Tips For Keeping The AOD Transmission In Your Ford Econoline Van Working Strong

Posted by on Monday, December 29th, 2014

The AOD is Ford very first four speed automatic transmission. The AOD stands for Automatic Overdrive.  The AOD transmission is heavily based on the earlier Ford FMX transmission.  In addition to replacing the FMX, it also replaced the C4 and C5 light-duty three-speed transmission.  The AOD first went into production in 1980 and was eventual phased out of production in 1993, at which point it was replaced by the AODE, then the 4R70W and finally the 4R75W. The AOD was equipped with a weak first gear ratio (at least for an overdrive transmission) of on 2.40:1. On the other end of the spectrum, it came with a very sweet overdrive ratio of 0.67:1 (33% over-driven).  The AOD transmission could be found in a very wide range of Ford branded vehicles, including the Thunderbird, the Ford LTD, the Bronco, the Mustang, the Ford F-series pickup trucks and the Ford Crown Victoria. It could also be found in the Ford Econoline.

Upgrading The Performance Of the 4L80E In Your Chevrolet Avalanche Is Easy

Posted by on Thursday, December 25th, 2014

The 4L80E is a very heavy duty four speed automatic transmission designed and built by General Motors. It comes from a family of transmissions that include the 4L85E. Both are heavily based on the original heavy duty Th400 three speed automatic transmission.  For an automatic overdrive transmission, the 4L80E does not feature a very aggressive first gear ratio, only coming in at 2.48:1.  The same can be said for the overdrive gear – it is weak.  It comes in at a ratio of 0.75:1 (25% over driven). This transmission is fully electronic, and uses a variety of sensors and electrical solenoids to control the shifting characteristics of the transmission.

Designed to handle up to 440 Ft-lbs of torque, this transmission is usually found in heavy duty trucks and cars that are heavy in their overall weight. This transmission can be found in many GM vehicles, including the Suburban, the GMC Yukon, the Hummer H1 and the GMC Savana full size van. In addition, it can be found in many non GM vehicles, including the Jaguar XJR, the Jaguar XJ12, the Bentley Eight and the Rolls-Royce Silver Spirit. It can also be found in the Chevrolet Avalanche.

Warning Signs: Why The Steering Wheel on the 2001 F150 Shakes When You Hit the Brakes

Posted by on Wednesday, December 3rd, 2014

The F150 is a very popular pickup truck made by the Ford Motor Company. For many years, it was the best-selling vehicle in America, even outselling cars such as the Honda Accord, Toyota Camry and Nissan Altima. What makes this truck so popular is that it’s available in almost a countless number of configurations. There are three cab configurations available; regular cab, extended cab and crew cab. You can choose from two different bed lengths; short bed and long bed.

It can be ordered with a bare bones plastic interior all the way up to a luxury interior that would rival a Cadillac. Don’t forget about the optional four-wheel drive system, too.  Now add in the fact that you can take your wife out on the town one night, use it the next day to haul hay around your farm and the following day use it to take five kids to football practice. The F150 is comfortable both in 2 feet of snow as it is going down the freeway at 70 mph on a sunny summer day.  All these fact add up to make this one of the most popular vehicles on the market today.

Be sure to keep the brake on your F10 in top shape

Put a 4L80E Transmission In Your 1969 GTO Judge

Posted by on Monday, December 1st, 2014

The 4L80E is a super heavy duty four-speed automatic overdrive transmission built by General Motors.   It is heavily based on the older Turbo Hydromatic 400 3 speed transmission.  The main difference is the number of gears, the gear ratio’s, and the fact that the 4L80E is fully electronic (the TH400 is not).  The electronics in the 4L80E include solenoids used in the valve body, a lock up torque converter and a number of sensors. The 4L80E incorporates a nice 2.48:1 first gear ratio and a generous 0.75:1 overdrive (25% overdrive) gear ratio. This transmission was first put into use in 1991 and stayed in production up through the end of the 2006 model year. The 4L80E transmission could be found in a wide range of both GM and non GM vehicles, including the Jaguar XJ12, the Aston Martin DB7, the Bentley Continental R, the Roll Royce Silver Spirit, the Hummer H1, the Chevrolet Avalanche and the GMC Sierra.

Posted by on Friday, November 28th, 2014

The E40D is a 4-speed automatic overdrive transmission built by the Ford Motor Company. It is heavily based on the C6 3-speed transmission, and is Ford’s first attempt at building an electronically controlled automatic transmission. Both transmissions are considered to be heavy duty in design. The C6 transmission has a first gear ratio of 2.71:1 and an overdrive ratio of 0.71:1 (29% over driven). The 4E0D transmission was designed to help Ford vehicles meet the more restrictive CAFE corporate fuel mileage laws. It was first put into use in 1989 and remained an optional transmission through the end of the 1998 model year, when it was finally replaced by the 4R100 transmission. The E40D could be found in a number of Ford vehicles, including the Ford Bronco, the Ford Expedition and the Ford F-series pickup trucks. It could also be found in the Ford E-series vans.

