Possible limp mode?

DinoJ

This is very strange it's never happened before and i'm worried it could be something serious.

Today I was driving for about 20 minutes casually, not speeding or anything strenuous. It started raining very heavily and I had to stop the car when I got home, get out and put some things in the boot of the car from the garage. I left the car running while I did this (maybe 3 minutes) and then I got back in and began to drive away.

As soon as I got onto the road and tried to put it into 2nd the car started jolting very hard back and forth, same with 3rd, and 4th. I realised it was happening any time I took it to around 3k RPM. Engine temp was fine, (below 220).

So I managed to get home anyway and it's sitting outside now, i'm waiting for it to stop raining before I go check it out.

Is this limp mode? or something else? I did do some strenuous driving last night for about an hour or so on the track but I didnt get limp mode, drove it home fine, it drove fine today, and the temp last night didnt go over like 225 ish.

Any ideas??
