jmoss5723 Posted October 20, 2016 Share Posted October 20, 2016 (edited) I have a good automatic transmission from a 2003 Forester X. There is a really clean 2000 Forester for sale nearby that needs a tranny. Could I buy the car and drop my trans in and go? If it is not plug and play, does anyone know what I would need to modify? New idea. Swap my reliable, lowish mileage engine and 5 speed tranny from 2004 SG into the 2000 SF. Junk the non-functional SF automatic transmission. Install the auto from the 2003 SG and the motor from the 2000 SF into the 2004 SG. Obviously I would need to swap pedal boxes, clutch cylinders, etc.,too. Then I would sell the 2004 SG and keep the really clean 2000 SF which now has a reliable motor and 5 speed trans. Am I insane?

86BRATMAN Posted October 20, 2016 Share Posted October 20, 2016 I've done several difficult and different swaps in my days. But I think I'd rather throw myself in front of a moving car that attempt what you're thinking of doing. The complete wiring harness from the 00 will have to go into the 04. Every. Last. Bit. And that's just the beginning. Many of the body side connections are different; lights, door harnesses, dash harness, the 04 has dbw where the 00 is cable. I could continue but I'll stop there.

jmoss5723 Posted October 20, 2016 Author Share Posted October 20, 2016 This is the kind of info that I came for. Thanks. I've decided that I'd like to try something simpler anyway. This just solidifies that idea. The new plan is to buy the 2000 and just replace it's bad auto trans with the auto trans from the 2003 then sell it for profit. I believe that it should work mechanically, but will the wiring be plug-n-play or close to it? Will the shift linkages hook up properly? The trans codes and gear ratios are below. Year: 2000 TY755VC1BA 1st: 3.545 2nd: 2.111 3rd: 1.448 4th: 1.088 5th: 0.780 Rev: 3.333 Final: 4.111 Year: 2003 TY755VC3AA 1st: 3.454 2nd: 2.062 3rd: 1.448 4th: 1.088 5th: 0.780 Rev: 3.333 Final: 4.111 Link to comment Share on other sites More sharing options...
86BRATMAN Posted October 20, 2016 Share Posted October 20, 2016 The code may be different, but they are electronically compatible. And it looks like the final drive ratio is the same. There should be no problems swapping these. 1 Link to comment Share on other sites More sharing options...

86BRATMAN Posted October 21, 2016 Share Posted October 21, 2016 If it helps, my old 99 legacy gt has been running an 02 impreza RS 4eat for 2 years. Link to comment Share on other sites More sharing options...
