Transmission had a bad torque converter and i rebuilt it myself and that gave me 60 K more miles so im happy about that. But now the transmission light is on about the torque lock up clutch which from research indicates worn out bores either in the transmission or the oil pump area. (will cost close to 600 to sleeve and new solenoids)

So instead of trying to fix the misfire which could be oil rings etc its been getting worse lots of things have been tried. I was looking around car auctions for a wrecked low mileage one and found one well 2 with 76K and 87K. but one is 2003 and the other is 2004. I like the 2004 because i can also use the front end and update my front end too while i am at it.

Question is can i swap over the engine and transmission and use my current set up? I know ill have to bring over the other transmission computer and maybe the ECU too but otherwise it looks to be drop in and done. I dont see any major differences.

Anyone seen or know of someone doing that?
