Tranny or Clutch

Well I've blown up one or the other or hell both, I dunno. But I am wondering the best symptoms to look for to determine which has gone bad.

With the car on I can not put the car into gear, which would make me think that I am having a clutch or pressure plate issue. But with the car off, I am not getting perfect or smooth shifts into gear, which makes me think that I may have blown up the gear box. I am not exactly a saint when driving my girl and this isn't the first tranny I may have killed.

Ideas or a link I can check out?

I guess you could try opening the window with the engine running then depress the clutch in and out and listen if you have damaged the clutch plate I expect it will make a lot of noise. My clutch has worn out and I can tell because it slips especially in the higher gears. I will be changing my clutch this weekend if you want me to take any pictures of it apart let me know (not that I will be opening up the transmission).

Not recommended, but you put the car in 1st gear then turn on the engine the starter motor will move the car forward if the transmission is working. I would only try this as a last resort, Hopefully someone else will have a better idea for you

Nope no noise. She sounds perfectly normal. Hydraulics are fine as far as I can tell, plenty of fluid and such. Clutch pedal feels normal and I have the pedal reinforced not too long ago, the bracket is still in tact. She never slipped in any gear, in fact... I have zero warning of this happening at all. None of the gears grinded and the clutch never slipped. Which is why I am confused. Could be something as stupid as a throw out bearing.

I've installed a two trannies on my girl before. Like I said I am no saint when driving her. But I want to buy the appropriate part to put in if I drop the tranny. I don't really want to drop it just to figure it out but I think I just might have to go that route.

Unless anyone else has some other ideas to help diagnose without dropping the transmission.

Not sure I can help you really....
When you try to put it in gear with the engine running does the gear lever move into place and no gear is selected or will it not slide into the gear

Well I would put my money on it being the transmission. It sound like the gears are not lining up correctly. I think if you had a clutch issue it would grind as you pushed it into gear.
When the car is off try putting it into gear and listening for strange noises it might be worth getting someone else to run through the gear box and get you head under the car.
When did it start happening? Driving hard, when you tried to start it, if it happened when you were driving did it make any noises

Happened when I was driving, I was going about 25 off and off ramp and engine broke to second. I heard a little "thunk" when I got the car into gear. I came to a calm stop because of traffic and then had a problem getting the car out of gear. Once I did, I couldn't get her back into any gear.

It sounds like something got misaligned in the transmission somewhere. If you are confident about taking the transmission off I would take it apart and have a look inside you will probably be able to replace a part within the transmission if you can get somewhere that can give you the correct part. I used for fix communications equipment and things like that become obvious what is wrong when you can look at the actual parts.
If you cannot repair it or mess it up you need to replace the transmission anyway so you lose a bit of time and gain some experience

Fixing the transmission yourself is not really an option Chunn. Most local transmission shops will not even touch this Aisen transmission. It's hard to say what is wrong but if you are going to pull it you might as well replace the clutch anyway.

Taking the transmission down is not a big deal... Done it twice on my car and once on another member's 8. If I don't see anything at the clutch or throw out bearing, I'll debate opening the transmission. Not super confident with that idea but I see your point.

Might also be worth bringing it somewhere to be checked out.

ACK! I really don't want to do both dude. Clutch and transmission is more bank that I am willing to spend.

You can call around and see, there may be some shops with experience tearing newer type Aisens apart but the few shop I contacted here wanted no part of it and the shop I did find in Dallas quoted me more than what I could get a used 2009 tranny.

I think you should just take it apart inspect clutch then change the transmission, eee if you can find a used transmission and swap it out.
If you were in Sarasota this weekend I would let you borrow my transmission to test it if you helped me change my clutch.

Wright, I did try starting the car with it in gear, she tried to move in both first and second. I didn't try third because the process was freaking me out a little.

9K, if the tranny is bad, I am going to replace it. If I take it out to have someone look at it, it is make sure that it has died. I won't try to fix it as I wouldn't feel confident in attempting that one. If we can absolutely say that I have busted another transmission, I'll just replace it. Really really REALLY hoping that the clutch does not need to go as well!

If the car is moving in gear then it sounds like the gears are in the right place. I think you may have a problem with the selector. To be honest I really don't know enough about the whole process to advise you properly. I would see if you can find a mechanic and talk about the issue. I don't think it would have to be a Mazda mechanic either. Maybe call a transmission specialist who is local to your area.

Thanks for the input Wright and 9K! Hey if you guys come across a transmission, either series, let me know. I think I might be in the market for one.

Power plant bar? Yup I am sure, I was super careful about that thing. Even went back underneath after driving her for a bit to make sure. I've made that mistake in the past.

EDIT: Oh wait a minute!!!! I didn't check it since the tranny went. Holy ****! Imagine it was that SIMPLE?!?

I had that issue when installing the beat Rush brace on Hoss-05's car. I let the tranny drop when installing it and afterwards there was a ton of noise and it would pop out of gear. I realigned it and everything was back to normal. It could be something that simple

Knowing my luck it won't be that simple but I will certainly check it when I get home. The engine was recently replaced but you never know, maybe those bolts weren't tightened enough and the damn thing moved just enough.

Good luck man hopefully something has just moved out of place enough to stop it working correctly. I bet that will make your day if a few turns on the old torque wrench will sort it out for you.

No luck on the Power Plant Bar... dropping the tranny this weekend and we'll see what's up.
