Are you getting shift solenoids codes? Is the tranny fluid low or burnt?

William Holder

I'm not getting codes and the fluid is new I got the transmission out of a older car and the numbers on the new transmission does not match the computer on the firewall


The tranny must be an OBD 2 transmission for it to work, OBD 1's will not work even if they bolt up.

What is OBD


Onboard Computer Diagnostic System. There is OBD 1 and 2 depending on the year your rig was manufactured. As your is a 2004 that makes it an OBD 2 vehicle.

William Holder

The car has a 4 plug computer and the car the transmission came out ofhad a 2 plug ccomputer on the firewall


That won't work, sounds like a wrong tranny.

William Holder

Yeah but is the solenoid block the only computer in the transmission


Inside yes, check the ident plate on the both trannys, the numbers should match if they don't then it is doubtful that it will work. Sometimes a manufacture will make another tranny that will work a year or two later and change the number, you can check the dealer or even a wrecking yard for a compatibility from year to year. You will need both numbers to do this.

Could u not change solenoid block to the one that matches the firewall and they would both match and work then wouldn't it


They are not too hard to take off and check the valve ports to see if they match, my book says no it won't but it also said that an intake manifold I had wouldn't on an engine I was building but it did, so nothing is etched in stone.
