Why does my tranny hate me?

Before I begin, let me just say that I am going to keep driving on this tranny until it explodes, or I have the time, money, and alternate transportation necessary to do things right.

Now...

Quick recap:
First tranny - asplode
Second - broken forks
Third - apparent bearing problem; massive "gear whine"
Fourth - was working just great, until today...

The "gear whine" is back. It's LOUD in first. You can clearly hear it from the street. Second is quiet, third is inaudible. It only makes the noise under acceleration. It goes up in volume and pitch with engine RPM.

Dunno if it's bearings, gear teeth, or what. This has happened before, and I put more than 400 miles on it before I bothered to take it in for an almost-free rebuild. I'm not terribly worried. I'm just pissed that it decided to come back.

When I can afford to buy the oil, and can get some garage time, I'll go ahead and drain the tranny fluid to see what it looks like. But it *is* the holidays, so I'm both broke and out of spare time. If this thing ends up needing another rebuild, I'm going to spend the money on a plane ticket to Germany so I can burn down the Getrag HQ.

Also, if it needs another rebuild, I will *NOT* be taking it to any local tranny shop. Either I rebuild it myself, in my living room, or I have somebody I KNOW is qualified and experienced with these 5spd AWD trannies do the job.

I'm getting sick of this crap.

On the bright side, I was pissed enough to accept a quick highway race against a local ricer. Guy had a DSM that obviously had more money in exhaust and body than in engine. I was just cruising up "the hill" on the way home at around 60, and he's trying to goad me into a race. "Fine" I say, and wait for him to open up. He punches it (haw), so I downshift to 3rd and do the same. About 3 seconds later I'm past him with enough space to move into his lane.

Amazingly enough the tranny didn't make a peep during the sprint, and I felt much better about myself after picking on a slow-ass car. I'm such a big man. Tomorrow I plan on kicking a few defenseless chihuahuas and making a cripple slap themself while saying "stop hitting yourself. stop hitting yourself."

My tranny makes the sound that makes me punch infants! (apologies to Dane Cook)

Err, no offense, but if you are going through trannies like that I'm going to suggest you learn how to drive before you put another one in there, or you need to tripple check all your fluids before you drive anywhere, everyday.
I put a bunch of drag passes as well as daily driving before I wore out a single synchro to the point that it needed a rebuild (3rd by the way). So to recap, make sure you have a suitable oil in the tranny, make sure it's filled to where it's supposed to be, and go easy on it.

1) Take a video or something of this gear whine--- i used to be scared shitless of my gear whine, after my new tranny it did the same thing and i heard other 3/s's doing it so I figure its normal for our trannies? i get some alternator whine too, which i used to think was gear whine

2) dane cook rules

Been driving manuals for over 10 years now. Never had any problems with any of them until I got into this one.

There's a trick you're missing here, and one that I didn't feel like re-posting: Three of those four were sourced through AAMCO.

Dun dun dunnnnnn!

It's called "piece of shit parts = piece of shit tranny."

The one and only reason I went back to them several times, is that all of those were covered under warranty, so the repairs were free.

Like I implied in my first post - it's the builder's fault. From now on, either a trusted builder does the job, or I do it myself.

So, no offense, but I'm going to suggest you stuff your shit back in your hole where it belongs. :)

Learn how to drive, my ass... Until you've seen how I drive, you don't have any ground to stand on, and are just being a jerk for the sake of being a jerk.

EDIT: BTW Slage, like the new sig pic. Great shot.

Just callin 'em like I see 'em. Someone comes up and says "Hey I broke 4 trannies over the past year and I'm not even drag racing it!" I will point out that they must obviously suck at driving. Had you mentioned that you were using gears made out of paper-mache and dreams then I would have reevaluated my initial comment.

So, next time you decide to make a post about how you brake parts left and right you may want to include pertinent details if you don't want to be called a retard.

woah woah calm down there ducky.

These cars like to break parts all the time. A bad install or re-build of a tranny can tear it into pieces in no time at all. Ive seen him drive, been on a couple cruises with him, he doesnt drive hard at all.

LOL! You wouldn't drive hard either, if the first tranny (the one that came with the car stock) blew up at 70mph! Methinks the previous owner never swapped gear oil, so the thing grenaded on me on I-5 (right after *I* replaced the oil - the old oil was SLUDGE).

I'll put the screws to it when I'm already *in* gear, but I'd never powershift or drop the hammer on this sucker. At least I was able to keep up with Erik and Rusty. :D

And the reason I didn't post up the "it came from AAMCO" statement in the first place is that most people who've seen me post in the past have read of my "issues" with that damn shop. I didn't feel like re-hashing the past, so much as getting out my frustrations at having such chronic problems. I'm beginning to think that they sourced their bearings from junkyards instead of buying new parts.

Since they've already spent more on labor alone than what I paid them for the first swap, I came out "ahead" in the AAMCO deal, but that still leaves me with a time-bomb tranny and an empty wallet.

From the sounds though, I can't decide if it's a bearing, or if one of the gears has chipped. Inputs are moving way faster than outputs when in 1st and 2nd, and that's where it's loudest (can't hear it in 3rd or higher). Only makes the noise when torque is applied to the tranny, so it really makes me think "bearing." Once I'm in 3rd and things even out, I can't hear the sound at all.

I'm also re-thinking my use of Redline for the tranny. I'm going to be swapping the oil again soon, and try some Royal Purple to see if the sound clears up. The two times this has happened to me, I was using a 60/40 mix of MT-90/MTL, and both times happened soon after I did a WOT pull in 2nd gear (on-ramp) after a granny-shift. I don't expect it'll get any better though, since I'm paranoid enough to think that the bearing retainer has broken, so they are rolling mostly-loose in their race (would explain the symptoms).

Whoa, I should probably get to work. I've been at the office for over an hour, and only addressed one client file! Oh well, they don't pay me enough to be quick about things...
