I discovered CA-2 North, a fantastic mountain road that winds up the San Gabriel Mountains today. I didn't take it long, but on the way up, I noticed that the transmission felt sluggish and monotonous (it felt like a strain but the RPMs were fine). The entire road is 55 miles, would I be hurting my car doing that? Do transmissions get hot or damaged on long inclines? (I was going 45-50 MPH)<p>The fluids are all clean and topped up and my tires are properly inflated. Perhaps it felt strange as I'm used to crusing down the flat freeways. Has anyone else taken their S70 or simmilar on an upwards drive for 55 miles?

Re: Driving steady inclines (JRL)

By glitchy trans. do you mean the ETB? If I were to drive this 55-65 mile inclined trek in my unloaded S70, do you think I would have a problem? I saw a lot of econoboxes going up on my way down, so I would like to think that my Volvo could tackle such a feat with more finesse, but I don't want to do any damage...

Re: Driving steady inclines (Cabot)

The ETB (Electronic Throttle Body) has very little to do with the transmission. I think JRL may be referring to the fact that some of these transmissions have had issues. <p>Anyway, I would not worry about it. It seems like you are more used to driving on flat ground than hills. The NA motor with an automatic will feel relatively lethargic on sustained climbs. At least that was my experience when I drove my fully laden 850 up Mt. Washington several years ago. <BR><BR>

Re: Driving steady inclines (Wayne T5)

How was the Mt. Washington drive?<p>There was certainly a lethargic feeling. If I pushed the pedal a little further, the gear would jump but acceleration was still unusual. At least it kept me at the speed limit. <br>It sounds like the consensus here is that this trip up CA-2N won't damage anything, especially if the car has me and a camera as cargo. The only time I ever had an issue with the drivetrain was when the throttle body was dirty. My transmission so far hasn't been quirky.

Re: Driving steady inclines (Cabot)

Mt. Washington was great. We were in town for a wedding so me made the drive up (should have been hiking but we were too lazy). <p>Just need to keep in mind the NA car's 162 hp are pushing 3,200-3,400 lbs up a hill- not easy to do.

Cabot:<p>Agreed, about that drive being one of the finer mountain routes here in So Cal. <p>I've driven my NA S70 regularly, up Hwy 18 in the San Bernardino Mtns, for the past 6 years w/ no problem. With the non-turbo's lack of power, it certainly felt sluggish, but I kept my patience & have never had any problems, even with my 2 sons (250 lbs between the 2) and a couple of suitcases.<p>I now take my T5 manual, and the turbo eats that mountain up like nobody's business! Still, I wouldn't hesitate to take the 166k N/A up if I needed to.<p>Consider checking out Hwy 18. There are some nice mountain communities up there (Lake Gregory/Crestline, Lake Arrowhead, Big Bear...etc).

Re: (Taleof2Bricks2)

This is purely anecdotal, but I've also been told that normally aspirated engines suffer a bit at higher altitudes and are air-deprived because of the thinner atmosphere, and that because the turbos are actively sucking air and pumping it in, they're able to "breathe better" up there. One regular at an old job of mine used to love coming in and bragging about his T5 blowing past Camaro's and Mustangs on long climbs into the Sierras. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0">

I feel better knowing that someone with the same car as me has made successful trips without problems. I'll check out HWY 18. I'm always looking for pretty and realatively isolated drives to get away from LA and take a break from USC for a weekend.

From USC, I10 east to I215 north to Hwy 30/"Mountain Resorts", 2nd exit is Waterman Ave/Hwy 30, turn left & this turns into Hwy 18.<p>A little over an hour from USC to the base of the mountain, and the hardest part of the climb has 2 lanes, so you can cruise in the right lane.<p>Assuming your car is serviced regularly, you should be fine. I've made at least 30 round trips up to the 5500 ft elevation & a 1/2 a dozen up to 7500 ft with the non-turbo.
