kevsev7k Posted September 24, 2021 Share Posted September 24, 2021 93 Impreza L wagon: I drove to Chicago a couple months ago and had no trouble. Came back and the next day, driving 50 mph the stick popped out of gear and would not get back into gear. When my timing belt broke a few years ago, the same thing happened. Ordered the water pump kit through rockauto and have had it for a while. Haven't fixed my car because I also have a truck. Truck is broke down so I decided to change the belt. After taking everything apart, the belt was still in tact so I changed it anyway. Put everything back together, started it and tried to drive. Light smoke and burning smell came from above the transmission area. I checked the trans fluid and was dry. About 6 years ago, my trans had a fluid leak so my buddy and I opened up the transmission and replaced the seal along with something else (I can't remember). I filled the transmission fluid, using 90w gear oil. Gears still won't engage, more light smoke and burning smell. Please tell me I didn't "F" my transmission, any help is appreciated.

heartless Posted September 24, 2021 Share Posted September 24, 2021 first off - manual or auto? and where did you fill with gear oil? there are 2 different systems on an auto - passenger side gets gear oil (front diff), drivers side gets ATF Link to comment Share on other sites More sharing options...
kevsev7k Posted September 24, 2021 Author Share Posted September 24, 2021 Sorry, 5 speed manual. I filled on passenger side. Link to comment Share on other sites More sharing options...
idosubaru Posted September 24, 2021 Share Posted September 24, 2021 (edited) How do you know it's not the clutch? If clutch is fried it won't go into gear either. How "dry" was it - completely empty? It doesn't go into any gear? The cable and fork are moving in and out properly with the clutch pedal? Have you tried putting it in every gear and jamming the stick in hard? What happens if you try to turn the wheels/axle by hand (or with tools) - will they turn (ebrake off)? if both front axles turn with no play/noise, then the front diff should be fine. But there's still the gears and synchros. I'd guess maybe the synchro's are smoked due to lack of fluid. You could drain the fluid and see if you get chunks, sparklies, how much, or nothing in the fluid. Check fluid carefully in a pan/with some white cloth.

1 Lucky Texan Posted September 24, 2021 Share Posted September 24, 2021 cracked/broken fork could be in the mix here..... 1 Link to comment Share on other sites More sharing options...
kevsev7k Posted September 24, 2021 Author Share Posted September 24, 2021 Since I parked it, I've left the e-brake off and in 1st gear. I'm able to move it by pushing back and forth. Just started it and had it in 1st gear, let off the clutch and nothing happened. I thought maybe it would stall but it acted as tho I had my foot on the accelerator. When I gave it gas, that's when a slight grinding noise started (was very slight) and the white smoke appeared where the trans meets the engine. It will go into gear and the clutch works fine. Yes, when I put fluid in the trans yesterday it seemed to be completely dry. I added about 2 qts before the level on the dip stick came up. Today I don't have time to drain the fluid as I'm trying to get my truck going. I'll have more time tomorrow. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 24, 2021 Share Posted September 24, 2021 does the smoke smell really bad? if so, gear oil or possibly cv joint grease. if not, coolant is sweet-ish smelling, the smoke really doesn't make sense but, symptoms somewhat line-up with a broken axle so, I'm going with 'you need a transmission - time to call car-part.com' Link to comment Share on other sites More sharing options...
kevsev7k Posted September 24, 2021 Author Share Posted September 24, 2021 Tried this again, car is started. Push clutch in and put in 1st gear. Let off clutch and car acted like it wants to move forward but doesn't. Also Tried reverse, let out on clutch and acted like it wants to move but doesn't. Back when I had a bad seal I had to add gear fluid to drive, they smoke smell doesn't smell like that. And the smoke doesn't appear until I give it gas. The smell isn't as filthy smelling as oil, it's more of a light bitter smell. I don't know how else to describe it. Side note, 2nd 3rd and 4th gears don't give me the impression the car wants to move like 1st and reverse. When I put it in 5th, the engine shakes.

idosubaru Posted September 24, 2021 Share Posted September 24, 2021 I have no idea. Sounds like clutch/cable/fork related to me, but this kind of stuff doesn't happen enough for me to have any statistically meaningful feedback. If it was a transmission issue I'd think you'd feel or hear noises like synchros crunching/grinding or bearings/diff whine/clunk/etc. But I've never seen what a MT Subaru trans does when it's run out of gear oil so I don't have any reference for that. I'd wonder if you can find someone who's destoryed a trans due to oil starvation and see what the symptoms were? 1 Link to comment Share on other sites More sharing options...
heartless Posted September 24, 2021 Share Posted September 24, 2021 definitely sounds clutch related to me.. but then.. has been a while since i have had one,... 1 Link to comment Share on other sites More sharing options...
forester2002s Posted September 25, 2021 Share Posted September 25, 2021 Sounds like the clutch is slipping. Could be worn clutch-plate, or throw-out bearing, or clutch-fork. The lack of oil in the MT is puzzling. Involute gears can't run for long without oil, and will self-destruct pretty quickly. Link to comment Share on other sites More sharing options...
forester2002s Posted September 25, 2021 Share Posted September 25, 2021 MT could have seized from lack of lubrication. Then clutch slips and smokes each time you try to move the car, and the clutch-plate may now be worn down so it slips continually. Link to comment Share on other sites More sharing options...
lmdew Posted September 26, 2021 Share Posted September 26, 2021 Drop the trans. Inspect the Clutch side. Test the trans. Replace as needed. As someone said earlier, check the trans gear fluid when you drain it. Link to comment Share on other sites More sharing options...
