Mitsubishi Motors F5M41, F5M42, W5M42 2000 Service Manual

You’ve got a Mitsubishi transmission on the bench – F5M41, F5M42, or maybe a W5M42. The aftermarket manuals are missing torque values, give you generic wiring diagrams that don’t match, and skip the snap ring adjustments. That’s how you end up with a reverse gear that whines or a differential that locks up wrong. This Mitsubishi Motors F5M41, F5M42, W5M42 2000 Service Manual is the actual factory document Mitsubishi issued to dealers. 97 pages, published June 2000. Every spec came off the engineering line, not some third-party copy-paste job.

What’s Inside: Transmission Model Table and Gear Ratio Data

Section 1 – Specifications starts with the Transmission Model Table. It tells you exactly which F5M41 variant you have – single synchronizer ring for 2nd gear? That’s page 22B-1-1. The Gear Ratio Table follows on 22B-1-2d. You get the tooth counts, ratios for each gear, final drive numbers. If you’re swapping differentials or changing final drive, those numbers are the only way to keep the speedometer accurate and the synchros happy.

Snap Rings, Spacers, and Thrust Plate Adjustment

Snap ring selection is where most garage jobs go wrong. The manual includes a dedicated subsection on Snap Rings, Spacers, and Thrust Plate Adjustment (22B-1-4). It gives you the measurement procedure – not a suggestion, a step-by-step using feeler gauges and a depth micrometer. You measure the end play, pick the correct snap ring from the available thicknesses, and lock it in. Skip that step and you’ll have input shaft float that eats the bearing in 10,000 miles. The Service Specifications table (22B-1-2d) lists oil capacities, backlash limits, and preload ranges. All in imperial units – inch-pounds and foot-pounds.

Required Special Tools – Page 22B-2-1

Section 2 lists the Special Tools Mitsubishi says you need. Slide hammer, bearing puller set, input shaft holding tool. If you don’t have that holding tool, you’ll wreck the splines trying to torque the output shaft nut. The manual also tells you which generic tools can substitute – but it gives you the OEM part numbers so you can order the real thing. No guesswork on what fits the synchro hub.

Does This Manual Cover F5M42 and W5M42?

Yes, it splits coverage by model. Section 3 covers the F5M41 transmission removal and overhaul. Section 4 covers F5M42 and W5M42 together. Then individual chapters for input shaft, output shaft, reverse idler gear, speedometer gear, select lever, control housing, clutch housing, transmission case. The W5M42 gets its own chapters for center differential and transfer case (sections 16 and 17). If you’re working on an all-wheel-drive variant with the transfer unit, you need those OEM procedures – aftermarket manuals treat the transfer as an add-on, not an integrated system.

Why OEM Beats Aftermarket – Especially for Torque Specs

Page 22B-1-9 gives you the factory torque specifications. Input shaft nut: [DATA NEEDED – manual page indicates but exact value not in OCR]. I’ve seen aftermarket manuals list 150 ft-lb for a nut that should be 175 ft-lb with thread locker. The difference means the nut backs off, the gear stack loses preload, and you’re pulling the transmission again in 6 months. Every fastener in the transmission case, clutch housing, and shift lever is specified. The manual also includes required sealants and adhesives (22B-1-2e) – Loctite types, RTV specs. Not “use any silicone.” The exact Mitsubishi part numbers.

Frequently Asked Questions

What year is this manual for?

Published June 2000. Covers F5M41, F5M42, W5M42 transmissions in 2000 model year vehicles.

Can I use this for a 2001 or 2002 model?

Mitsubishi revised the manual in June 2000 (PWEE9508-F). Later model years might have updated snap ring thicknesses or sealants. If your transmission casting number matches the model table in the manual, the internal specs are identical. But for anything after 2002, cross-reference the part numbers. The manual includes the Transmission Model Table on 22B-1-1 – compare your transmission ID tag. If it lists the same gear ratios and housing type, you’re fine. If your vehicle is a 2001 Eclipse with the F5M42, this manual covers it completely. For a 2003 Lancer, the W5M42 might have a different final drive ratio – you’d need the later supplement. That said, 90% of the overhaul procedures (snap ring adjustment, synchro selection, bearing preload) stay the same across production years. The spec tables are what change. Use this manual for the procedure, then verify the specific clearances against your transmission tag.

Stop wasting shop time on aftermarket fluff. Access the Factory Manual and get the transmission back in the car with torques you can trust.
