Probably every transmission repair specialist was keen on LEGO constructions or at least enjoyed making some minor things with their hands. Here's the game taken to a new level of creativity!

Modern auto industry is full of sophisticated drivetrain technologies which are supposed to make your driving experience even more pleasant and trouble-free. Despite a great abundance of sophisticated technical solutions, it is highly likely that very few people know a transmission solution operating like a manual CVT.

Over recent years engineers developed a lot of gear shifting solutions for different car brands, which may seem a bit unusual for oldtime drivers. In this article we will review the most peculiar gear stick technologies and provide video materials related to these technologies.

Only few people know about transmission concepts which were popular 70-90 years ago. For men of today, these gearboxes may seem very unusual and weird, but even now some gearboxes that date back to those years are quite competitive in comparison with modern transmissions.

Nowadays Extroid CVTs are commonly known as “toroidal” due to the fact that the working surface of driving and driven discs in this transmission has the form of a torus. Extroid CVT is not a V-belt transmission, but a friction drive CVT.

Jeep Renegade and Cherokee Recalled for Fuel Pressure, Transmission Issues


Jeep Renegade and Cherokee Recalled for Fuel Pressure, Transmission Issues

Recently, Jeep, a subsidiary of Fiat Chrysler Automobiles, announced 2 recalls for a pair of its vehicle models, the Jeep Renegade and Jeep Cherokee. The Renegade's recall is caused by a potential loss of fuel pressure, while the Cherokee's transmission calibration could lead to engine stalling.


2018 Jeep Renegade



The Renegade recall includes more than twenty thousand vehicle models released in 2017-18. According to official documents, it's only 5 % of the recalled cars that contain the malfunction. The problem lies in the fact that the loss of fuel pressure takes place in high-altitude driving during "high power demand" instances. This can lead to the engine stalling, which enhances the probability of a road accident. The engine may still operate and a caution light will be displayed on the dashboard. According to official documents, the solution for the abovementioned defect will not be solely limited to software update. Engineers still work on development of a replacement fuel-delivery module which will help to fix the problem. Owners of affected cars will start receiving notifications in early December.



2019 Jeep Cherokee


The Jeep’s Cherokee recall will include 86,053 cars belonging to the 2019 model year equipped with the 2.4-liter inline-4 engine. According to Jeep officials, defected cars have a transmission calibration that will not operate correctly when a driver eases off on the accelerator. As a result, the engine may stall if the software doesn’t operate properly.


This problem increases the chance of a road accident; however, there is no official information about any collisions or injuries associated with the problem. This defect was detected and eliminated on the line, so cars produced after Oct. 16, 2018 are trouble-free.

This transmission issue can be fixed with the help of the software update that also will prevent the possibility of stalling. Owners of defected cars will be informed no earlier than Dec. 8 – this is when Jeep plans to start the recall campaign.
