you might be loosing a gear or a wheel baring, it could be a lot of tings
The following are the ratios for an 86. I believe they changed with the 88.5 model. Gear ratios 1st 3.652 2nd 1.947 3rd 1.423 4th 1.000 5th 0.795 Reverse 3.466 Hope this helps.
It depends on the gearing of the car. If you are in the highest gear and 40mph in that gear is under the idle rpm of that car than you will stall.
To change the CVT gear oil in Suzuki Swift, you need a 4L can for your car.
