I have a 1986 Pontiac Trans Am it looses power when warmed

Customer Question

I have a 1986 Pontiac Trans Am it looses power when warmed up. Was told there is a sensor that is probably bad in the 700R4 Trans, also my car runs at a temperature of 230* is that normal?

Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
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. JA is a great Q/A site, but it does NOT replace a
repair shop.
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.

The KNOCK sensor can be retarding the timing making it sluggish, but it's not in the trans. Nothing in the trans to cause this with any sensors.

Thanks, Ron
