I hope someone can help me with this.

I have a 92 silverado truck. About 7 months ago I had the transmission repaired and since then I have been noticing a "jump" in the first and second gears. I took it back and told them about the problem but they claim it is normal for this type of truck to do that. Is it really normal to hear and feel that "jump" in those two gears?

 

Maybe needs a shift kit? They are designed to reduce the shift overlap so it shifts smoother and reduces wear on the transmission.

 

No, of course it's not normal. I'll bet this hacker put a shift kit in your transmission.

It might be the Throttle Valve cable out of adjustment. It's a 700R4 transmission? line pressure is controlled by cable position. Or it has modifications in valve body like a shift kit. Just another idea.
