My wife was driving on the interstate when the transmission failed and would no longer propel the vehicle. I have researched the problem and multiple people have had the same problem. I don't understand why no recall has been made. This is a very hazardous issue, especially if you are traveling on an interstate. She had to coast the car over and was rapidly loosing speed, a very dangerous situation. The problem is a faulty part in the transmission called a wave spring. In every f4a51 mitsubishi transmission, this has been an issue. The wave spring breaks, bypasses the filter, enters the pump gears and breaks the pump, ending in transmission failure. It is a costly repair, $1800-$2000. It is a faulty design, and a better aftermarket wave spring was eventually engineered. This should be a recall.

Cpsc#i11b0131a. 2004 mitsubishi diamante. F4a51 automatic transmission failure. *ln the consumer stated she has concerns with the safety and reliability of mitsubishi and dodge vehicles and their owners that have the mitsubishi f4a51 automatic transmission in certain make/models. The main issues seemed to be a manufacturing defect in the wave/cushion spring located in the transmission designed the wave spring as a fragile two coil piece which has been known to repeatedly break causing catastrophic failure in the transmission. When the wave breaks, actual pieces of the wave spring make it through mitsubishi's also faulty transmission filter and lodge themselves in the pump gear,causing the hear to actually break. After the pump gear has been broken inside the transmission, all forward and reverse gears immediately stop functioning and in most instances the vehicle shuts off. The consumer stated she had the f4a51 automatic transmission in her vehicle, which had to be replaced.

I have a 2001 mitsubishi diamante, and am having problems that seem to run rampant among this model/make. My heater core went out at about 100k miles; my ABS light stays on (due to a speed sensor fail), which renders the whole anti-lock system useless; and now my antenna mast is broken. All of these problems are pricey to fix, and most diamante users I have found experience at least a few of these conflicts. Another problem I have seen many comments about is transmission failure at 113k miles. My car has exactly that. On top of everything, it is winter, and anti-lock brakes are much preferred in icy weather. I am starting to smell antifreeze again, the warning sign to a failing heater core, which can leak onto a transmission computer and cause it to fail as well. I am beginning to worry about being stranded, and even being safe in my car. I know I am not the only one complaining, because I have been online all day reading forums from people with similar issues (see the following: http://www.carsurvey.org/reviews/mitsubishi/diamante/r76426/comments/page-5/). Something must be done!

Tl*the contact owns a 2002 mitsubishi diamante. While driving 37 MPH, the vehicle jerked and the service engine warning indicator light illuminated. The contact attempted to accelerate and pull off the road, but when the engine revved, the vehicle moved approximately three feet and stopped. The vehicle had experienced this failure on two occasions. The dealer replaced the transmission at 20,000 miles. The contact also stated that the windshield was severely fogged. The dealer replaced the heater core because it was leaking antifreeze into the cooling system. The driver was nauseated for two weeks. The VIN was unknown. The current and failure mileages were 80,000.

I purchased a used mitsubishi diamante in october 2003 with 52,000 miles on it. A couple of months later there was a strong odor coming from the vents and the window started fogging up. The transmission started acting strange so I took it back to the dealer and was told that the heater core was leaking and had leaked on the transmissions computer. They told me they could replace the transmission computer under warranty but the heater core was not covered and it would cost me about $668. I had to come up with the money to get the heater core fixed before the could fix the transmission problem. I also noticed smoke coming out of the vents early in the morning and the passenger side mats were also soaked with antifreeze.
