Well i ust picked up a clean 06 ser with 92k miles and of course as soon as I get half way home trans starts acting up. Hard shifts etc so I took it into out local trans shop(he does good work). He is telling me to go with a oem nissan updated valve body of a rebuilt one like level 10 . Has anyone installed the new updated valve body from nissan over a rebuilt . I read mixed results on these rebuilt ones and my trans guy is telling me I'll be back if I go cheaper route . Thoughts ?
