Ate up fourth gear on a no-lift-shift, which in turn cuz some hell. Guess its on for something that's cyro treated inside out.

I was able to salvage the shift forks, shift rails, spool, and viscous elimenator. Guess I'll send those out with my other trans and ask for something dumb for this toy car.

dang thats some creazy shizat how much pwoer are you putting through the tranny?

id give tre a call, maybe you can get it replaced if it was only 7,000 miles old.

The pics aren't loading right now, what year 3/4 did you have? It's not hard at all to crack the later 3/4s. I've killed a couple of them.

Can you give some close-up pics of the other gears? Did you get that trans direct from TRE? From what I see so far, the treatment on the gears does not look like what TRE does.

Any more specs on the car? What hp, clutch, what ET does it run, etc?

Kevin

sorry for any confusion, corrected the title say TRE "rebuilt" trans.

HP/FT-lbs unknown, ET unknown. Just put together this new setup near the end of summer and got it together running well the day before the tracks up here shut down. Wanted to run it for a couple of weeks then get a dyno tune, when I started to get a little more aggressive and started to eat up stuff. I was very disappointed.

So far I've garnaded two Spicier U-Joints (yes someone mention oem is the strongest and I will use those next) and kinda did something to my rear diff (about 60ish degrees of backlash). I'll be rebuilding that this week. This is only on stutterbox launches and hefty clutch slipping to sorta ease the power on.

I'm looking forward to the upcoming season, just got to put a drivetrain together that will hold well.

Here's some more pics

The carnage!! sucker!!!...you got owned!!!

dont worry, I just replaced a tranny last week, i got owned too! :thumbdown . For a moment there i thought I was looking at my tranny!

Oh damn.



That is all.

, yeah I'm pretty sure I got every gear cept reverse. even the center and front diffs.

What is your invoice number?

I've changed the first post after talking with the guy I went through for this trans. There was some confusion between us and a different shop rebuilt it using parts from TRE. Even though this is a rare failure, I still don't want a reputable company to look bad for something they were not involved with. Hey, the spool and viscous elimenator held up well

Although this thread's title has been changed, I still want to make something clear to everyone.

Please understand that TRE did not rebuild this transmission.

It was rebuilt by someone else who only bought parts from us.

First, the gearsets are not from TRE.

There are several obvious differences between the gearsets that we use in our transmissions and the parts that you can buy from us. The gearsets that we use while rebuilding a transmission are hand selected against our own tolerances. We carefully match wear patterns, fully detail, and modify the gearsets. Some of the parts are shot peened for stress relief while others are REM polished to insure smooth shifting. The transmission case is modified to improve lubrication to the various parts which extends the life of the transmission. I see no such evidence of the above in any of these photos that have been posted.

The photos you have posted here show this transmission to be an early model 8903.1 – 9006.1 because it uses the early reverse shift mechanism and it also doesn’t have a reverse synchro or cone brake.

Anyone who has ever bought a transmission from us knows that we do not sell the early model transmissions. The parts that were used in the early model transmissions were not designed for the high torque output that the 4g63 can produce. These early transmissions have more in common with the Colt Vista vans that were built from 87-90 than the DSM transmissions of late.

How many miles total that are on this transmission before the rebuild is unknown but the failure is a text book example of what can happen when old bearings are re-used or if the builder did not set-up the pre-load on the bearings or check for gear misalignment issues. The tapered roller bearing on the end of the intermediate shaft, next to that 4th gear, is not a new bearing but an old pitted bearing most likely the original bearing.

I’d also have to assume that the builder did not reshim the bearings and just used the old bearings shims. This is not wise practice or something that we do. I have over 150 different part numbers for the bearing shims and that doesn’t include the snap rings of varying thickness. When a transmission is built in my shop you can bet your dollar I have the shims and have established proper turning torques of the gearsets.

Secondly, we do not use red silicone sealant and our transmissions carry a 4 month warranty.

Next time please choose your wording a little more carefully. I don’t like having to make posts like this.

I prefer email because Ming and I are busy building transmissions for our customers.

Thanks for the space

50K+ on my TRE build so far and it still shifts great!! My next trans will be coming there.


While you're on...... When a VC goes bad, what's the easiest way to check if it's bad? Also, when it does go bad, will it at any point cause any excess powertrain drone/vibration/whine?

I've got a bad powertrain born NVH issue and I think it's one of three things:
1. grounded engine/trans mount. (I've changed out 2 of 4 and no change)
2. Bad T-case (not sure how to tell)
3. Bad V-coupler? (if it produces noise)

Weird thing is it's louder when making a sweeping left turn (on highway) vs a right turn, which leads me to think it's an engine mount. However, in a left hand turn the outer wheel is turning faster and would be working the VC more, correct? If it's bad, would it 'growl'?

Not to get off topic, but it's Trans related and who better to ask than Jon.

I'll beat Jon to this one.

What you described is the classic behavior of a failing right side wheel bearing. Lift the wheels up and try to wiggle them. One on the right side is going to have some slack.

What years are you referring to by early? My 97 gsx tranny looks just like the one in the pics and has no reverse syncro.

REM polished gear


Not REM polished.



Not DSM gears but the same treatment.

Jon should show final pictures of his trans components next to stock stuff... A before and after would sell some tranies.

I'll post some info later on over the weekend. I'll share some of the tricks but not all of them, after all I'm in the business of rebuilding transmissions and besides all of you "experts" already know it all in the first place

I think you don't have to go into detail on everything. Your average customer does'nt know rem polishing from Mike Stipe REM...

The point is on your site to make some of the black magic or voodo that you do something visual and tangible.. Like the guy who would never open his own trans case could think.. This is what my gears looked like in this thing before... this is after.. Then they think hmm These guys are worth the $.. Honestly, for the average joe it's hard telling from some of the small pictures on the site.

It's like not knowing what is actually done and bragging about what you bought is like the honda people with a axle back exhaust and VTEC but don't know what VTEC even is.

"What years are you referring to by early? My 97 gsx tranny looks just like the one in the pics and has no reverse syncro."

The tooth profile and helix angles are different. The transmission has a single synchro 2nd gear. The engagement teeth on 1st & 2nd are different. The synchro cone angles are different. The 3rd/4th hub & sleeve are smaller. The shift rails ends are smaller and the 3rd/4th shift fork is different. The input shaft is weak under 3rd gear. The center diff is better. There are......at least a dozen or more things that I didn't mention that are different as well but I won't go into the details.

Good point MNGXS.

I'll bring some eye candy to this thread over the weekend.

Right now I have to shag ass over to the other side to help with an AWD ice racer.
