he says it drives but at random times the rpms jump to 4500 and go to 2200 and stay in 4th gear. and stays at a low speed
when he turns it off and opens the door and stats it again its back to normal unitll it acts up again.
we replaced the nsbu and it still acted up.
then we fill it wil new oil when its been running for 3 mins and the level is half way in the hot area. is that normal?
