Hey guys a few weeks ago I was asking about the auto to manual swap. I completed it in a weekend in a dirt driveway, on jack stands. Was very easy, I will say tho all the write ups were too full of little details and not full of the important details that you really need. Example: all the write ups I went to were very vague on how to correct the ECU from auto to manual, after getting schematics of the ecu it was really easy, consisted of sniping a wire. My swap was much easier then the write ups were. So, I am on here to see if anyone would like a write up on this. It would take quite a bit of time; but I'm willing to write it up in a simpler format, with the basics that you will need to do this swap if anyone is interested. I did my swap on a 93 legacy sport. Let me tell you, if you have an auto; SWAP IT. made the hugest difference in power, fun and drive-ability. I originally bought the car with a auto tranny that was shitting out and got lucky enough to find a transmission that match my rear diff. I run a 5 speed 3.90 rear and trans now and let me tell you I only use 5th on the highway cause it's geared so long. I will say one thing tho, I put a stage 3, 6 puck clutch in mine. Yes good for track and strip but next clutch is going to be a stage 2, cause the 6 puck grabs way to hard on the street. So if anyone wants to see a write up let me know, or if you have any questions about the swap feel free to ask away.

Did you use a cable clutch tranny or hydraulic? From what car?

I used a cable clutch trans out of a 97 legacy wagon. It's way easier to install, and I think you get a better feeling with the cable. I took the axles, shifter linkage, trans subframe, and flywheel all from the same car. after I took the driveshaft from trans to rear driveshaft from earlier model legacy wagon (auto trans) based on the size I needed (Pre-measured). Before the trip to the junk yard I cross referenced the trans so I wouldn't have to get a different diff.

-I'd like to see a write up on this. I have a swap with the 4.11 diff. and I completely hate the gearing. Plus tranny syncros are getting a little weak so another swap will be coming in the future, but in my case I'll need a tranny and a 3.90 diff.

Do the write-up. I think this will become more common as the SS/TW's 4EAT fail and more people want to do this swap which is much cheaper than a rebuild.

I used the 'Streetlite' clutch on my swap and it worked well. I also thought the cable clutch gave better feel.

I didn't think Legacy777's write-up was vague and I find wiring issues challenging.


Thanks,

MeinKruz, is it a sprung- or solid hub clutch disc?

Caveman, Whats not to like about shorter gearing? Shorter gears = faster acceleration.

Shorter gears = higher revs on the freeway and lower fuel economy, which to many people is more important than closer 1-4 in a car that's already got abundant torque. Particularly if it's a daily driver. If it's a weekend car, then I'd have to concur with you though.

-Well being it is a daily driver, 1st gear is pointless and 4000 rpms in 5th @ 82 mph, give or take, is just ridiculous. My top end sux. I can get to bout 126-130 mph and that's it, just dies from there, but I do like how quick it gets there. I think the 3.90 is a good match. I will agree though, if it was a weekend or rally car, the 4.11 would prob. be ideal.
-The only thing I do like about the 4.11 is, punching it in 5th at 75 mph is nice, cause your in your powerband... you don't have to downshift. But you quickly run out of rpms.

-Joe

Even with a stock 3.90 turbo trans 1st is pretty useless. Maybe on stock boost it would be nice but all 1st does for me is spin a tire or two, feel like something is gonna break then it's over about .9 seconds later. I wish first was a little taller so there was a little less gap between first and second.

And I can build 18psi at 2500RPM so 65+ in 5th gets me crazy torque too. It still accelerates faster if I downshift though.

I do mention the ECU AT/MT pin in my write-up
