5.3 power?

[Yukongk]

Had 6 adults (including me) in my Yuk today and some luggages. Was taking some back roads on a road trip and hit a pretty steep hill. Felt like my Yuk was struggling, I had my gas pedal to the floor, and was barely able to maintain 30mph. Is this normal for a 5.3 in 2001? Should I have manually shifted into 2 or 1?

Thanks,

Sounds like there is something wrong unless you were going up a really steep incline and all 6 of you and luggage weigh A LOT!!

If you had the pedal to the floor, shouldn't it have downshifted on its own?

No it's not.
How much together roughly did all people weigh? And then how much weight in luggage? Also what kind of. Grade was the hill? And how hot was it outside?

To the floor and still 30 seems wrong.......but depends on the above conditions

Hmmm.... did you happen to have a 10,000lb trailer hiding behind you? Definitely doesn't sound right, unless your passsengers were elephants hitching a ride from the zoo. Might wanna check your cats and fuel pump...

People= ~1,000lbs
Luggage = 100lbs
Not sure what grade the hill was, but a fairly steep incline, much steeper than all the other hills I drove on without issues today.
It was about 88 degrees and I had the front and rear A/C going.

Had fuel pump changed last month. Tune up 2 months ago. Cleaned my air filter 2 months ago.

I'm thinking if I would have let off the gas, and pressed on it that I may have downshifted ( maybe the tranny got confused)?

Were you in the mountain s?

Air is thinner up there.

Coolant temperature? Was it almost at the red line? It sounds like u hit engine thermal protection mode

 

[Yukongk]

Yes I was in the Pennsylvania mountains.

I didn't check my engine coolant temp and didn't even look at my rpms, will do if it happens again..

I have less power with the A/C running, wondering if it would have been a significant difference with it off.
