Can I replace a head gasket myself? Head gasket replacement is not a job for the average do-it-yourselfer. While a head gasket expiring due to old age is rare, it usually means everything else is worn out to the point of replacement as well. Cracking the head off the engine and peering inside may reveal that everything else got fully cooked, too. https://www.google.com/search?q=2001+oldsmobile+alero+replace+head+gasket and here for head gasket and cylinder head bolts https://www.google.com/search?q=2001+oldsmobile+alero+head+gasket+replacement If you have a leak or crack , you might consider this fix.

Injector clogged , plug fouled, weak coil , bad plug wire if not coil on plug , weak compression on that cylinder from bad rings, valve seat or head gasket .

remove and clean all cables and the battery itself,bad connection somewhere

No , clogged fuel filter would cause problems at higher speed , lack of power . What engine does it have ? 2.4 or 3.4 You have a sensor problem , maybe . If your vehicle has the 3.4 L V-6 it has two crankshaft position sensors A & B One is for low speed operation & one for higher speeds . I would think the 7X is bad . The 7X CKP sensor is bolted into the center of the engine block and protrudes into the crankcase. The 7X CKP sensor reluctor wheel is cast into the crankshaft. The 7X CKP sensor is a variable reluctance sensor. The magnetic field of the sensor is altered by a reluctor wheel that has seven machined slots, six of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees from one of the other slots. The 7X CKP sensor produces six pulses and one sync pulse for each revolution of the crankshaft. This signal must be present for the IC module to send a 3X reference signal to the PCM. The 3X reference is known as the low resolution engine speed signal. This sensor is located in the side of the block . The 24X crankshaft position (CKP) sensor (1), secured in a mounting bracket (3) and bolted to the front side of the engine timing chain cover (2), is partially behind the crankshaft balancer. The crankshaft balancer contains the 24X CKP sensor interrupter ring. The 24X CKP sensor contains a hall-effect switch. A hall-effect switch is a solid state switching device, which produces an OFF-ON pulse when a rotating element passes between the sensor tip and a magnet. This rotating element is called an interrupter ring. In this case the interrupter ring has 24 evenly spaced blades and windows. This sensor produces 24 ON-OFF signal pulses per crankshaft revolution. The 24X signal is used for enhanced smoothness and idle stability at a lower calibrated RPM. The 24X signal is known as the medium resolution engine speed signal.

Unfortunately you now probably have a sticking solenoid in the transmission, but you also may have an oil pump problem in the transmission. These are expensive repairs, so I would try having the transmission oil replaced and perhaps adding an additive recommended for this.

probably made a harness connection to the fuel pump come apart in the fitting the new transmission
