You can update this message at anytime. - I'm sorry to hear about any troubles with the vehicle, but would be glad to try and help! - Usually internal transmission issue is the cause of these codes, but have seen some wiring/loose connections at times. Attaching the test procedures for both codes to the message to help with the diagnosis, may need to be on pc/email platform to view. - Lemme know what youre seeing, or if any questions come up while checking things out!

you're saying these all internal problems? My warranty company is denying the claim
Automotive Expert
Im just providing the diagnostic information. Please lemme know if any questions come up while checking things out!

I'm sorry I'm just a bit confused I was at yourmechanic.com and thought I was scheduling a diagnostic for $90 or so but got forwarded to JustAnswers. But I'll give it a shot to see if anything I can use to find proper diagnostic
Automotive Expert
No problem at all, sorry for any confusion with the site, but would be glad to try and help figure out what's going on with the transmission, if having any issues with the diagnosis. Not sure about the warranty company coverages, but I'm sure we can at least figure out if transmission needs to be replaced, or if there's an issue with the wiring or transmission computer. Lemme know if there's anything I can do to help, or if any questions come up while checking things out!

Sorry for the delay, just getting back from supper. Unfortunately I don't think repairs will be covered by the warranty. I'm seeing under "What is not covered, line 2" issues with transmission sensors and valve body will not allow coverage for transmission replacement. - Are there any dedicated transmission rebuild shops in town? Would have one take a 2nd look and see if just the valve body/tcm can be replaced at this time, instead of complete transmission, but I'm not seeing the valve body listed as one of the covered items of the plan. - Please lemme know if there's anything I can do to help, or if any questions come up while checking things out!

Thank you for the info. How much do you think a repair like that will cost ?
Automotive Expert
Good morning, sorry for any delay, just seeing your message Expecting replacement costs for valve body would less than $1K, while transmission replacement costs should be in the $2K-$5K range. Please lemme know what ya find out, or if there's anything I can do to help/any other questions come up! Thanks again for using JustAnswer.com!

replacing the valve body first might fix the issue.?
Automotive Expert
Hello! Yes, the valve body may have failed. Recommend having reputable transmission shop run the tests for the codes that are setting to see what's going on. Lemme know if any questions come up while getting it checked out! Thanks again for using JustAnswer.com!
