Why Did My Transmission Fail?

Automatic Transmission Confusion.

Automatic Transmission Confusion.

Of the automatic transmissions that fail, over 88% failed due to design flaws. These are failures that were not caused by abuse, misuse, lack of maintenance, or excessive mileage. Hard to imagine.

A design flaw is characterized by a repeated failure in a specific area in any one type of transmission. Many products and upgrades are available from the vehicle manufacturer and in the aftermarket to alleviate these problems. Correcting the root cause of failure gives GotTransmissions.com has the ability to provide long-term warranties.

Most Common Transmission Flaws

Chevy and GM sport utility vehicles such as the Tahoe and Yukon come in quite often. The combination of high torque and considerable weight exposes a manufacturing flaw in the sun gear shell. When the shell breaks, the most noticeable symptom is no reverse.

The Ford Windstar shares the same transmission as the Taurus and its sisters, the Sable and Continental. The worn shafts that fail are from a Windstar, and the damage is caused by a poorly designed bearing, which rides on the shaft. We install an upgraded bearing that alleviates this problem.

Honda and Acura vehicles have a unique design that does not utilize planetary gears. This design places a limitation on the maximum diameter of the friction plates. An increase in force against the plates is necessary for proper operation, and this leads to premature wear.

Mercedes Benz produces a 5 speed automatic that is fully electronically controlled. Most transmission problems in these cars are electrical, commonly the conductor plate above the valve body, which can be accessed without removing the transmission. Other electrical problems include fluid getting into the processor, and rain or beverage getting into the gear shifter.

In the eighties and nineties, Toyota and Lexus had the most reliable transmissions of the major car companies, but that has changed. The new automatic 5 speed transmissions in the Toyota Camry and Highlander, as well as the Lexus RX300 have proven very unreliable.

Expensive remanufactured transmissions can be purchased from the Toyota Dealer, but they only carry a 1 year warranty. These units don’t address the planetary gear carrier design flaw, so the problem is destined to reoccur. GotTransmissions.com welds the carrier to correct this problem, and can provide an extended length warranty for peace of mind.

Cadillacs such as the Deville and Seville with the Northstar engine, have an internal input speed sensor and a viscous torque converter that are both prone to failure. The location of the sensor requires removal and partial disassembly of the transmission to replace it. While torque converter replacement only requires transmission removal, there are related seals that occasionally contribute to its failure, which should be replaced at the same time.
