How does a Mini Auto Tranny act.

Ok I am working on this Mini Cooper it has 84k on it and when you mash on the gas it takes a whiles to pick up some steam. It hoovers around 5-6k rpm's and acts as if it is slipping. Its very strange because when i do that I can't even feel it shift but it does. Is this normal or is the tranny getting ready to go out the door.

Specs on the car: 05 Cooper NON S Auto Tranny

is it a CVT tranny

Just looked it up, it is a CVT, :lol


The base car is powered by a 1.6-liter inline four that makes 115 horsepower. This isn't much power by today's standards, but with only 2,300 pounds of car to propel, it's not dreadfully slow. A five-speed manual transmission is standard, and a continuously variable automatic transmission (CVT) with an automanual mode is optional. The sporty Cooper S is aided by a supercharger, allowing it to pump out 168 hp and 162 lb-ft of torque. A six-speed manual gearbox is standard, with a six-speed automatic optional. For those who need more performance, Mini offers the dealer-installed John Cooper Works package, which increases output to 200 hp and 177 lb-ft of torque.

The 05 MINI Cooper with auto uses a CVT transmission with similated shift points. That is, there are set shift point if you use the manual or paddle shifters. Hence that might explain why you feel definite shifts sometimes.

It does actually accelerate and "pick up steam", but because it is a CVT, it doesn't feel like it.
