my transmission is slipping or sputtering when going in and out of overdrive. its only when the car is at operating temperature and is only for about a second or two. there was no check engine light but i went ahead and did the download and got a code 23 (Intake air temp sensor out of range). Im pretty sure these two problems are not related, does anyone know what can be causing the tranny slip? Also where is the air temp sensor located? thanks!
