Hello there Scotty, when I’m going on the highway and I am growing up a small hill, at about 2500 RPMs the RPMs begin to fluctuate up and down a little bit. By this time I am going about 70 Miles an hour and you can feel the tagging that I will leave the transmission is doing. It only does it Whenever I’m cruising at about 70 to 75 miles an hour and I am climbing. Your thought? 


Mileage?

It's amusing that according to that link Nissan claims they developed "the first CVT for passenger cars" in 2002.

 

The Subaru Justy offered a CVT in 1987. Probably the first modern (postwar) automotive CVT was the DAF Variomatic, introduced in the DAF 600 in 1958.

 

A characteristic of the Variomatic was that it could run as fast in reverse as fast as it could forward. Because of this feature DAF backwards racing was born.

That is hilarious! 😆 I like the part when the pink+yellow car flips over the white one.


Racing improves the breed! Now if you could do that with a Nissan CVT it might have some redeeming value. 😎

Those use a lock up function of the torque converter that can do that to a degree if it’s coming in and out of lock up… otherwise if it’s more of a judder or belt slippage for that age vehicle it should still be under warranty
