20% .......... you say 20%?  You make it sound as if even that's
acceptable.   That is not for a car costing what it did and what class
it was in.  Hell, you have Detroit Iron pony cars with as much HP,
costing half as much with trans that last routinely the life of the car.
 Granted, its primarily the synchros and that tends to be the weakest
link in most trans .......... however, the failure rate of ours is way
beyond the norm.

You make it sound as if that is acceptable.  How long has the 5th gear
synchro been out.  If it just happened ........ then maybe its
reasonable.  I know with my 93, I drove it from 65k till 105k before
getting it fixed.

If you are grinding gears, has anyone tried adjusting the shift linkages?  I don't have grinding  on my 5-speed, so never had to look at it, but it has fixed this problem in numerous other cars,  including my DSM that was nearly impossible to get into 2nd without grinding until I spent ten  minutes....

wont happen, its not a safety issue, and its not a currently shipping product, and if it WAS its  not a high enough volume one to care.
 
Look at the 7M (turbo and N/A) Supras..they go thu head gaskets at a much greater rate than  you go thu trannies.

Yeah, but maybe a good bunch of damning statistics might bring enough pressure on them to make a  fix available. Suppose we find that HALF of our cars have problems? Nobody ever asked so big a  sample before. People may not  realize that a grind going into 2nd gear is NOT NORMAL.
 
Maybe this discussion will encourage them to go to
http://www.team3s.com/~dschilberg/Getrag/
and report their problems.
 
I don't think any of us expect Mits to recall our trannies, but it sure would be nice if they  offered us replacement synchros or rebuilt trannies at an affordable price. It'd be nice, for  example, if Mits would fix bad trannies for, say, $1200 exchange, including labor (instead of  the current $3,600). Or extend the factory warranty to, say, 100,000 miles.
 
I have no vested interest in this, by the way. My tranny was replaced under warranty at 65,000  miles. Since I have only 82,000 miles on the car, mine is not due to fail again until 130,000  miles.

What's so damning about it?
 
Nobody's been killed by it, there's enough evidence to support a WISE decision for people thinking  about buying a car with that tranny, and its a car no longer in production.
 
Exactly what is Getrag/Mitsu worried about?
 
Cant blame Getrag, because you have no proof Mitsu didn't say "That's good enough" for the final  design.  The evidence almost validates that as well..as no other Getrag product in any other  manufacturer's vehicle has any such issues.
 
Hell, I've got a Getrag rear-end in my Z.

Parts are available and Mitsubishi no longer has anything to do with our transmissions. They  didn't care when the car was in production and they sure as hell won't care now. As to recall, I  said it before the tranny is not  a safety issue.

92 Stealth TT.  Spline shaft output to xfer case failure @ 18k.  New trans has been trouble free  with 40K on the clock.  For that matter, I'm still on the original clutch.  With the last 10K  being from DE events or driving to DE events, and the last 20K under the stress of 16-18psi  boost, I'm satisfied with the durability so far.  For what it's worth, this drive train has never  seen a hard shift or a drop clutch start.  As long as I'm driving, it never will.

You know this makes me wonder how many folks who have had transmission failures were running Red  Line?
 
I don't think too many were or are running Mobil 1 in the old transmissions (91-93), but the  GL-4 Red Line doesn't have the sheer strength of the GL-5. Sheer strength is the ability of the  lubricant to stay between metal parts under pressure.
 
Maybe this should be an element to be added to the survey, just to see if maybe it could be  associated to the lubrication being used that could have caused the failure.

Subject: RE: Team3S: Adjust Survey?
 
I have the 5spd 93 model and after much research, I finally switched to Redline GL-4 in both  transfer case and transmission. I didn't realize that the GL-5 only eats the newer transmission.  I'm sure that I have 4 bolt main and therefore I believe that I also have the newer spline setup  (24-spline is it?) Now the question is...
 
Should I leave in the MTL (GL-4)?
 
