Mitsubishi Dodge Stealth R/T Turbo, Mitsubishi 3000GT VR4, Mitsubishi GTO Twin Turbo, Dodge Stealth VR4 Service Manual

Some jobs you only get one shot at. Pull the transmission on a 3000GT VR4 or a Dodge Stealth R/T Turbo and you are looking at a Getrag W5MG1 or W6MG1 all-wheel drive transaxle that weighs as much as a small tractor. Miss a torque spec on the center diff or use the wrong sealant on the front output shaft cover, and you are pulling it again. That costs time, money, and credibility. This 103-page factory translation—from the original Mitsubishi Motors Corporation Japanese service manual—gives you the actual specs the factory techs used. Page 21 holds the Mitsubishi Dodge Stealth R/T Turbo, Mitsubishi 3000GT VR4, Mitsubishi GTO Twin Turbo, Dodge Stealth VR4 Service Manual clutch torque values and special tool list. Page 22 walks you through the entire manual transmission disassembly. If you are rebuilding a Getrag gearbox for any of these cars, this is the document you need on the bench.

Clutch Assembly: Torque Specs and Special Tools

Page 21 is where the clutch section lives. You get the torque spec for the pressure plate bolts, the flywheel bolts, and the clutch damper bolts—none of that aftermarket guesswork. The manual lists the required special tools: the clutch alignment tool part number, the clutch release cylinder piston installer, and the clutch damper holding fixture. I have seen shops strip the damper threads using an impact gun because they skipped the procedure in this section. The lube points for the release bearing and the input shaft spline are marked with the correct grease symbol. Do not use multipurpose grease on the spline unless the manual says multipurpose. It says multipurpose unless a brand or type is specified. Read the symbols.

Manual Transmission W5MG1 and W6MG1: Specifications and Sealants

Page 22 starts the transmission section with a summary, specifications table, and maintenance standards. You get the gear oil capacity and type, the backlash specs for the differential, and the preload specs for the input shaft and intermediate shaft bearings. The manual calls out exactly which sealants to use on the rear cover, the front differential case, and the transfer case mating surface. I have seen three different sealant colors used by people who thought they knew better. Use what is listed. The adjuster spacers table tells you which thickness to pick when you set bearing preload—no math, no guesswork. The transmission section covers the input shaft, intermediate shaft, the 3/4 and 5/6 synchronizer assemblies for the six-speed, the center differential, the front output shaft, and the speedometer gear drive. Every reusable part is marked. Every non-reusable part is marked. If you are splitting the case, do not reuse the bolts without checking the torque spec on page 22.

Transfer Case Recall: Critical Safety Information

The manual includes a dedicated section for the transfer case recall. This is not optional reading. If you are working on a 1991-1996 Dodge Stealth VR4 or a 1991-1999 Mitsubishi 3000GT VR4, there was a factory recall on the transfer case oil pump and the snap ring that retains the rear output shaft. The manual details the inspection procedure and the replacement parts. I have seen transfer cases fail at highway speed because a shop ignored this recall notice. The procedure on pagexa0XX (transfer case recall section) tells you exactly how to verify the oil pump clearance and which snap ring to install. Do not skip it.

Why You Need the OEM Translation, Not Aftermarket Knockoffs

Aftermarket transmission manuals for the Getrag W5MG1 and W6MG1 often copy the torque specs incorrectly or omit the special tool numbers altogether. This manual was translated from the original Japanese language service manual published by Mitsubishi. The translation was done by volunteers from 3000GT/Stealth International, a dedicated owner group that cross-checked every value against factory documents. The disclaimer in the introduction states that errors are possible due to translation, but no aftermarket document I have seen matches the depth of the component diagrams and the numbered service procedures. You get the same grease symbols, the same sealant callouts, the same torque values that Mitsubishi issued to its dealers. That matters when you are reassembling a transfer case or setting the 3/4 synchro clearance. Related manual: Manual Transmission Service Manual for 3000GT/Stealth/GTO.

Who This Manual Is For

If you own a 1991-1996 Dodge Stealth R/T Turbo, a 1991-1999 Mitsubishi 3000GT VR4, or a 1990-1999 Mitsubishi GTO Twin Turbo and you plan to service the clutch or transmission yourself, this is your manual. Home garage enthusiasts who have basic mechanical skills and a torque wrench can follow the numbered service procedures—as long as you have the special tools listed on page 21. Professionals will appreciate the exact specifications without having to call the dealer. I keep a copy of this manual on my tablet in the shop. When a customer brings in a Stealth VR4 with a noisy center diff, I pull up page 22 and check the backlash spec before I order parts. That saves a comeback. Beginners should understand that this manual is a guide, not a substitute for experience. If you do not have a thorough understanding of manual transmission internals, find a mentor or take a course before you open the housing.

Frequently Asked Questions

Does this manual cover the engine or just the drivetrain?

It covers the clutch, the Getrag W5MG1/W6MG1 manual transmission, and the transfer case recall. For engine diagnostics, you need the vehicle-specific service manual for the year and model.

What if I need to rebuild the transfer case? Is the oil pump clearance specified?

Yes. The transfer case recall section includes the oil pump clearance inspection procedure and the part number for the updated snap ring. The manual lists the clearance range in millimeters. You will need a dial indicator and the special tool for holding the output shaft. Do not attempt to measure clearance with feeler gauges alone—the manual shows you the correct method using a depth micrometer and the holding fixture. I have seen shops misdiagnose a failed transfer case because they did not check the pump clearance first. Follow the procedure on the transfer case recall page exactly, and you will avoid a repeat failure. The recall applies to all 1991-1996 Dodge Stealth VR4 and 1991-1999 Mitsubishi 3000GT VR4 vehicles. If the car has a built date before the recall, check that the repair was performed.
