I just changed the trans. In my 1994 cadillac eldorado. I put in a trans. From a 1994 deville now is when iam getting the code p029. I checked the solinoids and they checked ok. I didn't clear the codes from the old trans, will that give me a problem? Both transmissions are 4t80e but the deville has 19 pins and the eldorado has 14 pins, are they wired different? Both cars where with a y. The trans doesn't shift to 3rd gear and let off throttle and goes freewheel.
have the same problem?
