Dear sir do these 3800 engines made in 2005 have a delay start set-up mine will start up sometime and the next time it will whine and whine before it picks it up is there a fix for this thank you

SOURCE: transmission sometimes shifts hard into next gear.

Typiclly this is caused by a failing Pressure Control Solenoid. Now in some cases, since you are in the 1996 model year you may have a vacuum modulator that controls the shift firmness that can be replaced as it is externally mounted. I dont know how best to describe what it looks like, but look down on your transmission, on the front side facing the radiator and if you see a canister like device that has a vacuum line running to it, that is the vacuum modulator and you could start by replacing that and see if it helps.

If you do not have the vacuum modulator and have instead the electronically controlled version of your transmission then you will have a Pressure Control Solenoid and it, unfortunately, is located on the inside of the transmission and cannot be easily replaced without dropping the whole transmission.

The pressure control solenoid is a common issue with your transmission (4T65) and Im leaning more towards you have the electronically controlled version (4T65E).

I seen this before first of all don't let the car dealer to BS the way to your money, most of the time is noting wrong whit the sensor it self but is the plug than goes in to the sensor this what i recommend is to buy another sensor from your local auto part store or salvage yard (cheaper) get three pieces of cable and solder directly in to the sensor brake the plastic around the sensor plug if necessary and secure the three cables to it put some silicon in between the solder and the place the new sensor on top of the old one so you now wish wire goes to which and cut and attach one by one. I now this works 100% i have done it my self many times if you need diagrams or sensor locations you can find that at www.alldatadiy.com now if you still have problems unplug all harness especially all the ones than comes from the back of the engine because that engine tends to leak oil on top of the harness if you have wires doing shortcut replace that section you can solder use heat string tube and change the insulation hose they sale those on part stores to put some zip tides on the ends and you will have your car back and will last Note don't let it get to close to the exhaust use zip tides to keep from touching hot areas.

CPS - Crankshaft Position Sensor; common problem.

I would check the flywheel for missing teeth or looseness. Also check starter itself.

SOURCE: Hard starting when cold ( engine cranks normally )

see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary
