Not necessarily terminal, would be best to have the codes read to see what is listed.
Battery could be old or just needing a a proper overnight charge.
Faulty wheel sensor can have an effect on the Gearbox.
Gearbox might be requiring service and reflash.
Car details would help greatly. I'll move this to its own thread as its a different problem to original poster.

Hi Doug When you say wheel sensors I take it you mean ABS sensors. I know if you get a fault on these it can put the engine into limp mode but I've not heard of a fault on the gearbox. But it's always handy to know for future reference
