Service light stays on

I just got my transmission replaced(rebulit) and the lighf can on after the job was done. so i brought it back and i was told it was an old code for the trans. they reset it. 2 days later and it has come on again. Should this be happening or should i be worried about the rebuild of the trans. i am going to have the codes read at an auto zone to double check the codes.any help will be appreciated. thanks in advance

No the check engine light should not be on. We won't know what the problem involves until you get the codes.
And keep in mind, trouble codes only tell the mechanic what to test, not what to replace.

    do you know if old codes should pop up after the problem is fixed

    On vehicles built after 1995 a trouble code stays in the system until it is erased. But an old code should not turn the warning light on. If the code is there and the light is off, that code should not turn the light back on again.

SOURCE: Service engine code indicates EGR valve.

You could have a restriction in the egr ports. remove the valve. Plug the holes, start engine. 1 hole will be blowing out exhaust, the other will have large vacuum.

SOURCE: p0455 comes back on ,we try to fix it

The EVAP control sytem is checked by the ECM upon the first start of the day when the engine is cool and will trigger the DTC code P0445. If you have a vacuum line leak when it's cold and seals it self when it warms up then the code will stay there. After warming up the car reset the ECM to clear any DTC codes and see if any MILL shows up. IF not then there is a leak only when the system is cold so your going to have to try to do a smoke test when the system is cold.
The other thing is to check all the vacuum lines and fittings around the canister and fuel tank for any lose clamps ECT.
Good luck and keep me posted. Be glad to help you

SOURCE: My check engine light kept coming on and they

Could be a wiring issue, fuel cap got left off, fuel pressure sensor again or loose connection to the sensor and one of the other Evap hoses. Also might try changing the fuel cap. Look at the underside of the fuel cap and if there are cracks in the sealing rubber, replace the cap.

Just had a brake job done. My xc90 2005 has 100000 miles. After the brakes were done and car was picked up, brake light still comes on. Was told not to pay any attention to this, that it would cost 1700.00...

While I can't say for certain a replacment module is or is not in need of relacing, the fact that the brake light stays on would make it difficult for you to sell the car and in most states would fail inspection. Ask whomever told you to ignore the light to put that in writting. If your brakes fail in the near future you can point to that written statement. If the repairer refuses to put anything in writing, I'd assume your being lied to.

If you check, the replacement the dealer installed in your car was likely a "certa" unit which is another word for a factory rebuild. Therefore a rebuilt transmission will not be anything "new"
If you press the issue, you will likely get Jag to replace yours with another certa unit. You may need to make a bit more "noise" though.
In choosing a private shop to do this work, ask around and see who has a really good reputation."Branded" shops are franchises and as different as dogs and cats when it comes to quality. If you have friends with a similar car, see who they have used. If you use a private repair shop ask who they "job" their trans work out to.
It may take a bit of shopping but you likely will find someone who can do the right job for you!

well you have a misfire on #2 cylinder (po302). possible bad coil or wire. hard to estimate cost without diagnosing first.po 705 is transmission range circuit. possible bad prndl switch or out of adjustment. Again would need further diagnosis to estimate.
