Cranking my car is not a problem but when it changes gears it jerks and after so long when it warms up for just a few minutes it will shift down and have no power. It will be difficult to get up a hill or taking off from a full stop. I have to turn the car off and crank it back up and it will happen again. The engine has been worked on with the pistons being replaced and the O2 sensor was replaced the other day and still the same thing. What could it be?

You need to rent a gauge from an auto parts you may need adapters to do this as well. Fuel pressure should be 56-63 psi activated with a scan tool.

Input speed sensor is on the lower left of engine compartment and the output speed sensor is on the transaxle. See pics it may be awiring issue as well but if it doesn't cure your problem then have atrans guy look at it.
