Hey, I've fairly recently sold my MK2 Valver for a 1.8 Auto MK3.

Thanks to the other half.

Anyway, having a bit of trouble. It kept not going into reverse or 1st and then all of a sudden it would jump into gear.
Today however it pulled away really slowly, and was doing 5K at 70MPH. I then realized it was stuck in second. If you pull the selector into 1st, it will go into 1st. However, when you push it up, it's supposed to go to at least 3K then change. However it just instantly jumps and really jerks into gear.
I have a feeling it's hopefully just the oil. Would this make sense, it has a bit of trouble getting into reverse?
Thank you.
