My dad has a 2500 hd 6.0 gas with i think a 4L80E (not positive) that just today started shifting hard. Truck just turned 100,000 miles completely stock. Trans temps looked normal on the gauge, we were just driving normal not towing anything.

The 1-2 shift will make you think the truck has a shift kit, 2-3 isnt quite so bad but its pretty noticeable. Fluid level was checked and to me it looked higher than normal.

There is a check engine light on but i dont have a scanner to check it. I will tomorrow.

Any ideas? PM me if you want.

Thanks
