Battery power and its effect on the transmission/gears
I just had my 1995 Safari in for service 2 days ago, fixed an intake Manifold coolant leak, replaced gaskets and seals, T-Stat and cleaned out EGR passage. Also did major tune up with spark plugs, wires ,rotor and cleaned throttle body. Now 2 days later the battery is fully discharged, appears not to be charging at all as the gauge does not indicate it was charging just discharging. Battery is 3 years old on a 6 year battery life. The transmission will not shift and engine idle on the vehicle is running fast. Can these some how be related?

I had a 2000 malibu 3.1 and the manifold gasket was leaking. Model years affected, 97-04. Check the recovery coolant tank and if it looks like a milk shake instead of coolant, then you have a bad intake manifold gasket. I replaced mine a few years ago and all was fine. Engines affected are the 2.4-3.1-and 3.5, look very carefully around the intake manifold and you will see it if its leaking! operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks. Because oil will mix with coolant if gasket is bad. Hope this helps you out! Good-Day!
Not very likely, check the coolant passage between the cylinder heads. (The front part of the intake, right behind the alternator) That piece which is part of the intake manifold has been a source of coolant leaks for many vehicles like yours. The alternator is pretty easy to remove... Disconnect the negative battery cable, turn the belt tensoner to remove the belt from the alternator, take out the two long 10mm bolts under the alternator and the three on top. I would check for leaks there because it was a common problem area, coolant would leak behind the alternator, fill the space under the intake manifold, and leak down right where the transmission bell housing is. There are expansion plugs, and allen plugs on the back of the cylinder heads, but they rarely leak.
Oil leaks, coolant leaks. Make sure the oil and coolant inside look good. Make sure oil is not burnt. Check axles on car. Make sure the windows, heat, cool, guages, gears, wipers, lights, washer fluid, cruise, trunk pop, hood pop, brakes, brake lights, turn signals, all work. Check it all. This car is 15 years old. Make sure you test drive it and run it like you are in a race. It is important you do, just in case it has something wrong with it. Best wishes.
These symptoms indicate a vacuum leak. Check all vacuum lines attached to the engine intake manifold--especially any that go to the transmission. Check both ends with the engine running for tight connections and listen for leaks. Also look carefully over the intake manifold for any missing hoses--a port on the manifold that is sucking air. Let me know if you have questions and thanks for using FixYa.
weak battery ,or more likely a bad terminal at the battery . some of these also had a concern with coolant leaking from the intake manifold getting into the cylinders and hydro locking the engine.But check battery terminals first along with the battery
These had a very common problem with the injector assembly inside the intake manifold. They develop leaks around the seals at the base of the injector spider. You can remove the plenum tuning device at the top of the manifold and look in with a flashlight and see how one side of the intake is washed and wet with fuel to confirm this. To fix the problem you'll need to buy a new injector assembly and gaskets for the upper intake assembly as it has to be removed to get at the injectors.
