Speedkar99 brings you videos on automotive repair and the reverse engineering of car parts. The aim of this channel is to present clear, concise and easy to understand information to arm those who aren't familiar with an automotive subject with enough knowledge to understand how it works or take on a DIY repair task at home. The approach is balanced between some explanation of engineering theory and with hands-on tutorials. This gives the audience a broad overview of how components fit and work together in a subsystem, technical knowledge and provide pointers on repairing your car and saving money. Knowledge is power, and by sharing this knowledge we can all learn, discuss and benefit. Enjoy!

Video Description

Here’s a look inside a Nissan Continuously variable transmission and how it works! Nissan CVT’s are notorious for failure, with multiple warranty claims, recalls and lawsuits supporting there was design and manufacturing negligence when bringing it to mass market vehicles. The transmission torn down in this video was from a 2012 Nissan Altima with 160,000km. It suffered from the variator pins shearing from the shaft and piston seal damage. This would cause the transmission to slip, as the variator can no longer hold pressure against the CVT belt. A lot of debris and metallic paste was found throughout the transmission. Further failure points on Nissan CVT’s are belt failure, forward and reverse clutch failure, oil pumps, and valve body server motors. By far the most common is an overheating transmission due to an under-designed cooling system. It is recommended to add an external transmission cooler and change the fluid frequently to extend the CVT life.
