Question about 1998 Cadillac Catera
THE tcm is not by the battery that is the ecm . which is by battery under the cover
Posted on Jan 02, 2013
Tcm is located beside the battery under a triangle shaped cover it's about 6"x8", silver colored. slides up and out. I had to buy a used one off ebay and had a GM dealer reprogram it. Bad thing is there hard to come by used. They have to have the exact same manufacture number. $100.00 to reprogram it. I shorted my tcm out trying to give some body a jump start, Jumper cable popped off and shorted across metal on the tcm and positive on the battery.
