On I40 heading west questions power on inclines

Question

We have a gas V10. While going up these hills our engine is downshifting. Is this common?? And while going down 80 is the top speed.

Soooo is this normal. Our first big trip.

Hubby wants to know if DPS have the same issue of down shifting while going up hill.

We do have our toad 2011 2dr jeep.

Actually, it is your transmission that is downshifting and yes this is normal. The diesel pushers also downshift when needed although like any vehicle, you have the means to manually downshift going up or downhill as needed.

Down shifting while going up hills is not an "issue"...(it's often a "necessity").

So Hubster wants to know do you guys shift yours down to 3rd? Or just let the rv do it?

Thank you so much!!

You go 80 downhill? Class A tires are rated to a max speed of 75mph!

Slow down there, Mario.

Oh I guess we are in a bit of a hurry. We slow Happee down a bit. Thanks for that info.

Your transmission will do it automatically when needed when going up mountains or very steep hills. However, I manually downshift when approaching a stop sign or red traffic signal. That helps save wear on the brakes. After coming to a complete stop at the stop sign or stop light, you need to manually shift back to (D)rive to start up again.

All I can say is WOW

So glad I am not traveling around the OP.

80mph in an RV, really smart

Glad you did slow down, and not take it personal

[RayChez1]

Yes it is normal for any coach to shift down automatically.

Eighty mph on a motor home is insane.

And about 6-7 mph slower than mine will go on a flat/level highway.

70 was a bit for me. I feel my most comfortable at 60 to 65. And when I was at 70 class A MHS whipped by passing me. I drive a big class c daily but my speed never goes over 60. Speed limit limitations.
I did not know the tires had a 75 mph limit.
The 80 was going down hill not an intentional speed.

You really need to down shift at the top of the hill and try and keep ur speed closer to 45-50 going down....

Imagine a blow out at 80.... Disaster waiting to happen...

Going uphill on steep grades I just put it in 3rd gear and slow down to about 45 Where the engine isn't screaming at me at 5500 RPM. 4000 RPM is a nice steady climb. If you start down a hill At 65 miles an hour It's quite possible your transmission will not downshift Because of your speed and that is how it runs away with you at 80 Miles an hour. Make sure your in 3rd And the transmission has downshifted As you crest the top of the Hill Before you begin your plummet .

Thank you. I appreciate your thoughts. Yep Hubster was driving he didn't have the cruise set.
