more tranny woes
« on: August 14, 2006, 03:38:26 AM »

Granddaughter always wanted a Sebring-after a couple of Eclipses and a 3000gt all with tranny problems thats all I needed. She ended up getting a 98 Sebring and guess what?
Yup-bad tranny!Shocker!! Anyway,the first thing I noticed was no speedo or tach working. It would hardly idle.When road testing it shifted fine for about a half mile and then it was likeĀ  putting it in neutral.After cooling a few minutes it moved again a few yards and quit. Fluid is up and VERY clean-no burnt smell at all.Thinking of TPS problem to start with,
probably a few more things as well.What do the solenoid packs and input/output sensors control?
Many thanks!!

Definately start with the TPS for the idle problem. Then check IAC, plugs, wires, etc.

Not sure about the tranny questions, I will do some research.

Oh, and welcome to ASOG!  Grin

Thanks so much guys! I was hoping to hear some good news! The way it shifted the first time I drove it i didn't think the thing was bad-hoping it was an electrical issue. I'll post the results when I get it done-maybe someone else can also learn from this but I Cheesy Smiley Smiley suppose this isn't the first time this problem has been posted.
Thanks again!!

This may seem like a "duh" to you guts, but where are the input/output sensors located? So far all we have is a crappy Chiltons manual. I guess I need to find a service manual-looks like I may be using it a lot!!
Thanks!!!!

Well,replaced input/output speed sensors-no luck at all. Moves when cold then acts like it's slipping when it warms up. Still no speedo-replaced gauge cluster with another one. Now tach works but no speedo. You can hear a clicking sound form the tranny for a couple of seconds after shifting,I assume it's the soleniods.
Thank you to those who helped-I guess it was worth a try.

finding out your trany issues are very difficutlt when your there  and person who can
figure it out, somewhere else,, Looking at your attempts so far I would advise you
to go ahead and drop the trany pan and see what is in their,,,fluid dont hav e to
be burnt to be full of contaminets,,, If a plant breaks or converter breaks, lots of
metal but not burnt clutches,,, If you have a clean pan it sounds like you may have
a solinoid pk bad however first and formost you need the speedo working...rreynold@nemonet.com

Thanks for the reply! Not even sure where to start looking for the speedo prob.I thought it was in the speedo itself so tried another one with no luck. I miss the ol school cable sometimes! I hate to keep bothering people, but what all does the shift solenoid control?
Thanks again!!

to try and simplify what a solinid pk does , the solinoids have voltage all the time,, as
the computor feeds off of several different  sencors it will ground the solinoid on a
as needed basis,, how the solinoid  indirectly shifts the transmission is a transmission
can opperate with line presssures from 60 to over 300 psi,, oveiously a little10 amp
solinoid will not deal with this kind of pressure , however the solinoid in the off
position will bleed oil by   with a 80 thousands hole,, the oil going to the solinoid
is restricted with a 60 thousands hole their for no pressure will build up,, once
the solinoid is activated it shuts down this small bleed hole, pressure builds
up on the back side of the shift valve and makes it stroke forward directing oil to
the clutch pk the computor is calling for....rreynold@nemonet.com