Or:
 
1) Get Redline GL-5 gear oil
2) Get a generic GL-5 gear oil
3) any other ideas??
 
and what about the transfer case? Is it important that the transfer case has the same lube as the  transmission (will the lubes seep in from one to the
other)
 
...and seeing that GL-5 eats trannies and not transfer cases (right?), correct me if I'm  wrong...but it would be advisable to get GL-5 in my transfer case in order to take advantage of  its sheer strength.

Subject: Team3S: reverse grinds under high load
 
s\Sure, I probably shouldn't be reversing that quickly. But twice I did, and I heard a loud  grinding sound. The first time, I had the rpms high and the clutch hadn't fully engaged -- foot  was still on the pedal -- when I heard the grind. The second time, I assume the clutch was fully  engaged (my foot was fully off the pedal).  I gave the car a good amount of gas and I heard the  grind again. My xfer case, tranny, and clutch all have 30k miles on them. They've been driven  gently too. The flywheel has 190k miles though. Apparently the dealer that serviced the car at  160k miles said "that flywheel looks fine" ... unfortunately I didn't own the car then, so I  didn't have the chance to say "replace it anyway!"

Subject: Team3S: front brake pad jobs are easy; wear indicators seem to work
 
I'm not here to ask a question this time...  but here's what happened.
 
I was about to go to Tahoe when I heard a metal *tick-tick-tick* from the front left wheel. I  said uh-oh and dropped $70 on snow chains so that I could take the van. But then later on I  thought to myself... how hard could the brake job be? So I bought some pads for the stealth too.  I ended up replacing all the pads in about an hour, and hence I did finally take the stealth on  the trip.
 
The reason I'm saying this is because I've done brake jobs that aren't always straightforward...  sometimes there's delicate springs or holding mechanisms that can be easily broken (my g.f.'s  Mercedes)... or sometimes it's just SO HARD to get all the stuff to stay together (my old  prelude). Also I've experienced that many pads' wear indicators simply don't work [e.g. my van].  In such situations, the driver has no clue as to what's going on until that ugly GRINDING sound  comes from the brakes... [e.g. my van, again!] and then it's probably too late since you've got  grooves in the rotors  ---> meaning you'll have to pay the extra cost of resurfacing or maybe  even replacing the rotors if you waited too long.
 
So my point is... I must say that the Stealth (at least the front end) has been the easiest  brake job that I've ever done. All that you need is the pads themselves, a lug wrench, and a  C-clamp to compress the 4 pistons on each caliper before installing the new pads. When it's time  for your brake job, keep this in mind.

I've had MT-90 in the trans and ShockProof Heavy in the xfer case and rear diff for 45k miles,  no problems.  As I stated in my reply to the trans survey, the synchros were showing signs of  wear when I bought the car with 34k, and after an additional 56k miles (MT-90 went in after 11k,  90k on the clock now), the synchros are about the same.

All the manual trannies in 3/S cars have copper synchro rings and all are susceptible to copper  erosion by using GL5 fluids containing chlorides.  If your fluid contains chlorides (which  Mobil1 does - at least a few years ago it did) then you should swap it out for a fluid which  doesn't contain chlorides.
 
Just because the fluid says it is GL4 or GL5 doesn't mean it is "safe".  To make it more  confusing, GL5 is not necessarily better than GL4.  For the synchros to work their best, you  need the right formulation fluid and GL4 "seems" to work better than GL5.

