1987 N/A automatic

ok i had my starter go out last week replace the battery bigger one at that and today finally got a used starter back in there. now the car started right away, but ones i started driving i noticed the overdrive button not working. push it in and the rpms dont drop. at no speed can i disingage it. i didtn have those problems before last week.

would having a 5 sp starter do that? i got the starter from the junk jard but did specify for automatic. like i said she runs great execpt the car is stuck in overdrive. stays in low rpms at all times. like then you hit the button. i looked at the wried under the shifter they all seem to be in tackt. looked inthe haynes manuel but nothing about it in there that i saw.

anyone have any suggestions. i dont know where there would ba any fuses for this or more to check. i did a search but there was only one write up and it was a completely diff artice.not the same problem.

please help.

thanks

one more thought , we alos put the car in neutral to move it to a differnt spot i didtn know if us pushing the car back and then forward could hurt anything .

also tonight while driving it i noticed after driving it about say 30 min my buzzer came on, no lights just the buzzer. the coolent buzzer that is but no light.

any thoughts ? i guess ill check my fluids tomrrow all of them but still need help on the hole overdrive being stuck that is it feels like it nothing happens when i hit the button.

I would not think the starter would be related to the computer and transmission very directly.

When you enable/disable overdrive lockup you still have to give the car a reason to shift... aka if you are accelerating hard it will shift into od later to get the most acceleration.... and if you're in over drive and adding gas letting it shift (letting off the gas) would not hurt for going down, u'd also want to decelerate to avoild braking.

Pushing the car slightly should not have affected anything.

ive never even seen a automatic rx7 so i dont know how they work , but if your od button isnt working .. is there a soleniod that controls the od? or possible something that connects to the outside of the tranny that you might have jarred loose or hit accidently when swapping out the starts?? like a harness or something?? just a shot in the dark !?!?!

no really sure what exactly your trying to say but i did get you saying the starter has nothing to do with it and us puching the car has nothing to do with it. before the starter went out hte car was fine i could drive hit the overdrive button and hte car rpms would drp and the car would get quiter. now the for some reason i can hit the swith and nothing happens at all at any speed. sucks cause i can drive try and accelarate and the car shifts at 4 rpms.

would low tranny fluid do this ? i dont think it would but it was worth a though
please help anyone ?

Low tranny fluid might cause hesitation in adjustment but overall shouldn't prevent overdrive.

I was trying to say that while driving and switching overdrive on and off you have to allow for the transmission to want to shift. If you are accelerating fast in a car you will notice that it will not shift up until u let off the trottle -- similar to shifting in a manual. If you get into overdrive then to get out you will need to slow down so that the engine can keep up with the wheels or else the shift may hesitate or not happen.

Something like this could just be a faulty button, so you may want to check that if convenient (ohm meter).

I didn't think a 5 speed starter would work considering a flexplate is bigger in diameter than a N/A flywheel. You may have lost overdrive all together. Check your tranny fluid and if its brown adn muddy your clutch discs are burnt and you can start kissing the other gears goodbye. I lost 3rd and overdrive overnight when I had my auto.

i will check all the fluid this morning. just kind o weird that all of a sutton the its in overdrive at alltimes. like i said didnt do that before. nor did i drive it hard ones i started the car again. is there a certaing setting i should be looking at under the car at the tranny to make sure its set right?
let me know thanks again

i had the car up in the air , looked underneath at the tranny , i noticed on the driver side , by the tranny close the pan, there where three ereas going into the tranny, one of them looked like a part you can turn like a dial i believe when looking at it fro mthe below ythe far left one, had one cable going to it a black one with i belive a white stripe too, it was cut in 3 places really close to gether, now it was still in tackt but the insulation part was cut. couldthis be the problem? i was going to change the wire but am not sure what guage the wire is . someone please help

also is it bad for me to drive around in overdrive at all times? please let me know
thanks

Overdrive saves gas, its 4th gear, you should drive around at all times in it unless you want quick throttle response under 40. There are two screws on the automatic handle. Take those out and pull the handle off. Check to see if your prong that goes between the sensor and button are connected all the way or dirty. Try cleaning it and put it back together. Also pull off the surround and check to see if the connection from the shifter to the powersource are making full contact.

the botton has one screw and the button comes out has two wires to it the rest of the wires feen back in the shifter. so where exactly should i check the connections. im going to get a volt metter tomrrow and see if im getting power there . if not what should i be checking next.

well im all about saving gas but i do like having accelaration of a stop or roll .

anymore advice ?
thanks to all
