I replaced the air conditioning converter and some other stuff related the air conditioning becausr I haf an annoying noise. I picked up my car and a day later my suv is having problems shifting and yhe o/d light is coming on. I dropped my suv back off at the shop and they're suppose to check the codes today. Any suggestions?
