What is the exact code number?

No need to look it up online. Shoebox has a code list SPECIFIC to the LT1 PCM:

If you want a detailed description of the code, what sets it, and what it takes to fix it, there's a free download of the factory service manual for your car, here, courtesy of GaryDoug:

In the meantime, yes, there is a transmission fluid temp sensor inside the transmission. It is part of the transmission fluid pressure switch assembly. But until you answer Shoebox's question on the exact numerical DTC, it's very difficult to help you.

I will be taking it to my buddys today he has a code scanner. I will post it later. Thank you.

We’re you possibly using an OBD-2 scanner? If so, that’s a common mistake, but your 1995 is OBD-1 with a 16-pin OBD-2 “style” DLC connects. Means you need an OBD-1 scanner with a 12-pin to 16-pin adapter, or a 16-pin cable.

My buddy has a scanner that normally reads it. But this time it wouldnt plus its in limp mode. I already replaced the ecm.
