P0731, P1732, P0733

Those are the codes I am getting right now on my truck. I just replaced the transmission solenoid pack and refilled with fluid because I was getting slipping and clunking into 2nd and 3rd gear. It was sporadic. I was getting a solenoid code before plus those other codes. The fluid looked and smelled great when I was changing it. No burnt smell or chunks of metal in the pan. I was hoping I was not having to replace my transmission because of that. Just in case anyone asks yes I did use ATF+4.

Thanks!
