Upgraded 5L40E parts: Yes: Performance shift kit, valve body improver kit, and more. The 5L40E was replaced in 2007 with the 6L50 six speed transmission. Before we get into the faults and foibles, I thought I'd include a little bit of background information on this transmission. Smart Parts Automotive© official site. One of these awards was the Better Business Bureau National Torch Award for Market Place Ethics presented in Washington D. Upgrades Some transmissions have inherent factory flaws causing them to chronically break down. This causes the wire to internally short out and by doing so shorten the path that the electricity must take.
Even though the 5L40E was used in high performance luxury vehicles it was known to have a few inherent problems. From its performance built lock up torque converter to the state of the art solenoids and valve bodies, you can rest assured that this will be the last 5L40E transmission your vehicle ever needs. We do not charge restocking or shipping fees when a transmission qualifies for a warranty. It was underrated when used in combination of M57D30 engines. Buying a used 5L40E transmission may save you money. When that oil heats up and thins out, it can start finding its way out of these worn seals and valves, causing a lack of pressure when applying a clutch.
Even though the 5L40E was used in high performance luxury vehicles it was known to have a few inherent problems. Call Monday-Friday 9-5 Central 1-888-995-7278 Dyno-Tested Every transmission has been run on a state of the art Dyno. The 5L40-E had been designed for 1. The electrical system, sensors, solenoids and thin coated wires are a common failure point. The electrical system, sensors, solenoids and thin coated wires are a common failure point. Can you please tell me what is the problem with this sort of car and what should I do.
Solenoids, in the simplest description, are nothing more than electric magnets that move a plunger. The 5L40E unit's centerpiece is an automatic which supersedes the French-made 4L30E four-speed automatic light-duty gearboxes, and like them features a clutch to eliminate slipping losses in select forward ranges. Sensors could send faulty codes and the computer could respond with error codes. When those seals start to wear, transmission fluid can escape, lowering the pressure. They are used to move the valves in the valve body and control other functions within the transmission, such as the line pressure and torque converter lock up clutch features. Our technicians have an average experience of 10 years or more.
The 5L40E torque converter is included with every transmission. This article needs additional citations for. The easiest way to check for this problem is to remove the sump and check for debris. If a decision has to be made to replace the transmission, I highly recommend you consider a as your first choice. They differ from a rebuilt transmission in the fact that they are as good as a new transmission at a greatly reduced price and often include modifications and upgrades that make them much more durable.
The accumulators work by sitting a small sealed piston on top of a spring so that when the oil is fed into the chamber, it pushes the piston against the spring. This not only causes the oil level to rise, it also causes it to become thinner. Warranties for a used transmission is only 30 days, 60 days, 90 days or 6 months. The 5L40-E had been designed for 1. The debris circulates throughout the transmission and, eventually, begins blocking the filter. Erratic shift patterns, overheating and speedometer calibration have all frustrated users of the 5L40E for decades.
No one wants to pull a transmission more than one time. In cases where a transmission is worn but not completely gone, it may drive fine when the oil is cold and viscous. My inquiry is what parts will I buy when a total transmission oil and service should be done. Erratic shift patterns, overheating and speedometer calibration have all frustrated users of the 5L40E for decades. The 5L50 can handle up to 311 ft·lbf 422 N·m of torque. Failure to address this problem once it evolves could lead to the total failure of the transmission.
A Dyno simulates the conditions encountered by a transmission during every day and extreme use. The 5L40E unit's centerpiece is an automatic overdrive which supersedes the French-made 4L30E four-speed automatic light-duty gearboxes, and like them features a torque converter clutch to eliminate slipping losses in select forward ranges. I've also included a nice video overview below. The additional cost may be higher than installing a reman or rebuilt transmission--not to mention the extra downtime. We will let you know if we do. Please be aware that this article assumes some but not a lot of working knowledge of cars and terminology.
