Here is some info for those of you brave enough to pull your own box apart :thumbsup:
All info comes from Tim Zimmerman ( twicks69 ) on the dsmtuners forums etc.
He has been playing with these boxes for a long time and knows his stuff people!
http://www.tmzperformance.com/

Here are the specs he has posted. Please don't argue about them, all I am doing is reposting specs which have been proven to work for the various scenarios listed!


The following is for W5M33 AWD 5-speed transmissions:

Ok, stock specs are:

The Preload Setting is listed in SAE (inches):

Input Shaft --> 0.000" - 0.002" ENDPLAY
Intermediate Shaft --> 0.003" - 0.005" PRELOAD
Center Differential --> 0.003" - 0.005" PRELOAD
Output Shaft --> 0.003" - 0.005" PRELOAD
Front Differential --> 0.002" - .0067" ENDPLAY

These are what I normally use:

Stock/Street Transmissions with less than 400TQ at the crank:

Input Shaft --> 0.004" - 0.007" PRELOAD
Intermediate Shaft --> 0.005" - 0.007" PRELOAD
Center Differential --> 0.005" - 0.007" PRELOAD
Output Shaft --> 0.003" - 0.005" PRELOAD
Front Differential --> 0.002" - .0067" ENDPLAY

Street/Strip Transmissions with less than 600TQ at the crank:

Input Shaft --> 0.005" - 0.007" PRELOAD
Intermediate Shaft --> 0.007" - 0.009" PRELOAD
Center Differential --> 0.005" - 0.007" PRELOAD
Output Shaft --> 0.003" - 0.005" PRELOAD
Front Differential --> 0.002" - .0067" ENDPLAY

All out RACE Transmissions that are Rebuilt/Inspected regularly with more than 600TQ at the crank:

Input Shaft --> 0.007" PRELOAD
Intermediate Shaft --> 0.008" - 0.010" PRELOAD
Center Differential --> 0.005" - 0.007" PRELOAD
Output Shaft --> 0.004" - 0.006" PRELOAD
Front Differential --> 0.002" - .0067" ENDPLAY

For Extremely HIGH HP/TQ transmissions (As in ~900-1000+TQ at the crank):

Input Shaft --> 0.007" PRELOAD
Intermediate Shaft --> 0.010" - 0.012" PRELOAD
Center Differential --> 0.005" - 0.007" PRELOAD
Output Shaft --> 0.004" - 0.006" PRELOAD
Front Differential --> 0.002" - .0067" ENDPLAY



These figures are normally what I use, unless a customer has a specific number they want to run for shims.

As well, each transmission rebuilder will shim differently, or not even reshim whatsoever (reusing stock shims). Most transmission rebuilders will not tell you these numbers whatsoever, as this is what makes their transmissions shift like butter with all the other mods that they do to the shift rails, hub and sliders, gears, linkage, etc.

I would recommend using a quality Micrometer that is accurate to 0.0001", and I normally do two or three seperate solder-tests per bearing race and then take the average of each test to see if there is anything out of the ordinary, and then I select the shim by adding the preload figure listed above to the solder average thickness, or subtract the endplay figure listed above from the solder average thickness.

If you need the part number for a shim, reference a factory service manual for all the part numbers of shims for each transmission model.

How much time do you spend in a parking lot with your performance car? If you do a lot of parking lot driving, and hang out in parking lots, chances are you are a ricer, go home and read import tuner. If you’re complaining about noise you should not be modifying your car. You should also consider no longer being a man, please hand in your genitals at the door.

lol Rob! It was sending me mad trying to find the correct info so I could finish rebuilding my box so I figured I had better store it somewhere :)

The Mitsubishi numbers are for the inner and outer bearings, I don't recall which are which but I could always look it up!

Good sources for bearings and shims? Mainly shims!
My bearing shop has had the task of getting me some stuff for like 2 weeks, and i'm over it.

Local Mitsu Parts cant get me the shims I want. I even took part numbers in for them.


Anyone know a good website?
