Don't ask me why....but even though the coolant temp sensors don't throw a CEL or test ok....they can still be the culprit.

They are sometimes taped up on the wiring loom. You may need to remove the TCU to see them. That's what I had to do. This thread has pictures http://www.ultimatesubaru.org/forum/showthread.php?t=33488

I wouldn't run straight syncromesh because I don't believe it's GL 5 rated.

It's not quite a direct swap. Is her car and the donor automatic or manual? There were some sensor differences between the 90-91 MY's and the 92-94 MY's. The engine electrical connector plug changed I think mid year....so that may be something you'll have to look into. It's not a big deal...you just have to swap the electrical harness.

I have a picture....that's it http://www.main.experiencetherave.com:8080/subaru/images/transfilter.jpg Are you wanting to know how to install it?

Refresh my mind on what setup you're doing. Basically you want to keep the sensors associated with the ECU. The sensors in question are: MAF Sensor IAC Valve Injectors The wiring harness of the car that's going to receive everything will also play a role in which ECU, Hitachi or JECS you use.

There's no way to adjust it. Only thing you can do is manually move the gear selector to the 1 or 2 position.

coolant temp sensor. They can cause issues, but not give a CEL. You can get one for like 20 bucks at www.subarugenuineparts.com

You can do what you want....it really doesn't make much difference to me. My recommendation to leave them on is due to the fact that any dirt and other junk that gets in contact with the belt, pullies, etc will shorten the life of the belt, and the idler pullies. If you don't care about that.....then leave them off.

The 3rd gear grind is probably the synchro. Replace the fluid, see if that helps. You can add a little bit of penzoil synchromesh to help. If none of that helps, you or the next owner will just have to live with it. The first gen legacies are OBD1. Instructions to pull the codes & code info is on my site www.surrealmirage.com/subaru/engine.html Yes there are two cats. One in the header pipe, and one in the mid pipe.

The car's computer controls the idle via the idle air control valve. The valves can sometimes get sticky with carbon and not respond as smoothly as they should. You can squirt brake cleaner down in there. I would check for vacuum leaks and the normal stuff as well.

Glad to hear it worked.

Anything's possible??

goo gone won't harm the paint, however it will strip the wax, so you'll need to re wax that section.

You should keep the covers on to help keep debris and junk out of there. Especially since you're going to be offroading. Go to a junkyard and find a used set.

Yeah a solenoid controls lockup. I think it's the duty b solenoid

The 90-91 Legacies & 92-94 legacies do have some differences. The electrical harness between the two are different. As you noticed, the 92 engine harness won't plug into the 90-91. There are a few other things here and there, but for the most part things are pretty similar. Do check out the legacycentral bbs. A lot of good info on there.

Read the instructions on my site. http://www.surrealmirage.com/subaru/engine.html Here is a pic of the connectors http://www.main.experiencetherave.com:8080/subaru/images/ecuhide.jpg

Does sound like an issue with the torque converter locking up/not locking up. Not sure what the fix would be though.

You need to find out the specific code that is being stored. That will make troubleshooting the problem easier.

The 90-91 AT & MT legacies had different sensors. The ignitor, coil pack, injectors, IAC valve, MAF sensor, and ECU are different. The ignitor & coil pack won't really matter. The injectors are timed slightly different, so your mixture will not be right on. I'd suggest swapping the AT injectors in. Also, the IAC valve on the AT's is a rotary type valve, compared to the MT's recipricating valve. The MAF sensor is also different. Swap the IAC valve & injectors from the AT car. Also, sounds like your coolant temp sensor is bad. Did you check the codes? Do that before you do anything else. The computer is telling you what it doesn't like....

When the shutter happens, what happens if you move the gear selector from Drive to Neutral? Does the shutter go away, or continue?

Nice tip! Welcome to the forum.

Sounds like the shift lock system is messing up. It could be the controller, it might be one of the sensors too.
