for towing. Any thoughts for that one as well?

Thanks!
