You could probably do a world of good by replacing the transmission fluid. The fluid may of never been changed before and possibly some dirt got into your vacuum modulator ( or throttle cable linkage to the transmission). The modulator takes signals from the load on your engine and tells the transmission when to shift. If that modulator or whatever sensor is used on your particular car gets worn out or loses it's vacuum seal then the transmission will not get the proper signal when to change gears.

You might want to go on to YouTube and see if there is a repair video for your GM car. Seeing how it is a 1988 it probably still uses engine vacuum hoses to control the transmission shifting.

I have a 88 Plymouth horizon was running fine And all of a sudden I turned the key on and nothing happened I changed the battery new ignition relay and still nothing can anyone tell where to find wiring...

Try holding key in start position while moving shifter slowly through all gears to see if you get a click or start at all. Safety neutral switch/back-up lights on transmission were known to cause that problem.

88 bronco 2 automatic v6 will sometimes not go in any gear but if I'm lucky it will kick in and go can anyone tell me the problem

the problem was changing that fluid! rarely happen, but it will happen when people change transmission fluid on older car then the car messed up. when you change the fluid you washed all the friction material on the clutch surface by putting in new fluid.

1997 olds 88 transmission problem

Hard to say, it needs to be taken to a transmission shop so they can do a diagnostic test on it.
Could be the torque converter lock-up switch,
the servo pump in the tranny
one or two of the solenoids in the tranny
or just a plain old filter and fluid change.

This is a common problem on some GM cars. There is a pressure control valve in the side cover of the transmission that needs to be replaced. The transmission does not have to be rebuilt. You will need to get a side cover gasket also.

Lights not working well

mine does it too i think they all do after time it's actually a non-replacable bulb. you have to replace the whole cluster once you pull the the dash apart its one plug and four screws. or you can knock on it in the area where it tells you the gears and miles and it will light up (like your knocking on a door)
