jelly man Posted December 13, 2005 Share Posted December 13, 2005 I'm swapping the awd auto drivetrain from a 91 legacy wagon into a 92 fwd auto sedan. The mechanical parts are going fine except the torque converter. Is the converter from a fwd tranny the same as one from an awd? I need to know what electrical parts (TCU, relays, wiring, etc.) that I NEED to swap also. I'd like to swap as little as need be. Quote Link to comment Share on other sites More sharing options...
gen1lover Posted December 13, 2005 Share Posted December 13, 2005 I know in 93 the torque converters are the same Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted December 14, 2005 Share Posted December 14, 2005 Yeah I would think the torque converters are the same. As for electrical, I believe the only thing different on the AWD's is the duty c solenoid. So you should just verify that the pins for that sensor is there. I'd have to look at things more closely, to be absolutely sure, but you should be able to d/l the tcu i/o from my server. Quote Link to comment Share on other sites More sharing options...
jelly man Posted December 24, 2005 Author Share Posted December 24, 2005 A very important note. The TCU's are not the same. My tranny was howling very loudly. I pulled the new TCU and it is stamped 2wd. I pulled the old TCU and it was stamped 4wd. I checked the number of pins on each box and they still are the same. I swapped them and the problem is now fixed. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted December 25, 2005 Share Posted December 25, 2005 That's good to know they aren't the same. The FWD TCU probably doesn't have the programming to control the AWD. Quote Link to comment Share on other sites More sharing options...
