Why is the 545RFE Transmission in My Jeep Wrangler Slipping?

Posted by on Monday, September 15th, 2014

The 545RFE is a five-speed automatic transmission built by the Chrysler Corporation. It shares many of its internal and external parts with the four-speed automatic 45RFE transmission. Both transmissions use a modern lightweight aluminum case, an electronic valve body and a lock up torque converter. The 545RFE transmission comes with a 3:1 first gear ratio that helps get the vehicles it’s in moving off the line quicker. It has double overdrive gears of 0.75:1 (25% overdrive) and 0.67:1 (33% overdrive) that greatly help in improving gas mileage and drivability. First put into use in 2001, the 545RFE transmission is still produced today. This transmission is used in many vehicles, including the Jeep Grand Cherokee, the Jeep Liberty, the Jeep Commander, the Dodge Ram pickup truck, the Dodge Power Wagon pickup truck, the Dodge Dakota and the Dodge Durango.

Cold weather can kill your transmission, so you must take caution when driving your car in cold weather.

While it may not feel like it in some parts of the country, Fall is nearly upon us, which means low temperatures are just around the corner. Living in a colder climate can bring with it a number of unique issues, especially when it comes to transmissions. Like any precision instrument, there is only so much environmental pressure they can take before they start to break and fail. Knowing what can happen, though, can help you avoid the long-term consequences of not dealing with these problems early on.

What’s That Thumping Noise Coming from the C6 Transmission in My Ford Bronco?

Posted by on Thursday, September 11th, 2014

The C6 is a very sturdy three-speed automatic transmission made by the Ford Motor Co. Except for a very modest neutral switch, the C6 is a simple mechanical transmission that does not use electronics. First put into production all the way back in 1966, it was finally discontinued from production thirty years later, in 1996. The C6 transmission is rated to handle up to about 475 lb. ft. of torque. Modified C6 automatic transmissions can handle even more. The C6 was taken out of production because it didn’t incorporate an overdrive gear, which would have helped the C6 automatic transmission meet more strict CAFÉ mileage laws. The C6 was used in many Ford products, including the Mercury Cougar, the Mercury Comet, the Mercury Meteor, the Mercury Montego, the Ford LTD II, the Ford Thunderbird and the Ford Mustang. It was also used in the Ford Bronco.

DIY Maintenance: Change the Oil and Filter In Your F150′s AOD Transmission

Posted by on Tuesday, September 9th, 2014

The AOD is a four-speed automatic overdrive transmission built by the Ford Motor Company. It was Ford’s first attempt at building an automatic transmission with an overdrive gear, and lead to the development of the AODE, 4R70W, 4R70E, 4R75W, and 4R75E transmissions. All these transmissions are based lightly on the Ford FMX transmission. The AOD was originally designed to replace the older C4 and C5 three-speed transmissions in an attempt to help vehicles meet new (for the time period) CAFÉ fuel mileage requirements.

If your clients don’t know how to drive a stick properly, offer them these tips to save their manual transmissions.

The history of manual transmission vehicles has been an interesting one in the United States. Since Oldsmobile introduced its automatic transmission back in the 1940s, the number of manual transmission vehicles has been on a steep decline. However, the truth remains that, in many ways, manual transmissions are simply more efficient, and after an interesting uptick in sales since 2012, it is becoming clear that there will always be manual transmissions on the road.

Tips for Keeping the 6HP26 Transmission in Your BMW X5 Running Strong

Posted by on Friday, September 5th, 2014

The 6HP26 is a six speed automatic transmission made for BMW by the ZF Friedrichshafen AG Company. It uses a special planetary gear set that can provide more gear ratios while making the transmission lighter than its predecessor — a five-speed transmission. This transmission is used mainly in high-end luxury vehicles, but it has recently found its way into some not so high-end luxury vehicles such as the Hyundai Genesis. Rated for use in motors that put out as much as 440 Ft Lbs of torque, it is a fairly heavy duty transmission. The 6HP26 comes with a very steep first gear ratio of 4.17:1, which is great for quick jack rabbit starts. It also comes with a 0.69:1 ratio overdrive gear, which helps the car it’s used in get better gas mileage as well.  First put into production in 2001, this transmission is still being produced today.  The 6HP26 can be found in a wide variety of vehicles, including the Jaguar XKR, the Jaguar XJ, the Ranger Rover, the Rolls Royce Phantom, the BMW 5 series, the BMW 3 series, the Maserati Quattroporte, the Kia Mohave, and finally, the BMW X5.

Why You Should Choose a Continuously Variable Transmission

Posted by on Wednesday, September 3rd, 2014

CVT (Wiki)

There are good reasons to consider a continuously variable transmission.

A car with a continuously variable transmission may be a little intimidating at first glance, but as with so many things in the automotive world, it proves itself to be a fantastic idea with a little bit of research. A continuously variable transmission, also known as a CVT, is a transmission that rotates more or less seamlessly through various gear ratios, unlike a transmission that only allows you to take advantage of a limited number of gear ratios. Though it can take some time to get used to a CVT, the advantages make it well worth it.
