According to a report filed with the Securities and Exchange Commission, and cited by Automotive News, Jeep plans on fitting its eight-speed automatic transmission to the next-generation Wrangler. Chrysler already uses the ZF-sourced slushbox on the Jeep Grand Cherokee, Ram 1500, Chrysler 300, and versions of the Dodge Challenger, Charger and Durango. But according to the SEC filing, the Auburn Hills automaker intends "to use this transmission in all of our rear-wheel-drive vehicles, except for heavy-duty versions of the Ram pick-up truck and the SRT Viper."
AN says that Chrysler wanted to slot the transmission straight into the current Wrangler, but it wouldn't fit. Between the transmission and shift to aluminum construction, the next-generation Wrangler promises to deliver a significant reduction in fuel consumption. In correspondence with Autoblog, however, company spokesmen declined to comment on the eight-speed's suitability towards either the current Wrangler or the upcoming one.
