limp but no code after winter

[dalplex 1]

My 450 was nothing wrong before winter but developed some laziness after 3 month. From what I noticed of symptoms. It is in limp mode. However, there is no code.

Whai should do after trying to lub the wastegate?

Thanks

It could be a fault with the transmission, which will not light up the check engine light.

It does not shift up to 5/6 although manually can be done. In those case, rpm did not lower.

It is annoying as some time can not engaged to gear at intersection for green light. The car just not moving and rpm not going up too much neither.

I could drive it on 100 kmh with pedal on floor but rpm seldem pass 3000.

All in all make me suspect it is on limp mode.

My car was doing the same thing. Ended up being the Transmission sensor needed replaced. The rebuilt transmission that had been put in my car 1 month prior wasn't able to register the gear changes, especially 6th gear.
