Beef Up the 4L80E Transmission in Your Chevrolet 3500 Flatbed Work Truck

Posted by on Thursday, August 21st, 2014

The 4L80E is a heavy-duty, four-speed automatic transmission built by General Motors. This transmission was used in models built from 1991 through 2006. This was General Motors’ heaviest duty automatic transmission available during this time period. It was capable of handling up to 460 lb ft of torque and was used in vehicles with a weight rating up to 18,000 lbs.

The 4L80E came with a 2.48:1 ratio first gear and a generous 0.75:1 ratio (25% overdrive) final gear ratio. This transmission was designed to use a quality aluminum transmission case, and included a complete electronic valve body and an electronic lock-up torque converter. The 4L80E was deigned to help vehicles meet the ever-increasing CAFÉ mileage requirements put in place by the US government.

This transmission was used in a number of heavy-duty GM vehicles, including the Avalanche, the Suburban, the GMC Yukon XL, the Chevrolet Express van, and the GMC Savana. It was also used in many Chevrolet Silverado flatbed work pickup trucks.

Proper Care Will Extend The Life Of Your Mercury Capri C4 Transmission

Posted by on Tuesday, August 19th, 2014

The C4 is a light duty three-speed transmission designed and built by the Ford Motor Company. It was designed to replace the Ford-O-Matic and was eventually replaced by the AOD transmission. The C4 shares much in common with the another transmission; the C5 transmission, which is really nothing more than a C4 with a different valve body and a lock-up torque converter. There are basically four different C4 transmissions, which are different only by the number of splines on both the input and output shafts. The C4 was designed for vehicles with longitudinally front-mounted engines and rear-wheel drive, although they can be found in four-wheel drive application when used in conjunction with a transfer case. The C4 first went into production in 1964, and had an incredible (at least for a modern automatic transmission) lifespan that lasted all the way through the 1982 model year. In the more than 18 years of production, millions of these transmissions were built.  The could be found in almost every Ford vehicle of the time period, including the Bronco, the Cortina, the F-series pickup trucks, the Fairlane, the Fairmont, the Falcon, the Granada, the LTD, the Maverick and many more. It was even found in the Mercury Capri.

Great Performance Tips For the TH350 Transmission in Your 1977 Corvette

Posted by on Monday, August 18th, 2014

The TH350 is a three speed automatic transmission designed and built by General Motors. It is a medium duty transmission that falls below the TH400 in strength. This transmission was designed to work in vehicles with a front mounted engine and a rear wheel drive configuration, although it can also be used in four wheel drive applications in conjunction with a bolt on transfer case.  This transmission is fairly basic as far as modern automatic transmissions go, lacking both an electronic valve body and lockup torque converter. The TH350 features a non-impressive first gear ratio of 2.52:1, hardly making it ideal for quick off the line starts. On the other end, third gear is a basic 1:1 ratio, which does nothing to improve gas mileage or the drivability of the vehicle.

The Th350 transmission was first put into use in 1969, replacing the inferior Powerglide two-speed transmission. It remained in the lineup through the late 1970’s until it was replaced with the Th350C, basically a TH350 with a lockup torque converter. This transmission could be found at one time, or another in almost every vehicle that GM made, including the Impala, the C10 pickup truck, the Suburban, the Blazer, the Camaro, the Firebird, the Cutlass, and the iconic 1977 Corvette.

Towing A Camping Trailer? Don’t Let The A750F Transmission In Your Tacoma Overheat

Posted by on Friday, August 15th, 2014

The A750F is a five-speed automatic transmission designed and built by the Toyota Motors Corporation.  It is designed exclusively for use in four-wheel drive vehicles. This is a modern aluminum transmission that incorporates a full electronically controlled valve body and a lock-up torque converter. It relies on data from a number of different sensors mounted on the host vehicle.  The A750F used a very steep first gear ratio of 3.38:1 (great for towing) and a very nice overdrive fifth gear of 0.71:1. This transmission was first put into service in 2003 and remains in production today.  It comes from a family of 7XX transmissions that include the A750E, the A760E, the A760F, the A760H and the A761E. Some are five-speed transmissions, and some are six-speed transmissions. The A750F can be found in a number of trucks made by Toyota, including the 4Runner, the FJ Cruiser, the Tundra, the Land Cruiser, the GX470, the LX470, the Hilux, the Fortuner, and also– the Tacoma pickup truck.

Protect the 4L60 Transmission in Your GMC Typhoon

Posted by on Thursday, August 14th, 2014

The 4L60 is a four-speed automatic overdrive transmission designed and built by General Motors. It is one of GM’s very first automatic overdrive transmissions. It first went into production in 1982 and remained in the lineup into the 1990s. This transmission comes from a family that includes the 700R4, the 4L60E, the 4L65E, and the 4L70E.

The 4L60 came equipped with a 3.06:1 first gear ratio and a 0.69:1 overdrive gear ratio. For the most part, the 4L60 was a purely mechanical transmission with the exception of an electronic neutral safety switch and an electronic lockup torque converter. The 4L60 was introduced during a time when gas prices were ever-increasing and designed to replace the TH350 three-speed transmission. Many a Th350 has been replaced with 700R4 transmissions in an attempt to build a car that’s more drivable.

The 4L60 could be found in a variety of vehicles including the Chevy Blazer, the GMC Jimmy, the Corvette, the Impala, the Firebird, the Camaro, and the Suburban. It was also found in the GMC Typhoon.

Beef Up the A727 Transmission in Your Winnebago Motorhome

Posted by on Tuesday, August 12th, 2014

The A727 is a three-speed automatic transmission developed and produced by the Chrysler Corporation. It was originally called the A488 and built from heavy cast iron. In the early 1960s, Chrysler started producing the transmission with a much lighter aluminum case and called it the A727. It is sometimes also referred to as the 36RH transmission.

This transmission is equipped with a fairly average 2.45:1 ratio first gear and an industry standard (for the time period) 1:1 ratio final 3rd gear. The A727 underwent light changes throughout its life cycle, with the most dramatic being the introduction of a lockup torque converter in the late 1970s. The lockup converter was the first attempt to use changes to the transmission to increase gas mileage. The A727 was eventually replaced by the A518 transmission that incorporated a 4th overdrive gear.

The A727 transmission could be found in a very wide variety of vehicles, including the Dodge Ram pickup, the Dodge Ram Van, the Ramcharger, the Cornet, the Cuda, the Diplomat, and the Aspen. It could also be found in the chassis that were supplied to many of the motorhome builders of the time.

Posted by on Friday, August 8th, 2014

The H5 is a five-speed automatic transmission made by the Honda Corporation. It was designed exclusively for use in front-wheel drive vehicles and was Honda’s very first five-speed transmission. It was first used in a production vehicle back in 2000 and remained in the Honda lineup for just six years before being replaced by the more modern B7XA and MPYA transmissions. It came with two overdrive gears that were designed to keep the motor in a more narrow rpm range in an attempt to maximize gas mileage.
