My car have been making weird noises. today while driving to my parents, it wouldnt pick up speed. if i step on the gas it made really loud noises. it would not reverse too. is it my transmission? do i need a new one?
First check your transmission fluid level improper fluid level is the number one cause of trans failure, you need to check it with the vehicle warmed up, on flat ground, i accidently checked mine while it was tilted in my driveway and i got a false reading on the dipstick. The fluid should have a reddish color too it, if it is light brown, its time to get it serviced, if it is dark brown or black and you can feel gritty particles while rubbin it between your fingers, your transmission is toast.

I do not know if this vehicle has a torque converter lockup or not, but sounds like it. Does the transmission stop shaking when you go over 65? Some vehicles have a torque converter lockup, which means when the vehicle is traveling at a certain speed in high gear the torque converter "locks" and there is no slippage to the transmission resulting in better fuel economy. if the torque converter doesn't "unlock" when you slow down to say 45 then the engine will "lug" causing vibration. If this is the case you are not hurting anything by driving, just shift to 3 when it shakes then upshift under lighter load, or take it to a shop that replaces transmission sensors.
With electronic ignition sytems today there are no moving parts in the top of the ignition module. Spark plugs and an Air filter is about all you can do for a tune up at home. There is no need to do any timing adjustments.
However..... if you have not changed the timing belt on an 8 year old vehicle it is time to have that done. A worn or loose timing belt can cause your vehicle to idle slower or not maintain an even speed when using a cruise control system or (cruise off) driving a contsant speed and the car seems to cycle up and down in speed a little bit.
I have the 1990 model and just so happened to stumble on its unusual location today as I was replacing the door hinges. On the passenger side open the door and look above the step, there should be a little plastic cap with the wiper icon on it. hope this helps!
