So my ISF out of nowhere now just starts wanting to not downshift by it self in paddle shift mode. This only happens when these lights come on the ABS, BRAKE, and TRAC light(shown in pictures).
before then when those lights came on the car would still downshift by itself automatically in paddle shift mode but yesterday when I took the car out it started to act up. I came to a complete stop and didn’t notice that the display still showed that I was in 8th gear so when the light turned green I went and it felt like my car had no power at all then I looked at the cluster and noticed I was some how starting off in 8th gear which is really odd to me cause I’ve never seen this happen in my ISF, my uncle ISF and RCF or my dad RCF.

I did replace the passenger rear ABS wheel speed sensor. Could that be the reason why? But still when I first bought the car I was already seeing those lights come on so to remove them I just simply turned off the car and turned it back on and everything went away. Btw now the light only comes on when the car is really hot say for instance I take the car out for more than 30min and I drive it hard in paddle shift mode with sport on, that is when those lights come on. My transmission still shifts butter smooth and doesn’t not grind what so ever. Any tips?

 

Your have a fault code that is causing your car to go into limp mode.

You need an phone/tablet app like "Torque" or "OBD Fusion" and an OBD Dongle to connect to the car and your app to determine what the fault code is.

If I remember correctly the car starts in second gear and will only go to sixth gear.

I have an "OBDLink MX+" I use.
