2264, Only have second gear?!?!?
Posted by discount_tyr420a, Nov-19-03 12:16 AM
just cruisin along and it justed dropped into second and didnt come back to anything else. i've read that you guys have had teh problem b4 on a couple posts and said it was the input sensor. it does come back for a lil while tho when i stop the car and turn it back on. after a few min tho it just only has second again....any sugestions? or did you try the sensor replacement and have it work?

The car going into 2nd isnt your problem. It is just in what you call safe mode or limp home mode.

This can be a good thing or a bad thing. When it goes into safe mode it can hinder further damage. But, it doesnt allow you to "feel" for the problem.

There are scanners that can pin point your problem, of you can go replacing sensors. The IP OP would be my first choice. If that doesnt help drop the pan and check out your magnet.

thats cool...would changing the tranny fluid and filter help me at all, cuz i'll prolly just do that while im at it too. oh...and how hard are those sensors to change?

Like replacing spark plugs essentially.

Changing the fluid out wont necassarily fix anything because the computer has gone into safe mode. Have to reset the computer to do that. txchange.com has those sensors really cheap for our tranny. check em out.

It'd be a good idea to drop the pan though to see what's going on inside.

Limp to autozone and have the codes pulled, then replace the part that it says is bad.

Thats why we have a check engine light and obd2 diagnostics so you dont have to just start changing stuff.

the only prob with the CEL is that i dont have one on, or never did. but the car has 186k on it so im thik that sensors can go bad after that much

just because the cel isnt on doesnt mean there isnt a code stored for the problem.
is your speedo working?
2277, RE: Only have second gear?!?!?

yeah....my speedo is workin just fine. and where is the sensor located exactly. cuz i want to see whats up woith it before i start rippin sh** apart

They're in the front of the trans. Ones on the inner and one on the outer.

download the F4AC1/A604 overhaul and you'll see em.

actually they can pull obdII off my car....xtremeRS dores is with mine all the time, but im gonna try the sensors first, i was readin another post tho....and he had a good question, what makes those sensors go out? cuz mine just cut out when i made it shift down so i could pass someone.

sometimes the head of the sensor just wears out and gets chopped up in the trans.
its just like any other sensor though, time/heat/weather/friction all cause a sensor to go

and yes you can pull the codes from a 95
and actually the keydance works on my car which is a 98 (made in 98)
it only works on avengers/sebrings though, not sure why mitsu disabled it or whatever for the eclipses

hmm, my 98 wont keydance, and i cant read codes with a pocketlogger.

mike at PL needs the a/t wiring schematics to figure out cel code readings through the software.

i had that problem on my 99 "2gnt" gs. Automatic. I took it into the mits dealership and it ended up being the throttle sensor. Does your Speedometer not work also? i had that problem on top of it all also. You may want to check that sensor. Ive heard its pretty hard to get to so you may want to just have it checked by the dealerships. Cost me about 200 bucks. (maybe a little less.) :+

more mods to come!!!!

when your speedo stops working and the car goes into limp mode its the output speed sensor, cost about 35 bucks time to install is about 5 minutes. TPS can cause limp mode and is usually associated with hard shifting and bucking in limp mode. cause the ECU has no idea of throttle position and goes off the map sensor