      08/12/2002  GL-4 Vs. GL-5 Gear Lubricants
         I have used Mobil 1 75-90 gear oil in the manual transmission, transfer case and front  differential (4-wheel drive). I saw in an "Ask Mobil 1" question that a Triumph manual  transmission would have problems with this product. I have 40,000 miles on this gear oil with no  problems. Should I expect problems? Also, the rear differential calls for a straight 90-weight  oil. Could I use the Mobil 1 75-90 ?
      -- Bill Clemens, Carlisle, PA
     Mobil 1 Synthetic Gear Lubricant is an API GL-5 lubricant. We do not recommend the use of  Mobil 1 Synthetic Gear Lubricant for any gear application that requires a GL-4 lubricant. If  your vehicle requires an API GL-4 lubricant, you should not use an API GL-5 lubricant. The  additives that are in a GL-5 gear lubricant could cause physical damage to a gearbox that  requires a GL-4 lubricant. You should verify what the OEM recommends for each gearbox on your  vehicle. Since you did not provide any vehicle information in your inquiry, we cannot make any  determination of suitability for the lubricants in use.
 
      12/19/2001  Gear Lube In A Triumph
         I have a '72 Triumph TR6. The manual gearbox contains brass and bronze parts. I've  heard that some additives in modern fluids can attack these parts. Is Mobil 1 Synthetic Gear  Lube safe in these older gearboxes?
      -- TSN8725@aol.com, Orland Park, IL
     We would not recommend using Mobil 1 Synthetic Gear Lubricant in the Triumph TR6 manual  transmission. Mobil 1 Synthetic Gear Lubricant meets the requirements of API GL-5 service, while  manual transmissions require an API GL-4 or lower. The additive level of a GL-5 lubricant can be  harmful to a synchromesh transmission over long-term use.
 
Mitsu really shouldn't have spec'd two types of fluids as being compatible with our cars.  It  really should've been spec'd as just GL4.

It is only the transmission itself which has copper parts in it.  The transfer case and rear diff  can take pretty much any lube you want to use as long as it meets the minimum specs.

Spec is 115-156psi with the standard value being 156 psi and the lower limit being 115 psi.  The  allowed variance between cylinders is 14 psi.
 
Since your values are all similarly low, I'd guess that you forgot to unplug the crank position  sensor so the ECU was still injecting fuel, which will cause a lower reading from washing away  the oil layer on the cylinder walls.
 
The crank sensor connector is on the front timing belt cover between the "V" of the motor.   There are two plastic connectors - the crank sensor is the one towards the front of the car.  If  you want to be extra cautious, you can unplug both (the other is the cam angle sensor).
 
The tests should also be run on a warm motor, so if it was cold that may be another reason the  readings were low.  Since they are all pretty similar, if the car runs okay I don't think I'd  worry about it too much.

I did a compression test while trying to track down a problem on my car this weekend as well:

Cyl #2:  151
Cyl #4:  122

Cyl #6:  150
 
Cylinders 4 and 5 are about 30 PSI lower than the others.  When I put a few drops of oil in,  both cylinders' compression went up 10-15 PSI.  That points to worn rings, right?
 
The engine runs very smoothly.  I did the test on a cold engine...maybe I'll try it again on a  warm engine.  I'm inclined not to mess with it; these numbers don't seem worth a rebuild to me.   What do you think?

Make sure you do the compression test with motor warm, and you have the throttle WIDE OPEN.   Since you may have the manifold off anyway to access the rear plugs, usually that's not a  problem unless you are checking only the front 3 and manifold is still on.
 
The fact that all are so close makes me more suspicious your gauge is off, the throttle was  closed, the engine was cold, or such than that all cylinders are SO bad to almost exactly the  same amount...
 
Look at your compression gauge. What does it read BEFORE the tests? Sometimes you have to add or  subtract a correction factor, if the needle reads something other than zero.
 
Do you have aftermarket cams, cam gears?
Are you cranking the motor at least 5-10 revolutions?

Worn rings, typically - but not necessarily.  My car read the same as yours,
with three fractured pistons.  About 155 on the good ones, 120 on the busted
ones.  Car ran okay until the point where it threw chunks of ring land through
the valves and into the other cylinders, and crushed the electrodes of the
spark plugs.
 
What was the other problem that you were trying to diagnose that made you try
a compression test?
