Volvo Vida Gear Shift Indicator Mode
 

Warning: this is a very boring video. But it may help you to diagnose a torque converter fault on your Volvo with TF80SC transmission. I had no problems but just wanted to know what the function in VIDA did.

I made this video as I had been wondering for years what it did. So here you go if you are also wondering.

Its very boring.
