    Two trucks with similar problems. Are you refueling them at the same place? It sound like bad or water in your gasoline for starters. Possibly debris that has clogged the filters. That's were I would look first.

Sounds like one of the ignition coils might be bad.

Depends in the mileage since the transmission was last serviced. It sounds like low pressure from the pump. It could be just a filter. You did not say where the leaking seal is, but a leaking seal will not fix itself.

04 nissan sentra shifting hard


Do you have a CVT? (Continuosly Variable Transmission) I doubt that you do so if you dont, nissans are known to have hard shift into second gear you mean.(Once the car moves, its already in first gear) so if it shifts fine into other gears, I wouldnt worry too much unless it gets worse.

It sounds like a tork conveter lockup switch, have the transmisson serviced oil and filter changed then and add Lucas transmisson treatment to help smooth out hte shifting pattern and stop the problem if there was drag on the clutches it may have stalled out.

04 f150 jerking going uphill


Ignition timing would be #1 on the list. Also check your plug wires, or change them. Check your air filter, and change the fuel filter. It could also be your egr system, faulty ignition coil, or a vacuum leak at the intake manifold.

Jerks going into 3rd Gear


more than likely you will need a valve body rebuild. you are probably looking around $500+. don't let them try to sell you a transmission. you could search ebay and see if you can find a "rebuilt valve body" but make sure it is for a '00 to '02 SL2
