"Clearly, high transaction prices - the new trucks and SUVs are more profitable than the ones they replace - that certainly helps," GM Chief Financial Officer Chuck Stevens said at the company's Detroit headquarters.

The positive results provided a respite from the drumbeat of negative news this year surrounding faulty ignition switches that led to massive recalls and have been blamed for at least 29 deaths.

Shares in the No. 1 U.S. automaker were off 13 cents at $31.18 in midday trade.

Morgan Stanley analyst Adam Jonas lauded GM's "Audi-style" profit margins in North America that approach German luxury levels. However, he added investors should consider exiting the stock, citing a dial-down of European growth and increased pressures on the key U.S. market.

"We believe no (automaker) with global exposure can confidently offer guidance for the 2015 period," he said. "This is not just a GM issue."

Higher pricing on GM's vehicles resulted in a $600 million profit gain in the quarter. It launched new versions of its full-size Chevrolet Silverado and GMC Sierra pickup trucks last year and followed those with other updated SUVs on the same vehicle platform earlier this year.

Stevens said GM remained on or ahead of its financial forecast from January, when it said it would see a slight increase in pretax profit this year.

The quarter did not include any charges for costs related to the record number of recalls this year as GM has already booked them. Chief Executive Officer Mary Barra said GM has repaired more than 1.2 million of the cars recalled for the defective switch, and had enough replacement parts to service the rest.

Net income rose to $1.38 billion, or 81 cents a share, from $698 million, or 45 cents a share, a year earlier.

Excluding one-time items, GM earned 97 cents a share, 2 cents above what analysts expected, according to Thomson Reuters I/B/E/S.

The quarter included $300 million in special items for flood damage sustained at GM's Michigan technical center and the writedown of Russian assets.

Revenue rose slightly to about $39.3 billion from $39 billion. Analysts expected $39.8 billion.

GM reported a profit margin of 9.5 percent in North America, the fifth consecutive quarter of year-over-year growth.

GM said average transaction prices in the U.S. market and vehicle sales in China reached record highs in the quarter. It is getting almost $4,000 more per full-size pickup than it was before the new model was introduced. Stevens expects GM's North American incentive spending to decline in the fourth quarter.

In North America, earnings rose 12 percent to $2.45 billion.

Profit at GM's international operations, including China, fell about 20 percent to $259 million. However, GM's equity income in China rose 14 percent to $484 million.

The loss in Europe, which included $200 million in restructuring costs, widened by about $150 million as the Russian market struggled.

GM posted a loss of $32 million in South America, and CFO Stevens said GM remained focused on cutting costs there.