Lower The Quarter Miles Times In Your 4L60E Equipped Z28 Camaro

Posted by on Wednesday, November 26th, 2014

The 4L60E is a modern four-speed automatic transmission built and designed by the General Motor Corporation. It comes from a a family of transmissions that include the 4L60, 4L60E and 4L65E. All these transmissions are heavily based on a modified version of GM’s first automatic overdrive transmission, the 700R4, which itself is based on the much earlier TH350 three speed transmission. Th 4L60E first saw production in 1993 (in the GMC Vandura and GMC Jimmy) and was eventually taken out of use at the end of the 2008 model year (last used in the Chevrolet Avalanche). The 4L60E is equipped with a perfect first gear ratio of 3.059:1 and a very sweet over drive ratio of 0.7:1 (30% over driven).  The result is good off-the-line performance combined with better gas mileage. The 4L60E automatic transmission could be found in almost every GM car of the time period, including the Sonoma, the Holden Caprice, the Pontiac GTO, the Chevrolet Impala SS, the Chevy Corvette and the GMC Safari van. It could also be found in the Z28 Camaro.

Extend the Life Of the Allison 1000 Transmission in Your 2006 Chevrolet Kodiak Tow Vehicle

Posted by on Monday, November 24th, 2014

The Allison 1000 is a 6-speed double overdrive transmission produced by the Allison Transmission Company in Indianapolis, IN and Baltimore, MD. It comes from a family of similar transmissions that also includes the 2000 and 2400. Early Allison 1000’s were initially 5-speed transmissions, but in 2006 they added a sixth overdrive gear. Somewhat confusingly, the company didn’t change the transmission name when they added the sixth gear. The Allison 1000 is an extremely heavy duty transmission, capable of handling up to 620 lb-ft of torque. Compare this to GM’s highest rated transmission, the 4L80E which can only handle 420 lb-ft of torque. Put into use in 2006, the Allison 1000 transmission is still in production. This heavy duty transmission can be found in all sorts of motor home and custom applications, along with the Chevrolet Silverado, the Hummer H1, the Chevrolet B-Series and the GMC Sierra. It can also be found in the Chevrolet Kodiak and the GMC Topkick.

Winter Driving Tips: Get the U151E Transmission in Your RAV4 Ready for the Cold Weather

Posted by on Thursday, November 20th, 2014

The U151E is a five-speed automatic transmission designed and built by the Toyota Motor Company. It’s a transaxle assembly intended for use in front-wheel drive vehicles. The U515E transmission is very similar to the U151F transmission, with the major difference being that the U151F is designed for four-wheel drive applications. The U151E has a very steep first-gear ratio of 4.235:1 which makes it great for quick take offs, especially when used with small, underpowered engines. On the other end of the spectrum, the U151E has an overdrive ratio of 0.75:1 (24% overdriven) which helps achieve great gas mileage. Toyota first put this transmission into use in 2004 and used it all the way up through the end of the 2012 model year. Toyota used the U151E in many of its branded vehicles, including the Highlander, the Sienna, the Camry and the Avalon. It was also used in the Toyota RAV4.

Off Roading the Dunes: Is Your Ram’s A727 Transmission Up to the Task?

Posted by on Monday, November 17th, 2014

The A727 is a three-speed automatic transmission designed by the Chrysler Corporation. It is mainly found in two-wheel drive vehicles, although it can be used in four-wheel drive applications in conjunction with a transfer case. Internally to Chrysler, the A727 is also referred to as the 36H or the 37HR. Chrysler eventually replaced it with the four-speed A518 and A618 transmissions. Most A727 are purely mechanical transmissions, although some of the later versions incorporated a lockup torque converter that required the use of an electrical solenoid. The A727 is considered a very heavy duty transmission. It was built alongside the A904 transmission, which was a weaker version of the A727. Compared to modern multiple speed transmissions, the A727 comes equipped with a poor first gear ratio choice of 2.45:1. This helps neither mileage nor low-speed take off. The very early A727 transmissions were heavy cast iron units. Starting in 1962, Chrysler started producing the transmission with a lightweight, but strong, aluminum case. Chrysler continued to produce the A727 through 1991, when it was finally replaced because engineers needed a transmission with more gears to meet new strict CAFE mileage laws. The A727 was used widely throughout the many Chrysler brands, and could be found in vehicles like the Hemi-powered Road Runner, the Plymouth Fury station wagon, the big block Dodge Darts, the high speed Dodge Daytona’s and the 340 six-pak Dodge Challengers. Chrysler also used them in Dodge Ram trucks.
