StepSpeed

I'm having a problem with my stepspeed gearbox.
I can only select 1 and 2nd gear.
Is I put it in Sports mode it will allow me to toggle between 1st and 2nd gear.
P, R, N, D doesn't show up on the display. The orange gearbox warning light comes on. If I put it into Sports mode the warning light goes off and I can select 1 or 2nd gear. Once I put it in normal mode the warning light comes back on.
When driving it limited to 3500rpm. *

I don't know much about the stepseed except it likes to have decent fresh fluid.

It might be worth plugging in a scanner to see if there are any fault codes.

Let us know how you get on.

Hi,
Underneath gear selector there is a switch giving the electrical signal to both your ECU but also depicted in the dash. The 3500rpm limitation is that you go under safe mode and it goes off for some secs upon you restart the engine.
I believe the root cause is on this switch. Try to clean it initially with a dedicated spray without oil and give it a try. If it is ok then you need to replace it as it will not last much. Hope this helps
