Jettadan1 :

Welcome to JA. We are working on a fast accurate answer. Your valuable time is very important to me. But a great answer has to well thought out. The exhaust leak is seprate from the traction control

Jettadan1 :

most likely you have a bad speed sensor.

Jettadan1 :

but to find out which one it is you have to have the hhr's abs traction control module scanned.

Jettadan1 :

and this will tell you if its is a speed sensor and which wheel it is coming from or if it is a more serious issue.

Customer:

what is the sensor on the back side of the transmission

Jettadan1 :

there are out put speed sensors and other sensors back there.

Jettadan1 :

but your traction would be read from wheels

Jettadan1 :

the one on the tranny is for tach and speedo and such

Customer:

there is oil residue on the left side of tranny. could this affect sensor

Jettadan1 :

No

Jettadan1 :

a little is normal.

Jettadan1 :

as long as its not dripping

Customer:

what causes this problem

Jettadan1 :

if it gets on one of the electrical connections it can cause false readings

Jettadan1 :

it can be dirt in the rotor or a loose connection to sensor or a bad sensor its self.

Customer:

can the sensors be cleaned

Jettadan1 :

it has to read all the spaces in the rotor and its magnetic. and every time a metal piece goes by it it reads it and compares it to other wheels readings and if there is a difference then it will stop it from spinning

Jettadan1 :

yes they can if thats the issue

Jettadan1 :

you can use electrical cleaner and compressed air and they will clean right up if would be good to get rust out of rotors also and that messy

Jettadan1 :

I use compressed air and spray it and run away lol

Jettadan1 :

once the cloud of rust dust goes down i go back

Customer:

would this cause trans to shift hard when tc light is on

Jettadan1 :

if oil is in connection on tranny and maybe if speed sensors on wheels had issues yes.
