From time to time when I start out the transmission feels like it is in 2nd gear. Engine labors to get truck moving. Truck has 154K miles. Transmission fluid been changed 10,000 miles ago, give or take. Soon after this slow start up the check engine light comes on. After a few miles it starts to shift normally again. Check engine light goes off soon after that. Right now it is working fine. Something else it does is f transmission dip stick keeps rising up in holder. I have to push it back down every time I lift hood. It has basically been doing this since I got it 12K miles ago. Hoping someone here has insight on this situation. Electrical issue, or inside transmission? .
