Hi, I’m Ron and I’ll be helping you today.

Before we get started though, please understand that I don't know your skill level or tools you have to assist us. Also understand that I can't see,smell, hear, or touch the vehicle either, so patience is appreciated.

My goal is to make you happy and get a great rating in return for my time.Sometimes I have to give you bad news that I know you didn’t want to hear, so please don’t shoot the messenger.

We need to identify the problem starting with fluid level and color. Then we need to operate the shift solenoids with a scan tool in bidirectional mode. After that, we need to drop the pan and do an inspection looking for metal shavings, checking the valve body and clutches.

Thanks, Ron

Not happy with response didn't answer my question at all

Yes I did, the preliminaries need to be done first, then once you have a scan tool attached is when the other questions will be answered. We need DATA first, no guesswork will work with this issue.

Thanks again, and please remember to rate me and keep this link in case you still need me later on, which you probably will.

Ron
