What Year Did Chevy Start Using 6 Speed Transmission

1962-1969 Chevy II 1967-1971.

What year did chevy start using 6 speed transmission. It was an evolution of the Turbo-Hydramatic 400 first produced in October 1963GM 4L80-E transmission. A year later it was announced that the 2018 Chevrolet Tahoe with the Performance Package will also use the transmission. In fact GM was recently slapped with a class action lawsuit over the.

The new 6L90 six-speed electronically controlled automatic transmission is standard in the all new 2007 GMC Sierra and Chevrolet Silverado heavy-duty pickups. Those from 1955-68 may have electric overdrive. To get to the high tow rating our test model had a heavy duty cooling system.

It was smooth spaced right and made the most of the unremarkable pushrod motor. GM and Fords new 10-speed automatic transmission sent waves of excitement throughout the automotive community. I later found out it was sourced from Aisin.

The wheelbase held firm at 130 inches. So far this transmisison has appeared only in conjunction with high-horsepower engines such as the 420. Has non-synchro 1st and a barrel type 23 assembly.

But GM is planning on expanding the use of the 10-speed to four more vehicles in 2018. The ST10 duplicated the current spline configuration length and shifter bolt patterns. Transmission options were a 4-speed 4L60E automatic 1500 only standard from 2007 2009 4-speed 4L80E automatic 2500 only standard 2007 only 6-speed 6L80 automatic 1500 only optional in 2009 standard from 2010 2014 and a 6-speed 6L90 automatic 2500 only standard from 2008 2013.
