If the metal exposed by the missing chunk is nice and shiney, then he probably need break it off. Otherhand, dull and tarnished-looking then most likely an old crack.

Broken timing belt?

This transmission has an ATF temperature sensor. When it fails you get the symptoms you described. Easy repair and not expensive.

Ignore single digit codes. They indicate things like automatic/manual/California equipped.

Replace the AFM.

I've towed 2 AWD XT6s with a dolley and with just the driveshafts removed probably a total of 500 miles. Had no problems whatsoever and still drive both cars. Won't hesitate to tow another cross country if needed.

Some radios have a fuse located on the backside. Others have an inline fuse in the harness.

First, this was a fairly rare option if I recall correctly. Offered only in 88, 89, and 90. The same transmission used in the first generation Legacy has a different bellhousing which means you would have to use your differential. Don't think there are any major differences between the turbo and nonturbo models. Maybe a different valve body but I suspect both are identical. Only thing not sure about is the spline count on the differential stubby shafts. Easy enough to find out if the turbo and nonturbo models used different CV axles.

You have the 4EAT. Essentially the same transmission Subaru used in the LEGACY/IMPREZA models until around 1996. Bellhousing bolt pattern different but that's about it.

A hydralic press will remove that broken bolt, but is it even worth it? NA Subaru heads are a dime a dozen.

Just pull the splined stubs from the old differential. They will pull free. Only held in place by a weak snap ring. DON"T remove any of the bolts around the differential where the stubs insert. To reinstall in the "new" differential, just push them in until that snap ring clicks into place.

Did you remove that tapered washer located behind the nut?

I used Maaco a few years ago. Paid for the "premium" service. $900 wasted. Just terrible. I have no idea how Maaco remains in business. Under the topcoat is suppose to be a coat of primer-sealer. At least I paid for it. But where the topcoat has flaked off I can see Maaco didn't even bother the primer the car. I won't let Maaco repaint any vehicle of mine. Forgot to mention the shifter. I was told if I brought the car in on Sat. it would be ready Mon. Monday turned into Sat. I thought it was nice that the car was placed in front of the shop when I went to get it. Learned why after I got home and went to back out the driveway. The shifter fell apart went I went to place it into reverse. Just one of those things? I don't think so.

The FWD and AWD transaxle, at least on the XT6, have different harnesses. EG, the VSS is internal on one type and external on the other type. If you used the stock harness unmodified than this at least is wrong. May want to compare the pinouts at the transmission connection. More than likely all those gears not working is because current is not reaching the appropriate solenoids.

Your probably right. I never crosschecked the manual version. I should know better than to use words like "all' and "always". Always seem to be exceptions to everything.

Had the exact same problem in my 95 wagon. Problem was solved by replacing the air flow meter. Any Legacy AFM from 90 to 99, except the turbo model, will interchange. I got lucky and found a used one for $10.
